Cannot select the desired volumes when creating a copy set
This condition occurs when you create a copy set.
Problem
Each volume in a copy set must be of the same size and machine type. If the volume size and type do not match, then the volumes cannot be paired in the copy set. Non-matching volumes are not included in the pull-down list of eligible volumes.
Action
Ensure that the size and type of each volume are the same using the lsvol -l command.
