F Monitoring and maintaining the system (secondary
window)
This appendix provides information and instructions for monitoring and maintaining the BC Z
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.
•
T-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 Z 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 the RWC, click Actions > Local Replications > BC Z/FC Z > 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
“Reviewing pair, volume details” (page 137) .
Pair status definitions (secondary window)
When checking your pairs’ status in the RWC secondary window, click Refresh View to make sure
pair data is current.
See the following topics related to pair status:
•
“Pair status definitions” (page 50) .
•
“Status, pair operations permitted ” (page 51) .
•
“Status of unaffected S-VOLs, operations permitted ” (page 52) .
Reviewing pair, volume details
You can review the data related to pairs and their volumes. This includes volume capacity, pair
status, S-VOL and T-VOL identifiers, and several other details.
NOTE: LDEVs for S-VOLs and T-VOLs listed In the RWC may end in the following special symbols:
•
A pound or gate symbol (#), which indicates an external volume (for example, 00:00:01#).
1. In the RWC, click Actions > Local Replications > BC Z/FC Z > Pair Operation.
2. In the tree, select the CU image where the pairs or volumes are located. Related volumes are
shown in the volume list.
