CAUTION:
Even if you do not change the default settings, go to Volume

Properties
→
Shadow Copies
→
Settings and click OK. Perform this action to
ensure proper snapshot recovery in the event of node failure. When the snapshot
size exceeds the maximum size of the storage area, the oldest snapshot is deleted.
NOTE:
Each volume can have up to 512 snapshots for iSCSI virtual disks,
irrespective of the number of virtual disks created in the volume. Snapshots are
space efficient because they are differential copies.
