I today realized that Daily Exchange Backup Job left snapshot on 3PAR. I see two snapshots with same timestamp which one is RW and the other is RO. RW snapshot seems to be exported to first node of the Hyper-V Cluster, and the RO is unexported. showvv and showvlun outputs from 3PAR are below.

I have opened a case with ID 01807989. What can be caused this issue? Is it safe to delete these snapshots?
Thanks in advance.
