volume, a snapshot repository volume, a snapshot volume, a base volume of an active snapshot volume, a Snapshot Volume (snapshot-image based), a thin volume, a source volume in a copy pair that i
s currently Pending, In Progress, or Failed, or is the same volume that you entered as the source volume for this copy pair. Please select a different target volume (Standard volume) and then ret
ry the operation.
The command at line 1 that caused the error is:
