Monitoring pair status and license capacity

The following are a couple of examples of when you would check the status of a pair:

• Check the status before performing a pair operation. Each operation requires a specific status or set of statuses.
• Check status to see that pairs are operating correctly and that data is updated from P-VOLs to S-VOLs in PAIR status, or that differential data management is performed in Split status. Pair status changes when an operation is performed.

You can check the TC pair status by HDvM - SN or CCI. Monitoring should be repeated frequently. Email notifications of problems can be set up using HDvM - SN or Maintenance Utility.

To perform this task in CCI, use the pairdisplay command or the pairevtwait command.
