To delete the cluster environment, use the following procedure:
Delete the node.
Use the Web GUI of the AdvancedCopy Manager to delete the node.
Stop the transaction.
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 |
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 |
Mount the shared disk on the secondary node.
Mount the shared disk for AdvancedCopy Manager shared data on the secondary node.
Execute the cluster unsetup command on the secondary node.
On the secondary node, execute the following command after blocking other users from accessing the shared disk for AdvancedCopy Manager shared data:
[Input example]
# /opt/swstorage/bin/stgclunset_aixvcs -n nodeagt |
Refer to "8.3.7 stgclunset_aixvcs (AIX edition VERITAS Cluster Server 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_aixvcs -n nodeagt
AdvancedCopy Manager settings were as follows.
Cluster system : VERITAS Cluster Server
Node type : Secondary
Mount point : /STGMGRDISK
Node name : nodeagt
Service : STGMGRSRV
Function : Server
Number : 2
MODE : Normal
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 outputted to "Number". In a secondary node, it is likely to be two.
The cluster unsetup command is executed on the secondary node.
The window indicating cluster unsetup command completion opens.
swstf8103 The cluster deletion of the secondary node has been completed. Next, delete the cluster environment of the primary node. # |
Dismount the shared disk on the secondary node.
Dismount the shared disk for AdvancedCopy Manager shared data on the secondary node.
Mount the shared disk on the primary node.
Mount the shared disk for AdvancedCopy Manager shared data on the primary node.
Execute the cluster unsetup command on the primary node.
On the primary node, execute the following command after blocking other users from accessing the shared disk for AdvancedCopy Manager shared data:
[Input example]
# /opt/swstorage/bin/stgclunset_aixvcs -n nodeagt |
Refer to "8.3.7 stgclunset_aixvcs (AIX edition VERITAS Cluster Server 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_aixvcs -n nodeagt
AdvancedCopy Manager settings were as follows.
Cluster system : VERITAS Cluster Server
Node type : Primary
Mount point : /STGMGRMNT
Node name : nodeagt
Service : STGMGRSRV
Function : Server
Number : 1
MODE : Normal
Do you want to continue with un-setting of AdvancedCopy Manager cluster? [default:y] |
To interrupt cluster environmental unsetup processing, input "n". To continuing processing, input "y", or press the Enter key.
Note
The number of nodes that are not carrying out cluster unsetup command is outputted to "Number". In a primary node, it will be set to 1.
The cluster unsetup command is executed on the primary node.
The window indicating cluster unsetup command completion opens.
swstf8102 The cluster deletion of the primary node has been completed. # |
Dismount the shared disk on the primary node.
Dismount the shared disk for AdvancedCopy Manager shared data on the primary node.
Delete port numbers.
Delete the following services defined in /etc/services during cluster setup. Delete the services on the primary node and the secondary node. Use an OS command such as vi to delete the service from /etc/services.
Communication daemon for transactions: stgxfws_Logical-Node-Name
Start the transaction.
The function of VERITAS Cluster Server is used to start the transaction stopped in step 2. This operation is not necessary if the Service Group was deleted in step 3.
Please refer to VERITAS Cluster Server User's Guide about the method of starting a user service group.
# hagrp -online User-Service-Group -sys system-name |
system-name: The node name where the user service group is to be started
