Mount a backup
You can mount a datastore from a backup if you want to access files in the backup. You can either mount the backup to the same ESXi host where the backup was created or to an alternate ESXi host that has the same type of VM and host configurations. You can mount a datastore multiple times on a host.
Ensure alternate ESXi host can connect to the storage
If you want to mount to an alternate ESXi host, you must ensure that the alternate ESXi host can connect to the storage and has the following:
Same UID and GID as that of the original host
Same virtual appliance for SnapCenter Plug-in for VMware vSphere version as that of original host
Map storage initiators to ESXi
Ensure that the initiators for the storage system are mapped to the ESXi.
Clean up stale LUNs
Because the ESXi can only discover one unique LUN per datastore, the operation will fail if it finds more than one. This can occur if you start a mount operation before a previous mount operation has finished, or if you manually clone LUNs, or if clones are not deleted from storage during an unmount operation. To avoid discovery of multiple clones, you should clean up all stale LUNs on the storage.
A mount operation might fail if the storage tier of the FabricPool where the datastore is located is unavailable.
In the VMware vSphere web client, click Menu in the toolbar, and then select Storage from the drop-down list.
Right-click a datastore and select NetApp SnapCenter in the drop-down list, and then select Mount Backup in the secondary drop-down list.
On the Mount Datastore page, select a backup and a backup location (primary or secondary), and then click Finish.
Optional: To verify that the datastore is mounted, perform the following:
Click Menu in the toolbar, and then select Storage from the drop-down list.
The left Navigator pane displays the datastore you mounted at the top of the list.
If you perform an attach or mount operation on a SnapVault destination volume that is protected by SnapVault schedules and is running ONTAP 8.3, you might see an extra Snapshot copy listed in the attach or mount dialog screen. This occurs because the attach or mount operation clones the SnapVault destination volume and ONTAP updates the volume by creating a new Snapshot copy.
To prevent new Snapshot copies from being created when you clone the volume, turn off the ONTAP schedule for the SnapVault volume. Previously existing Snapshot copies are not deleted.
