Disabling high availability functions is a maintenance task that deletes the system configurations used for high availability functions.
Certain functions must be performed in tools other than Ops Center Administrator:
- Replication removal:
Replications created from the S-VOL of the HA pairs, including any local or remote replications, must be deleted or HA pair deletion will fail.
- Stopping an OS or application:
In many cases the S-VOL must be disconnected before unprovisioning. If necessary, stop the OS or application.
The P-VOL is not changed, so the OS or application using the P-VOL should not be stopped.
- The dummy host group created by Ops Center Protector cannot be deleted in Ops Center Administrator.
- Notes regarding unprotecting volumes:
- After removing protection by high availability set to a primary volume, all LUN paths for a secondary volume are deleted. A host group for the LUN path that is created by Ops Center Administrator is deleted when the host group has no LUN path. The dummy host group that is created by Ops Center Protector is not deleted. You can delete it with other storage management software as needed.
- Notes regarding replication group deletion:
- After deleting a replication group whose replication type is high availability, all LUN paths for secondary volumes in the replication group are deleted. A host group for the LUN path that is created by Ops Center Administrator is deleted when the host group has no LUN path. The dummy host group that is created by Ops Center Protector is not deleted. You can delete it with other storage management software as needed.
- Notes regarding primary volume removal from a replication group:
- After removing primary volumes from a replication group whose replication type is high availability, all LUN paths for secondary volumes paired with the removed primary volumes in the replication group are deleted. A host group for the LUN path that is created by Ops Center Administrator is deleted when the host group doesn't have LUN path. The dummy host group that is created by Ops Center Protector is not deleted. You can delete it with other storage management software as needed. Note: To unprotect a volume which is also the primary volume in another high availability pair (Optionally, deleting the replication group), Ops Center Protector v7.5.2 or later needs to be registered.
