SnapCenter Plug-in for VMware vSphere 5

Unmount a backup

You can unmount a backup when you no longer need to access the files in the datastore.

If a backup is listed as mounted in the VMware vSphere client GUI, but it is not listed in the unmount backup screen, then you need to use the REST API /backup/{backup-Id}/cleanup to clean up the out-of-bound datastores and then try the unmount procedure again.

If you attempt to mount a backup copy of an NFS datastore on a storage VM (SVM) with the root volume in a load-sharing mirror relationship and you might encounter the error You may have reached the maximum number of NFS volumes configured in the vCenter. Check the vSphere Client for any error messages. To prevent this problem, change the maximum volumes setting by navigating to ESX > Manage > Settings > Advance System Settings and changing the NFS.MaxVolumes value. Maximum value is 256.

Steps

In the VMware vSphere client, click Menu in the toolbar, and then select Storage from the drop-down list.
In the left Navigator pane, right-click a datastore, then select SnapCenter in the drop-down list, and then select Unmount in the secondary drop-down list.

Make sure that you select the correct datastore to unmount. Otherwise, you might cause an impact on production work.
In the Unmount Cloned Datastore dialog box, select a datastore, select the Unmount the cloned datastore checkbox, and then click Unmount.
