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 Service Group.
Stop the transaction to be deleted by using the VERITAS Cluster Server function.
Please refer to VERITAS Cluster Server User's Guide for information about the method of stopping a user service group.
An example of stopping the user service group by the command of VERITAS Cluster Server is as follows.
In this example, a User Service Group name is set to "STGMGRSRV", and an active system node name is set to "node1".
# hagrp -offline STGMGRSRV -sys node1 |
Delete resources.
Use the VERITAS Cluster Server function to delete the AdvancedCopy Manager resources registered for the target transaction. If Service Groups have been created using only AdvancedCopy Manager resources, delete the whole Service Group.
Please refer to VERITAS Cluster Server User's Guide for information about the method of deleting a user service group and a resource.
The user service group by the command of VERITAS Cluster Server and the example of deletion of a resource are as follows.
In this example, a user service group name is set to "STGMGRSRV".
Moreover, each resource name is carried out as follows.
Resource name (Application): AdvancedCopy_Manager_appl
Resource name (MountPoint of the shared disk for AdvancedCopy Manager share data): AdvancedCopy_Manager_mount
Resource name (MountPoint for AdvancedCopy Manager RIPOJITORI): AdvancedCopy_Manager_DB
The resource concerned exists only on Storage Management Server business.
Resource (name IP):sybase_ip
VCS config table is saved by another file-name.
# mv /etc/VRTSvcs/conf/config/main.cf /etc/VRTSvcs/conf/config/main.cf.bk |
Place VCS into the read-write enabled state.
# haconf -makerw |
Delete a resource (Application, MountPoint).
# hares -delete AdvancedCopy_Manager_appl # hares -delete AdvancedCopy_Manager_mount # hares -delete AdvancedCopy_Manager_DB |
A resource (IP) is deleted when not using it in a transaction.
# hares -delete sybase_ip |
When deleting a transaction, a user service group is deleted.
# hagrp -delete STGMGRSRV |
Reflect the VCS setting and set VCS into the read-only mode.
# haconf -dump -makero |
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 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.
For a Storage Management Server transaction, also mount the repository shared disk 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_vcs -n nodeMGR |
Refer to "8.3.2 stgclunset_vcs (Solaris version VERITAS Cluster Server 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_vcs -n nodeMGR
