5.9.2 Deletion Procedure

To delete the cluster environment, use the following procedure:

  1. Delete the node.

    Use the Web GUI of the AdvancedCopy Manager to delete the node.

  2. Stop the Resource Group.

    Stop the transaction that is to be deleted by using the High Availability Cluster Multi-Processing function.

    Please refer to High Availability Cluster Multi-Processing User's Guide for information about the method of stopping a resource group.

  3. Delete resources.

    Use the High Availability Cluster Multi-Processing function to delete the AdvancedCopy Manager resources registered for the target transaction. If Resource Groups have been created using only AdvancedCopy Manager resources, delete the whole Resource Group.

    Please refer to High Availability Cluster Multi-Processing User's Guide for information about the method of deletion of a user resource group and a resource.

    Note

    If the system is the 1:1 standby system, the Mutual standby system or the n:1 standby system, proceed to step 9.

    If the system is Cascade topology, proceed to step 4.

  4. Mount the shared disk on the secondary node B.

    Mount the shared disk for shared data on the secondary node B.

    Note

    When there are two or more secondary nodes B, Step 4 to Step 8 is processed by all the secondary nodes B.

  5. Execute the cluster unsetup command on the secondary node B.

    On the secondary node B, execute the following command after blocking other users from accessing the shared disk for shared data:

    [Input example]

    # /opt/swstorage/bin/stgclunset_hacmp -n nodeagt

    Refer to "8.3.8 stgclunset_hacmp (AIX edition High Availability Cluster Multi-Processing environment cancel command)" for command details.

  6. Check the objects to be deleted.

    Information about the logical node specified by the command is displayed. Confirm the displayed information, and press the Enter key.

    # /opt/swstorage/bin/stgclunset_hacmp -n nodeagt

    #

    Note

    In secondary node B, a completion message is swstf8143.

  8. Dismount the shared disk on the secondary node B.

    Dismount the shared disk for share data on the secondary node B.

    Note

    If there are any remaining secondary nodes B that have not performed Step 4 to Step 8, perform from Step 4 in the nodes. When operation from Step 4 to Step 8 is completed by all secondary nodes B, go to Step 9.

  9. Mount the shared disk on the secondary node A.

    Mount the shared disk for shared data on the secondary node A.
