To delete the cluster environment, use the following procedure:
Delete the node.
Use the AdvancedCopy Manager command to delete the node.
Stop the transaction.
Stop the transaction to be deleted using the High Availability Cluster Multi-Processing function.
Refer to "High Availability Cluster Multi-Processing User's Guide" for stopping a Resource Group.
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.
Refer to "High Availability Cluster Multi-Processing User's Guide" for deleting a user resource group and a resource.
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.
Mount the shared disk on the secondary node B.
Mount the shared disk for AdvancedCopy Manager shared data on the secondary node B.
Note
When there are two or more secondary nodes B, perform step 4 to step 8 for all of these nodes.
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 AdvancedCopy Manager shared data:
Example:
# /opt/swstorage/bin/stgclunset_hacmp -n nodeagt |
Refer to "16.3.3 stgclunset_hacmp (AIX version High Availability Cluster Multi-Processing environment cancel command)" for command details.
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

Do you want to continue with un-setting of AdvancedCopy Manager cluster? [default:y] |
To interrupt cluster environmental unsetup processing, input "n". To continue processing, input "y", or press the Enter key.
Note
The number of nodes that are not carrying out cluster unsetup command is output to "Number". For a secondary node B, it must be three or more.
The cluster unsetup command is executed on the secondary node B.
The window indicating cluster unsetup command completion opens.
swstf8143 The cluster deletion of the secondary node has been completed. Next, delete the cluster environment of the other secondary node. # |
Note
For secondary node B, a completion message is swstf8143.
Dismount the shared disk on the secondary node B.
Dismount the shared disk for AdvancedCopy Manager shared 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 on the nodes. When operation from step 4 to step 8 is completed by all secondary nodes B, go to step 9.
Mount the shared disk on the secondary node A.
Mount the shared disk for AdvancedCopy Manager shared data on the secondary node A.
Execute the cluster unsetup command on the secondary node A.
On the secondary node A, execute the following command after blocking other users from accessing the shared disk for AdvancedCopy Manager shared data:
Example:
# /opt/swstorage/bin/stgclunset_hacmp -n nodeagt |
Refer to "16.3.3 stgclunset_hacmp (AIX version High Availability Cluster Multi-Processing environment cancel command)" for command details.
