Options for Unmounting and Logging Off a Smart Copy
When you have mounted a Smart Copy and you have finished all restoration operations, you can unmount and log off the Smart
Copy. As part of the unmount operation, ASM/ME automatically sets the Smart Copy offline on the PS Series group.
For replica Smart Copies, you have two options for unmounting and logging off a replica:
● Unmount and Logoff—Unmounts, logs off, and demotes the replica set.
● Delete—Unmounts, logs off, and demotes the replica set as necessary. It then deletes the replica unless it is the most recent
replica in the replica set. In the latter case, it is necessary to retain the replica to ensure consistency of the replica set.
Constraints for Unmounting and Logging Off a Smart Copy
The following are constraints for unmounting and logging off a Smart Copy.
● Unmounting and logging off a Smart Copy automatically breaks VSS control of the Smart Copy.
NOTE: You cannot manage the copy by using Microsoft utilities. You must use ASM/ME.
● If the Smart Copy is a snapshot, you can delete the snapshot as part of the unmount and logoff operation.
● If the mounted volume is a snapshot, and additional mounted snapshots from the same Smart Copy exist, the option to
delete the Smart Copy is disabled.
To delete the Smart Copy:
● Unmount and log off all the corresponding volumes.
● Delete the Smart Copy that contains all the volumes.
Prerequisites for Unmounting Smart Copies in a Cluster Environment
The following prerequisites pertain to unmounting Smart Copies in a cluster environment.
● Smart Copies must not be in use.
● Volumes must be put into maintenance mode. If they are cluster resources, use the appropriate procedure depending on the
version of product and server.
● If the unmount and volume deletion is permanent, remove any dependencies on the volumes' physical disk resources and
delete the physical disk resources using the Cluster Administration tools.
● If the unmount and logoff is temporary, remount the volumes, then take them out of maintenance mode.
● The node must own all cluster resources in the cluster resource group.
Unmount and Log Off a Smart Copy
1. From the Volumes node in the tree panel, right-click the mounted Smart Copy and select Unmount and Logoff.
The Unmount and Logoff dialog box opens.
2. (Optional) Select the checkbox for deleting the snapshot from the PS Series group represented by this volume.
Because the selected volume is a mounted snapshot and not a clone, you have the option to select the snapshot for deletion
as soon as it is no longer mounted. Select the checkbox to delete the snapshot.
3. Select Logoff to proceed with the operation.
View Multipath Information
If you have MPIO configured, you can display the multipath information for hosts and host volumes by expanding the MultiPath
node in the tree panel.
The MultiPath screen displays:
