6 Monitoring and maintaining the system
This chapter provides information and instructions for monitoring and maintaining the BC system.
Monitoring the system
Monitoring helps you keep track of pairs and volumes and their current and past conditions.
Monitoring should be an ongoing activity. This section provides information for the following:
•
“Monitoring pair activity, status ” (page 53) . Status definitions, permitted operations for each
status, and permitted operations for L1 and L2 pairs are included.
•
“Monitoring pair, volume details” (page 57) .
•
“Monitoring synchronous rates” (page 57) .
•
“Monitoring consistency groups” (page 57) .
•
“Monitoring reserve volumes” (page 58) .
•
“Monitoring a pair’s operation history ” (page 58) .
Monitoring pair activity, status
Monitoring the BC system is necessary to maintain your pairs.
Each operation requires a specific status or statuses. When you want to perform a pair command,
first check the pair’s status.
Pair-status changes when an operation is performed. Check status to see that pairs are operating
correctly and that status is changing to the appropriate state during and after the operation.
Monitoring should be repeated frequently. Email notifications of problems in pair operations can
be set up using RWC.
