This section describes the procedure for verifying the configuration by using a REST API/CLI to obtain respective component information.

  1. Log in to the controller node.
  2. Change the password of the user created in the "ServiceAdministrators" user group, according to the procedure described in Creating an initial user. The parameters and values required to change the password are as follows:

    • userId: ID of the user created in the "ServiceAdministrators" user group

    • currentPassword: Password used when the user was created

    • newPassword: New password

    REST API: PATCH /v1/objects/users/<userId>/password

    CLI: user_password_set

    In the following steps, use the same credentials as in step 2.

  3. Obtain a list of event logs and verify that startup of the storage cluster is completed before confirming configuration.

    REST API: GET /v1/objects/event-logs

    CLI: event_log_list

    If the KARS08100-I message has been output to the event log, startup of the storage cluster is completed. Perform the following procedures to confirm each configuration.

  4. Obtain compute port information, and then verify the configuration.

    REST API: GET /v1/objects/ports

    CLI: port_list

    Confirm the obtained information to verify the following:

    Obtained information

    Verification

    Number of portSummary objects

    • The number must be the same as the number of storage nodes set for numberOfNodes in step 6 of Configuring a storage cluster.
