Client failover

After a failover takes place between a Primary and Passive instance, additional steps are needed for each client.

For each Client instance there are two steps that are required after an Active/Passive failover:
  • If you are using the IBM® shared service for IBM Storage Scale, the IBM shared service for IBM Storage Scale instance must be removed from the cloud group and redeployed.
    1. Do one of the following actions:
      1. Click Patterns > Shared Services.
      2. Click Patterns > Shared Services Instances.
    2. Expand the IBM Shared Service for GPFS node.
    3. Click Delete to delete the deployed instance.
    4. Click Deploy to deploy the shared service again. You will need to specify the IBM Storage Scale Manager IP and Client Key. See the Related links for more information.
  • If you are using the IBM shared service for IBM Storage Scale, the IBM Storage Scale Client must be reconnected to the IBM Storage Scale servers through the shared service.
    1. If you configured your IBM Storage Scale Client to connect to the IBM Storage Scale Server through the IBM Storage Scale Client Policy, select the deployed client instance and from the Manage > Operations > GPFSClient section, run the Connect to Server operation.

      Otherwise, if you configured your IBM Storage Scale Client to connect to the IBM Storage Scale Server by using IBM Storage Scale Client script packages, select the deployed client instance and run the GPFS Client Operations script package, and select to run the Connect to server action, providing an authorized product administrator user name and password.

    2. Repeat this operation for each IBM Storage Scale client in the cloud group.
  • If you specified the IBM Storage Scale server at deployment time or by using the Connect to server operation, the IBM Storage Scale Client must be reconnected to the IBM Storage Scale servers by using the Connect to server operation.

    If the instance uses the IBM Storage Scale client policy, use the Same GPFS server option in the Connect to server operation. For more information, see Connect to Server operation.

    If the instance uses the IBM Storage Scale script packages, use the Same GPFS server option in the Connect to server script package. For more information, see Connecting to a IBM Storage Scale Server that is not specified by the IBM shared service for IBM Storage Scale.
