Monitoring pair activity, status, license capacity

Monitoring pairs, journals, data paths, I/O, licensed capacity, and hardware performance is essential for ensuring that Universal Replicator pairs continue to function correctly.

• Before performing a pair operation, check the pair status to verify that the desired operation can be performed. For details about the pair statuses, see Pair status definitions.

• The pair status changes when an operation is performed. If the pair status is PAIR, data update is executed correctly from the P-VOL to the S-VOL. If the pair status is PSUS/PSUE, the pair is split or suspended, and therefore differential data is managed.

Frequent monitoring of the system is recommended but optional. You can set up automatic e-mail notification from Device Manager - Storage Navigator for problems found during monitoring.
