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.

Procedure

  1. In the Explorer pane, expand the Storage Systems tree.

  2. Expand the target storage system tree, expand Replication, and click Remote Replication.

  3. In the UR Pairs tab, select the pair that you want to monitor.

  4. Click More Actions View Pair Properties.

  5. In the View Pair Properties window, you can display only the columns you want to see by clicking Filter. Click File/Refresh as needed to display the most current information.

  6. To review license capacity, see the Summary area in the Replication window.
