6 Monitoring and maintaining the system
This chapter provides information and instructions for monitoring and maintaining the Business
Copy Z 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.
• T-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 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 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.
Procedure 10 To monitor pair status
1. In Remote Web Console, click Actions > Local Copy > Business Copy for Mainframe/Compatible
FlashCopy/Compatible FlashCopy SE > 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 “Reviewing pair,
volume details” (page 44) for field information.
Pair status definitions
Pair status descriptions are provided below. When checking your pairs’ status, click File/Refresh
