E Monitoring and maintaining the system (secondary
window)
This appendix provides information and instructions for monitoring and maintaining the BC system
using the previous RWC GUI, which opens in a secondary window.
Monitoring the system (secondary window)
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 monitoring the
following:
•
Pair status.
•
Pair and pair volume details.
•
Status and other pair information for pairs in a consistency group.
•
S-VOL path information.
•
Number of pairs in the storage system, with remaining license capacity.
•
A pair’s history of operations.
Monitoring pair activity, status (secondary window)
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 using the RWC GUI is done at the user’s discretion. Monitoring should be repeated
frequently. Email notifications of problems in pair operations can be set up using the GUI.
1.
In RWC, click Actions > Local Replications > BC/SS > Pair Operation.
2. Locate the pair whose status you want to review. Review pair status in the Status column.
You can view more details for the pair by right-clicking and selecting Detail. For more information
about the fields, see
