A.4.2 Deletion Procedure

To delete the cluster environment, use the following procedure:

Point

For explanatory purposes, the <Examples of command execution> in this section use the following settings:

  • <Mountpoint-of-shared-disk-for-AdvancedCopy-Manager-shared-data> : /acmdata01

  • Logical node name : acmnode1

  1. Delete the node.

    Use the AdvancedCopy Manager command to delete the node.

  2. Use the function of a clustered system to stop the transaction on the primary node.

    Refer to your cluster software documentation for information on how to stop transactions.

  3. Delete resources.

    Delete the AdvancedCopy Manager resources registered for the target transaction.

    Refer to your cluster software documentation for information on how to delete resources.

  4. If the system is a Cascade topology or a Priority transfer, execute "Deletion procedure for secondary node" on the secondary node B.

  5. Execute "Deletion procedure for secondary node" on the secondary node A.

  6. Execute "Deletion procedure for primary node" on the primary node.

Deletion procedure for secondary node

  1. For Managed Server transactions, mount the shared disk.

    Mount the shared disk for the AdvancedCopy Manager shared data on the secondary node.

  2. Execute the following commands in the given sequence:

    Sequence of execution
