2. Verify the reversal of volume group roles.
a. Issue the showrcopy command on the failover system (System1).
b. In the Group Information area, check that the Role column for the reversed volume group
displays Primary-Rev (primary as a result of reversal).
For example, the showrcopy output on System1 shows that the role of
periodic_group_1.r96 is now Primary-Rev:
