5 Monitoring and maintenance
This chapter provides information and instructions for monitoring and maintaining an ESAM system.
Monitoring pair status
Monitoring the ESAM 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 PAIR status, or that differential
data management is performed in the Split status.
Monitoring using the GUI is done manually and should be repeated frequently. Email notifications
of problems can be set up using the GUI.
Procedure 15 To monitor pair status:
1. In Remote Web Console, click Actions > Remote Copy > Continuous Access Synchronous >
Pair Operation.
2. In the Pair Operation window tree, select the CU group, CU, port, or the host group where
the ESAM pair belongs.
The list displays Continuous Access Synchronous and ESAM pairs. Confirm ESAM on the Type
column to specify the ESAM pair. You can filter the list to display only ESAM pairs by using
Display Filter window.
3. Review pair status in the Status column.
•
The Sync. column shows the percentage of synchronization.
•
You can view more details for the pair in the Detailed Information dialog box.
Procedure 16 To view more information about ESAM pairs:
