Mounting a NetApp snapshot

Snapshot copies enable system administrators to perform the following tasks:

• Create instantaneous backups
• Create a clone of a FlexVol volume
• Create a clone of a Data ONTAP LUN
• When the time comes and you need to mount a snap shot to recover a lost file then you will need to perform the following steps from the cluster shell.

Look for the snapshot you will want to recover with the following command.

snap list -volume vol_ds_videos -fields snapshot,create-time

The output will look like this:

nac01-lax::> snap list -volume vol_ds_videos -fields snapshot,create-time
vserver volume snapshot create-time

Clone the snapshot you would like to recover with the following command.
Make sure you change the parent-volume with volume from the previous command. Also change flex-clone name with the same name as parent-volume plus a -clone at the end.
Finally ensure you change the parent-snapshot with the snapshot name from the previous command you would like to recover.

vol clone create -vserver esxi01-lax -flexclone vol_ds_videos_clone -type RW -parent-volume vol_ds_videos -junction-active true -foreground true -parent-snapshot smvi_videos-monthly-3M-retention_novmsnap_20170201233001

Mount the volume with the junction path.

volume mount -vserver esxi01-lax -volume vol_ds_videos_clone -junction-path /vol_ds_videos_clone

Finally mount the volume on the esxi server you want using the LIF IP of the SVM via vcenter as a data store.
