1 Preparing hosts for the update

  1. ECSS-10 version 3.17 supports two licensing types: file-based licensing (with or without a token) and ELM licensing. Depending on the licensing type, different commands will be executed during the update.

    You can check which type is used on your SSW with the following command:

    /cluster/storage/ds1/licence/list-licence 

    The output for file-based license is as follows:

    /cluster/storage/ds1/licence/list-licence
    ┌──┬───────────────────┬────────────┬──────┬───────────────────┬────────────────────┬────────────┐
    │Id│Creation date(UTC) │   SSW ID   │Active│    Description    │Expiration date(UTC)│ Time left  │

    └──┴───────────────────┴────────────┴──────┴───────────────────┴────────────────────┴────────────┘

    The output for ELM license is as follows:

    /cluster/storage/ds1/licence/list-licence                  
    ┌──┬───────────────────┬────────────┬──────┬────────────────┬────────────────────┬────────────┐

  2. Preparing gluster volume for an update.
    If one of the cluster nodes becomes unavailable, issues with the files may arise. Once the node is back online, the files will be out of sync, requiring you to manually initiate synchronization between the nodes.
    To resolve this issue, use the cluster.favorite-child-policy parameter.
    When enabled, all files that are split will be automatically synchronized with each other according to the specified rule.
    To enable this parameter, use the following command:
    sudo gluster volume set ecss_volume cluster.favorite-child-policy size
    sudo gluster volume set ecss_volume cluster.favorite-child-policy size
    volume set: success
     sudo gluster volume info
     
    Volume Name: ecss_volume
    Type: Replicate
    Volume ID: 4bc875b1-f966-44e2-9b3f-04f3a7af83f3
    Status: Started
    Snapshot Count: 0
    Number of Bricks: 1 x 2 = 2
    Transport-type: tcp
    Bricks:
    Brick1: 10.0.10.51:/var/lib/ecss/glusterfs
    Brick2: 10.0.10.52:/var/lib/ecss/glusterfs
    Options Reconfigured:
    cluster.favorite-child-policy: size
    performance.client-io-threads: off
    nfs.disable: on
    transport.address-family: inet
    storage.fips-mode-rchecksum: on
    cluster.granular-entry-heal: on
    
    
  3. When updating the cluster, update the servers one at a time. This ensures that one of the servers will always be running during the update, and service operation will not be interrupted. To split the cluster, use the ecss-control tool on both servers.
    SIP signaling is exchanged via the SIP-VRRP IP address. This functionality is implemented to enable IP address migration to another host in the event of a failure, shutdown, or maintenance of the primary host. IP address migration is managed by the keepalived service on each host.
    To redirect traffic to the first server (ecss1), you must stop keepalived on the second host (ecss2). In this case, both SIP-VRRP IP addresses will be on the first host (ecss1). Run the following command:
    sudo systemctl disable --now keepalived.service
  4. Use the ifconfig command to check that all VRRP IP addresses are located on ecss1 (VRRP-SIP1/VRRP-SIP2):
    ifconfig
  5. All nodes on the server that is being updated first should be masked and have their autorun disabled:
    sudo systemctl mask --now ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip ecss-sorm

    After the specified command is executed, the notification will appear.

    Warning: The unit file, source configuration file or drop-ins of ecss-ds.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-mycelium.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-mediator.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-core.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-pa-sip.service changed on disk. Run 'systemctl daemon-reload' to reload units.

    These messages are not an error. Continue the procedure.

  6. On ecss1, split SSW into two independent servers using the following command:

    The ecss-control command uses standard hostnames: ecss1/ecss2.


    sudo ecss-control detach
    Check the status:
    sudo ecss-control status

    sudo ecss-control detach
    detach host: ecss2, ip: 10.0.10.52
    complete
    sudo ecss-control status
    locked ip: 10.0.10.52


2 Preparing for updating SSW services

  1. Update the SSW repository:
    sudo sh -c "echo deb [arch=amd64]  http://archive.eltex.org/ssw/jammy/3.18 stable main extras external > /etc/apt/sources.list.d/eltex-ecss10-stable.list"
  2. Update the packets:
    sudo apt update

3 Updating SSW services on ecss2

  1. Make a full backup.
  2. Update PostgreSQL:
    1. Check the addresses where the Postgres database is running, run the following command:
      psql -Upostgres -decss_storekeeper_db -h localhost -p5439 -c "SELECT node_local_dsn FROM bdr.bdr_nodes;"

      Default password is "postgres1"


      psql -Upostgres -decss_storekeeper_db -h localhost -p5439 -c "SELECT node_local_dsn FROM bdr.bdr_nodes;"
      Password for user postgres: 
                                          node_local_dsn                                     
      ---------------------------------------------------------------------------------------
       host=10.0.10.51 port=5439 dbname=ecss_storekeeper_db user=postgres password=postgres1
       host=10.0.10.52 port=5439 dbname=ecss_storekeeper_db user=postgres password=postgres1
      (2 rows)
      
    2. Disable the Docker container:
      sudo docker compose -f /srv/ecss/ecss-postgres-bdr-ssw/docker-compose.container.yml down

       sudo docker compose -f /srv/ecss/ecss-postgres-bdr-ssw/docker-compose.container.yml down
      [+] down 2/2
       ✔ Container ecss-postgres-bdr-ssw-postgres-container-1 Removed                                                                                                                           
       ✔ Network ecss-postgres-bdr-ssw_default                Removed 
    3. Remove the old deb packet, since it doesn't support the upgrade option:
      sudo apt remove ecss-postgres-bdr-ssw

      Execut the remove command, not purge, because 'remove' saves the 'volumes' directory containing the database tables.


      sudo apt remove ecss-postgres-bdr-ssw
      Reading package lists… Ready
      . . .
      The following packages will be DELETED:

      Would you like to continue? [Y/N] y
      Removing ecss-postgres-bdr-ssw (17.1.0.59+ssw) …
    4. Install the new deb package:
      sudo apt install ecss-postgres-bdr-ssw 

      During installation, you will be asked the same questions as during the initial installation:
      Your answers must match the instructions in the procedure exactly; otherwise, the system will attempt to create a new database, and the installation will fail.

      QuestionAnswerExample

      Current IP address of the network interface.

      Select an IP address: the same one used during the initial installation,
      since replication is tied to specific IP addresses.

      (checked in step "a", 10.0.10.52 in the example).

      10.0.10.52 (must be specified)

      Installation in a cluster? 
      Select <Yes> if the package is being installed on a cluster node.
      Yes (default value)

      Is this node master?

      Answer NO! Otherwise it'll try to create new bdr, 
      which will be impossible and will lead to installation error).



      No (default value)

      IP address used to connect to the cluster:

      IP of the neighbor node (specified during its installation, checked in step "a", 10.0.10.51 in the example).




      10.0.10.51 (must be specified)


      sudo apt install ecss-postgres-bdr-ssw

    5. After the installation make sure, that the new image is loaded and the docker started. Run the following command:
      docker ps

      docker ps
      CONTAINER ID   IMAGE                                           COMMAND                  CREATED         STATUS         PORTS                                         NAMES

  3. Updating SSW.
    1. Updating the ecss-dns-env package:
      sudo apt install ecss-dns-env
    2. Updating the ecss-user package:
      sudo apt install ecss-user
    3. Updating the ecss-utils package:
      sudo apt install ecss-utils
    4. Install the License Provider package:

      sudo apt install ecss-license-provider

      When installing the ecss-license-provider package the following questions will be asked:

      QuestionsAnswersExamples

      License Provider listen ip:

      0.0.0.0 (default value)

      License Provider listen port:4321 (default value)

      Log level:info (default value),
      other options: debug, error, info

      License Provider cluster key:

      specify a unique name
      ecss-lm-cluster (default value)

      Managers with the same names will attempt to form a cluster for mutual failover.


      The data is saved to the /etc/ecss/ecss-license-provider/config.env file:

      ECSS_LM_HOST=0.0.0.0
      ECSS_LM_PORT=4321
      ECSS_LM_LOG_LEVEL=info
      RELEASE_COOKIE=ecss-abf-lm-cluster

      License Provider (LP) configuration

      The ecss-license-provider service uses two configuration files: /etc/ecss/ecss-license-provider/config.env and /etc/ecss/ecss-license-provider/config.yaml.

      The information is saved to the config.env file when the ecss-license-provider is installed.

      The config.yaml file contains general settings for connecting to the ELM server and information about licenses: what licenses to take, where to take them from, and where to send them, all this information should be configured manually.

      elm_addresses: []
      licenses: []
      ecss_nodes: []
      To fill out these fields, open the ecss-elm-adapter configuration file used in the version 3.17 /etc/ecss/ecss-elm-adapter/config.env:
      cat /etc/ecss/ecss-elm-adapter/config.env 
      ELM_HOST=elm.eltex-co.ru
      ELM_PORT=8099
      ECSS_PRODUCT_ID=ECSS2000000
      ECSS_LICENSE_KEY=ssw987654
      LOG_LEVEL=info
      LICENCE_FAIL_TIMER_SECONDS=10
      LICENCE_PULL_TIMER_SECONDS=360

      In the elm_addresses field, you must specify a list of ELM servers to which you want to connect to obtain licenses.
      First address in the list is used as the main one. Additional lines contain backup addresses.
      Example:

      elm_addresses:
       - "elm.eltex-co.ru:8099"
       - "192.168.111.22:8099"
       - "elm-3.eltex.loc:8099"



      Then licenses in the licenses field are specified.

      • The id can be anything, as long as it is unique for each license. It only affects the license address on the License Provider itself (e.g., 0, 1, 2, 3).
      • kind. For SSW, only SSW (in uppercase) is supported.
      • type is set to elm if this license is to be requested from the ELM server. If you need to use an SSW file-based license, set the type to ecss_license.
        • For the elm type, you must specify the license_key and product_id fields to identify the license.
        • For the ecss_license type, specify the license field, which contains the static license key.

      license_key = ECSS_LICENSE_KEY and product_id = ECSS_PRODUCT_ID parameters must match the data previously uploaded to the ELM server.

      ecss_nodes block.

      You must specify the details of the services that will receive the license. A service is defined by three parameters:

      • id - the service identifier. In the case of SSW, this must match the ECSS_ID of the SSW being licensed.
      • kind - the type of service being licensed. As with the licenses block, the SSW and AUP types are supported. For SSW, only the SSW type is supported.
      • license_id - the identifier of the license that will be sent to this service. It corresponds to the license identifiers from the licenses block
      Two SSWs with different ECSS_IDs cannot receive the same license; a configuration with such an assignment will be marked as invalid.
      Additionally, two SSWs with identical ECSS_IDs cannot simultaneously obtain the same license from a single License Provider; therefore, it is extremely important to set your ECSS_ID correctly and ensure it is unique, at least within the scope of the License Provider being used.

      ECSS_ID format.
      It must begin and end with a Latin letter or a digit; periods and dashes may be used within the string. 

      [A-Za-z0-9][A-Za-z0-9.-][A-Za-z0-9]

      For an SSW operating in a cluster, specify only one entry in the ecss_nodes block per cluster; you cannot specify entries individually for each host. Otherwise, two requests with the same ECSS_ID will be generated, which is not allowed.

      elm_addresses:
       - "elm.eltex-co.ru:8099"
      licenses:
       - id: 0
         kind: SSW
         type: elm
         license_key: "ssw987654"
         product_id: "ECSS2000000"
      ecss_nodes:
       - id: eltex1.test
         kind: SSW
         license_id: 0

      Restart the ecss-license-provider.service service to up date the configuration from the /etc/ecss/ecss-license-provider/config.yaml file via the following command:

      sudo systemctl restart ecss-license-provider.service

      No addditional actions required.

    5. Update the ecss-node package:
      sudo apt install ecss-node

      ecss-node installation questions:

      QuestionAnswerExample

      Cookie for the core node: (specify the unique cookie for the core, the example uses ecss-core-example)

      In a cluster cookies should be unique for the nodes of the same type.

      ecss-core-example (needs to be entered)

      Cookie for the ds node: (specify the unique cookie for the ds, the example uses ecss-ds-example)

      In a cluster cookies should be unique for the nodes of the same type.

      ecss-ds-example (needs to be entered)

      Cookie for the mediator node: (specify the unique cookie for the mediator, the example uses ecss-mediator-example)

      In a cluster cookies should be unique for the nodes of the same type.

      ecss-mediator-example (needs to be entered)

      Cookie for the pa-sip node: (specify the unique cookie for the pa-sip, the example uses ecss-pa-sip-example)

      In a cluster cookies should be unique for the nodes of the same type.

      ecss-pa-sip-example (needs to be entered)

      Cookie for the mycelium node: (specify the unique cookie for the mycelium, the example uses ecss-mycelium-example)

      In a cluster cookies should be unique for the nodes of the same type.

      ecss-mycelium-example (needs to be entered)

      Accept all configuration file changes


  4. Enable the nodes.
    Enable the SSW services using the following commands: 
    sudo systemctl unmask ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip ecss-sorm

    sudo systemctl enable ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip ecss-sorm

    Before starting the SSW nodes, change the cluster name (to any other name—just make sure it doesn’t match that of a neighbor (ecss1) or any other potential PBX in your network, otherwise it will try to connect to it). To do this, in the /etc/ecss/ecss-mycelium/mycelium.config file change the "{cluster_name, 'eltex.test'}" line to "{cluster_name, 'eltex1.test'}", for example.

    sudo nano /etc/ecss/ecss-mycelium/mycelium.config
    [
        {mycelium_broker, [
            {cluster_name, 'eltex1.test'},
            {compress_module, elx_data_nif},
            {session_gc_timeout, 3000},
            {queue_gc_timeout, infinity}
    . . .


  5. Starting SSW on ecss2. Start the following services:
    ecss-mycelium
    sudo systemctl start ecss-mycelium
    ecss-ds
    sudo systemctl start ecss-ds
    ecss-core
    sudo systemctl start ecss-core
    ecss-mediator
    sudo systemctl start ecss-mediator

    Do not start PA-SIP yet

  6. Check the status of services by running the system-status command in CoCon:
    /system-status

  7. Disable the ecss-elm-adapter service on ecss1 using the command below:
    sudo systemctl stop ecss-elm-adapter.service

    Configure SSW connection to License Provider by running the command below in CoCon, (in the example License Provider is installed in a cluster, host IPs are 10.0.10.51 and 10.0.10.52. Port value is taken from the /etc/ecss/ecss-license-provider/config.env  file, 4321 by default):

    /system/licence/manager/set --hosts [https://10.0.10.51:4321, https://10.0.10.52:4321]

    If License Provider is installed on SSW hosts specify the OAM IP addresses.

    After command execution check the connection status using the following command:

    /system/licence/manager/show-status           
    ┌───────────────────────┬───────┬─────┐
    │         Host          │Current│Alive│
    ├───────────────────────┼───────┼─────┤
    │https://10.0.10.51:4321│*      │true │
    │https://10.0.10.52:4321│       │true │
    └───────────────────────┴───────┴─────┘

    All hosts should have the alive=true status. One should have the "current" status. 

    • Current – shows to which host the SSW is connected. If there is a connection, it is specified by *, and if there isn't – nothing is specified.
    • Alive – shows the host availability status (healthcheck).

    A lack of connection to the License Provider or ELM will result in a loss of access to the token, leading to critical failures and a transition to emergency mode; after this period, if the connection is not restored, the system will switch to the default license.

    This behavior applies only when operating in ELM mode.

    If status of one of the License Provider hosts is current, a request for uploading the license to SSW can be sent using the following command:

    /cluster/storage/ds1/licence/request

    sudo apt install ecss-call-api

    Updating the ecss-peeper-client package.

    sudo apt install ecss-peeper-client
  13. Delete the no longer used ecss-elm-adapter package using the following command:
    sudo apt purge ecss-elm-adapter

    No additional actions are required

4 Transferring the load to ecss2 

  1. Start the keepalived service.
    Before starting the keepalived service, the ecss-pa-sip service should be started:
    sudo systemctl start ecss-pa-sip

    sudo systemctl enable --now keepalived

    Starting the ecss-pa-sip and keepalived services transfers traffic from ecss1 to ecss2. This is the first step of switching traffic to ecss2, complete transfer will happen after disabling the keepalived servcie on ecss1 during the following steps.

  2. Prepare ecss1 for the update by transfering all traffic to ecss2 (the command is performed on ecss1):
    sudo systemctl disable --now keepalived.service
  3. Use the ifconfig command to make sure that all VRRP addresses (VRRP IP-SIP1 / VRRP IP-SIP2) are located on ecss2.
    ifconfig

5 Preparations on ecss1

  1. Do a complete backup
  2. After splitting the cluster is is necessary to disable all nodes on the ecss1 server:
    sudo systemctl mask --now ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip ecss-sorm

    After executing the command the following notification will appear.

    Warning: The unit file, source configuration file or drop-ins of ecss-ds.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-mycelium.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-mediator.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-core.service changed on disk. Run 'systemctl daemon-reload' to reload units.
    Warning: The unit file, source configuration file or drop-ins of ecss-pa-sip.service changed on disk. Run 'systemctl daemon-reload' to reload units.

    These messages are not an error. Continue the procedure.

6 Updating the SSW services on ecss1

  1. Perform clusterization on ecss1:

    The ecss-control attach command is run at this step to make replicating Postgres database possible. This behavior is safe because the node has already been shut down.

    sudo ecss-control attach
  2. Updating PostgreSQL:
    1. Check on which addresses the Postgres database is connected and run the following command:
      psql -Upostgres -decss_storekeeper_db -h localhost -p5439 -c "SELECT node_local_dsn FROM bdr.bdr_nodes;"

      psql -Upostgres -decss_storekeeper_db -h localhost -p5439 -c "SELECT node_local_dsn FROM bdr.bdr_nodes;"
      Password for user postgres: 
                                          node_local_dsn                                     
      ---------------------------------------------------------------------------------------
       host=10.0.10.51 port=5439 dbname=ecss_storekeeper_db user=postgres password=postgres1
       host=10.0.10.52 port=5439 dbname=ecss_storekeeper_db user=postgres password=postgres1
      (2 rows)
      
    2. Disable the Docker container:
      sudo docker compose -f /srv/ecss/ecss-postgres-bdr-ssw/docker-compose.container.yml down

       sudo docker compose -f /srv/ecss/ecss-postgres-bdr-ssw/docker-compose.container.yml down
      [+] down 2/2
       ✔ Container ecss-postgres-bdr-ssw-postgres-container-1 Removed                                                                                                                           
       ✔ Network ecss-postgres-bdr-ssw_default                Removed 
    3. Delete the old deb package since it doesn't support the upgrade option:
      sudo apt remove ecss-postgres-bdr-ssw

      Run remove, not purge, because remove saves the volumes directory containing the database tables.


      sudo apt remove ecss-postgres-bdr-ssw
      Reading packet lists… Ready
      . . .
      The following packets will be REMOVED:

      . . .
      Do you want to continue? [y/n] y
      Removing ecss-postgres-bdr-ssw (17.1.0.59+ssw) …
    4. Install the new deb package:
      sudo apt install ecss-postgres-bdr-ssw 

      During the installation the same questions will be asked as during the initial installation:
      The answers should be exactly as specified in the procedure, otherwise there will be an attempt to create a new database and the installation will result in error.

      Question

      AnswerExample

      Current IP address of the network interface.

      Select an IP: the same one used during the initial installation,
      since replication is tied to specific IPs.

      (checked in step "a" of the instruction, 10.0.10.51 is used in the example)

      10.0.10.51 (needs to be selected)

      Installing to cluster? 
      Select <Yes>, if the package is installed to the cluster node.
      Yes (default value)

      Is this node master?

      NO! (Important! If a different answer is given, the impossible attempt
      at creating a new bdr will be made
      and the installation will result in error)



      No (default value)

      IP address used to connect to the cluster:

      IP of the neighboring node (specified during its installation)

      (checked in step "a" of the instruction, 10.0.10.52 is used in the example)

      10.0.10.52 (needs to be specified)


      sudo apt install ecss-postgres-bdr-ssw
      . . .

    5. After the installation, to make sure that the new image is uploaded and Docker has started, run the following command:
      docker ps

      docker ps
      CONTAINER ID   IMAGE                                           COMMAND                  CREATED         STATUS         PORTS                                         NAMES

  3. Updating the ecss-dns-env package.
    sudo apt install ecss-dns-env

    When updating, accept all new configuration files using Y.
  4. Updating the ecss-user package:
    sudo apt install ecss-user
  5. Updating the ecss-utils package:
    sudo apt install ecss-utils
  6. Install the License Provider package:

    sudo apt install ecss-license-provider

    When istalling the ecss-license-provider package, the following questions will be asked:

    QuestionAnswerExample

    License Provider listen ip:

    0.0.0.0 (default value)

    License Provider listen port:4321 (default value)

    Log level:info (default value),
    possible options: debug, error, info

    License Provider cluster key:

    specify a unique name
    ecss-lm-cluster (default value)

    Managers with identical names will try to form a cluster for mutual redundancy.


    What services should be restarted?

    ecss-license-provider.service (default value)

    The data is saved to the /etc/ecss/ecss-license-provider/config.env file:

    ECSS_LM_HOST=0.0.0.0
    ECSS_LM_PORT=4321
    ECSS_LM_LOG_LEVEL=info
    RELEASE_COOKIE=ecss-abf-lm-cluster

    Configuring License Provider (LP)

    The ecss-license-provider service uses two configuration files: /etc/ecss/ecss-license-provider/config.env and /etc/ecss/ecss-license-provider/config.yaml.

    Information is saved to the config.env file during the ecss-license-provider package installation.

    The config.yaml file contains main settings for connecting to the ELM server: where to take licenses from, whic licenses to take, and where to send them. All of this should be configured manually.

    elm_addresses: []
    licenses: []
    ecss_nodes: []
    To fill in these fields open the ecss-elm-adapter configuration file used in the version 3.17 /etc/ecss/ecss-elm-adapter/config.env:
    cat /etc/ecss/ecss-elm-adapter/config.env 
    ELM_HOST=elm.eltex-co.ru
    ELM_PORT=8099
    ECSS_PRODUCT_ID=ECSS2000000
    ECSS_LICENSE_KEY=ssw987654
    LOG_LEVEL=info
    LICENCE_FAIL_TIMER_SECONDS=10
    LICENCE_PULL_TIMER_SECONDS=360

    It is necessary to specify the ELM servers list to which you wnat to connect to obtain licenses, in the elm_addresses field. First address in the list is used as the main one. Additional lines contain backup addresses.

    Eltex ELM server address is "elm.eltex-co.ru:8099".

    Example:
    - "elm.eltex-co.ru:8099"
    - "192.168.111.22:8099"
    - "elm-3.eltex.loc:8099"

    Then licenses are specified in the licenses field.

    • The id can be anything, as long as it is unique for each license. It only affects the license address on the License Provider itself (e.g., 0, 1, 2, 3).
    • kind. For SSW, only SSW (in uppercase) is supported.
    • type is set to elm if this license is to be requested from the ELM server. If you need to use an SSW file-based license, set the type to ecss_license.
      • for the elm type, you must specify the license_key and product_id fields to identify the license.
      • for the ecss_license type, specify the license field containing the static license key.

    The license_key = ECSS_LICENSE_KEY and product_id = ECSS_PRODUCT_ID parameters must match the data previously uploaded to the ELM server.

    The ecss_nodes block.

    This block must specify the details of the services that will receive the license. A service is specified by three parameters:

    • id - the service identifier. For SSW, this must match the ECSS_ID of the SSW being licensed.
    • kind - the type of service being licensed. Similar to the licenses block, the SSW and AUP types are supported. For SSW, only SSW is supported.
    • license_id - the identifier of the license that will be sent to this service. It corresponds to the license identifiers from the licenses block.
    Two SSWs with different ECSS_IDs cannot receive the same license; a configuration with such an assignment will be marked as invalid
    In addition, two SSWs with the same ECSS_ID cannot simultaneously obtain the same license from a single License Provider; therefore, it is extremely important to set your ECSS_ID correctly and ensure that it is unique, at least within the scope of the License Provider you are using.

    ECSS_ID format.
    It must begin and end with a Latin letter or number; periods and dashes may be used within the text.

    [A-Za-z0-9][A-Za-z0-9.-][A-Za-z0-9]

    For an SSW running in a cluster, specify only one entry in the ecss_nodes block per cluster; you cannot specify entries individually for each host. Otherwise, two requests with the same ECSS_ID will be generated, which is not allowed.

    elm_addresses:
     - "elm.eltex-co.ru:8099"
    licenses:
     - id: 0
       kind: SSW
       type: elm
       license_key: "ssw987654"
       product_id: "ECSS2000000"
    ecss_nodes:
     - id: eltex1.test
       kind: SSW
       license_id: 0

    Restart the ecss-license-provider.service service for updating configuration from the /etc/ecss/ecss-license-provider/config.yaml file using the following command:

    sudo systemctl restart ecss-license-provider.service

    No additional actions are required

  7. Updating the ecss-node package:
    sudo apt install ecss-node

    ecss-node installation questions

    QuestionAnswerExample

    Cookie for the core node: (specify the unique cookie for the core, the example uses ecss-core-example)

    In a cluster configuration, nodes of the similar type should have the same cookies.

    ecss-core-example (needs to be entered)

    Cookie for the ds node: (specify the unique cookie for the ds, the example uses ecss-ds-example)

    In a cluster configuration, nodes of the similar type should have the same cookies.

    ecss-ds-example (needs to be entered)

    Cookie for the mediator node: (specify the unique cookie for the mediator, the example uses ecss-mediator-example)

    In a cluster configuration, nodes of the similar type should have the same cookies.

    ecss-mediator-example (needs to be entered)

    Cookie for the pa-sip node: (specify the unique cookie for the pa-sip, the example uses ecss-pa-sip-example)

    In a cluster configuration, nodes of the similar type should have the same cookies.

    ecss-pa-sip-example (needs to be entered)

    Cookie for the mycelium node: (specify the unique cookie for the mycelium, the example uses ecss-mycelium-example)

    In a cluster configuration, nodes of the similar type should have the same cookies.

    ecss-mycelium-example (needs to be entered)

    Accept all configuration file changes


  8. Enable SSW services: 
    sudo systemctl unmask ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip

    sudo systemctl enable ecss-ds ecss-mycelium ecss-mediator ecss-core ecss-pa-sip

    Before starting the SSW nodes, change thename of the cluster to the name specified for the ecss2 server (in step 3.4). To do that, in the /etc/ecss/ecss-mycelium/mycelium.config file change the line "{cluster_name, 'eltex.test'}," to "{cluster_name, 'eltex1.test'}," for example.

    sudo nano /etc/ecss/ecss-mycelium/mycelium.config
    [
        {mycelium_broker, [
            {cluster_name, 'eltex1.test'},
            {compress_module, elx_data_nif},
            {session_gc_timeout, 3000},
            {queue_gc_timeout, infinity}
    . . .


  9. Launch mycelium service on ecss1 and use CoCon to make sure that the service is up and mycelium nodes of the ecss1 and ecss2 hosts are visible:
    sudo systemctl start ecss-mycelium

    /system-status

  12. Enable the keepalived service.
    sudo systemctl enable --now keepalived
  13. Configure the SSW connection to the License Provider using the following command in CoCon (in this example, the License Provider is installed in a cluster, and the host IP addresses are 10.0.10.51 and 10.0.10.52, The default port value from the/etc/ecss/ecss-license-provider/config.env file is 4321)

    /system/licence/manager/set --hosts [https://10.0.10.51:4321, https://10.0.10.52:4321]

    After execution, check the connection status with the following command:

    /system/licence/manager/show-status           
    ┌───────────────────────┬───────┬─────┐
    │         Host          │Current│Alive│

    │https://10.0.10.52:4321│       │true │
    └───────────────────────┴───────┴─────┘

    All hosts must have a status of alive=true. One must be “current.” 

    • Current - indicates which host the SSW is connected to. If there is a connection, * is displayed; if not, nothing is displayed.
    • Alive - displays the host’s availability status (healthcheck).

    A lack of connection to the License Provider or ELM is equivalent to a lack of access to the token, which will lead to critical failures and a transition to emergency mode; after a certain period, if the connection is not restored, the system will switch to the Default license.

    This behavior applies only when operating in ELM mode.

    If the status for one of the License Provider hosts is shown as “current,” you can send a request to upload the license to the SSW using the following command:

    /cluster/storage/ds1/licence/request
    /cluster/storage/ds1/licence/request      
    Licence received      
    [*******                                                               ] 6s 2ms
