To delete the cluster environment, use the following procedure:
Delete the node.
Use the Web GUI of the AdvancedCopy Manager to delete the node. For a Storage Management Server transaction, however, this operation is not necessary.
Stop the cluster service (userApplication).
Use the SynfinityCluster management view or the RMS main window of PRIMECLUSTER to stop the transaction to be deleted.
Delete the resources.
In SynfinityCluster, use the SynfinityCluster management view to delete the AdvancedCopy Manager resources registered for the target transaction. If cluster service has been created using only AdvancedCopy Manager resources, delete the whole cluster service.
In PRIMECLUSTER, use the PRIMECLUSTER "userApplication Configuration Wizard" to delete the AdvancedCopy Manager resources registered for the target transaction. If userApplication has been created using only AdvancedCopy Manager resources, delete the whole userApplication.
Note
If the system is the 1:1 standby system, the Mutual standby system or the n:1 standby system, proceed to step 10.
If the system is the Cascade topology or the Priority transfer, 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.
For a Storage Management Server transaction, also mount the shared disk for the repository in the secondary node B.
Note
When there are two or more secondary nodes B, Step 4 to Step 9 is processed by all the secondary nodes B.
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_safe -n nodeMGR |
Refer to "8.3.1 stgclunset_safe (Solaris edition SafeCLUSTER/PRIMECLUSTER environment cancel command)" for command details.
Note
For a Storage Management Server transaction to be performed, use the location that was specified when the Storage Management Server was installed.
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_safe -n nodeMGR

Dismount the shared disk for share data on the secondary node B.
For a Storage Management Server transaction, also dismount the shared disk for the repository on the secondary node B.
Note
If there are remaining secondary nodes B for which steps 4 to 9 have not been performed, perform from Step 4 in the nodes.
When operation from Step 4 to Step 9 is completed by all secondary nodes B, go to Step 10.
