ERRORLEVEL(group_name)

The group_name option allows you to associate any valid TSO name with one or more volume pairs. An error that occurs on a single storage control that attaches to any duplex volume pair that has ERRORLEVEL(group_name) specified causes XRC to suspend all other volume pairs that have been assigned the same group name specification. If the same group_name is used on other sessions that are coupled in the same master session, the volume pairs in the other sessions are not suspended.

Note: Volumes must be in duplex state before an error that is related to the associated volumes can cause other duplexed volumes to become suspended. This prevents the following error conditions for volume pairs that are still in pending state from suspending all volume pairs in the session:

Volume serial numbers entered incorrectly
Track copy errors during volume synchronization
Spurious track errors during volume synchronization

You can diagnose and correct these XADDPAIR command-related errors independently of other XRC session activity. When you have corrected the error, you can make the volume pair operational by reissuing the XADDPAIR command.
