Cannot protect a volume
This condition occurs when attempting to change the protection settings for a volume.
Problem
You must have Administrator privileges to change volume protection settings. You cannot change volume protection settings for a volume that is part of a copy set in a session.
Action
Verify that you are logged in as Administrator and that the volume is not already in a session.
To check if a volume is in a Resource Group, use the DSCLI command lsresgrp to display resource groups for a specific DS8000 storage subsystem. See https://www.ibm.com/support/knowledgecenter/en/SSHGBU for information on the lsresgrp command.
