Removing Snapshots - Dell EMC VxFlex Ready Node User Manual

Removing snapshots

Removing snapshots from a consistency group
About this task
You can remove a volume together with its snapshots, or remove individual snapshots.
Before removing a volume or snapshots, you must ensure that they are not mapped to
any SDCs. If they are, unmap them before removing them. Snapshots are unmapped in
the same way as volumes are unmapped. For information, see
page 219.
Best practice is to avoid deleting volumes or snapshots while the MDM cluster is being
upgraded, to avoid causing a Data Unavailability status.
Note: Removal of a volume or snapshot erases all the data on the corresponding
volume or snapshot.
