8 Monitoring the system
Monitoring pairs, journals, and data paths should be checked frequently to insure that Continuous
Access Journal Z pairs are operating correctly. Pair status should be checked before performing
a Continuous Access Journal Z operation. Each operation requires specific pair status.
Monitor pair activity, status
Monitoring the Continuous Access Journal Z system is an ongoing operation that should be
performed frequently to maintain your pairs.
•
When you want to perform a pair command, first check the pair’s status. Each operation
requires a specific status or statuses.
•
Pair-status changes when an operation is performed. Check status to see that pairs are operating
correctly and that data is updated from P-VOLs to S-VOLs in the Paired status, or that differential
data management is performed in the Split status.
Monitoring using the Remote Web console GUI is done at the user’s discretion. Monitoring should
be repeated frequently. Email notifications of problems can be set up using the GUI.
