6 Monitoring and maintaining the system

This chapter provides information and instructions for monitoring and maintaining the Business
Copy 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 monitoring the
following:
Pair status. Status definitions are included.
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 system, with remaining license capacity
A pair's history of operations

Monitoring pair activity, status

Monitoring the Business Copy 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 Remote Web Console 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.
To monitor pair status:
1. In Remote Web Console, click Actions > Local Copy > Business Copy/Snapshot > 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. See
volume details" (page 38)

Description
The volume is not assigned to a pair. The system accepts read/write for SMPL
volumes that are not reserved.
The paircreate operation has begun, the initial copy is in progress.* The system
continues to accept read/write to the P-VOL, but stops write operations to the
S-VOL. No update copy operations are performed.
The initial copy operation is complete, the volumes are paired. The system begins
update copy operations from P-VOL to S-VOL as needed. The P-VOL and S-VOL
in PAIR status may not be identical.
