Synchronization [2]
For initial copy operations, the percentage of pairs synchronized out
of the total number of pairs
Pair Synchronized
Number of tracks that have not yet been copied by the initial or resync
copy operation
Out of Synchronous Tracks
(1) The RIO statistics are included for Continuous Access Synchronous and Cnt Ac-S Z operations, if present.
(2) Synchronization data cannot be displayed for pairs created with the previous version of Continuous Access
Synchronous. “0” displays in this case.
7. Click Set to close the Display Item dialog box. The Usage Monitor window now shows a graph
of the selected I/O statistics data for the selected LU(s).
Resize graph, save data
• To enlarge the graph, right-click it and select Large Size.
• To close the graph, right-click it and select Close.
• To save monitoring data in text files, use the Performance Monitor Export Tool.
Monitor, maintain logical paths
Check logical path status to keep track of and maintain paths.
Procedure 13 To monitor logical path status
1. On the menu bar, click Actions > Remote Copy > Continuous Access Synchronous > RCU
Operation. The RCU Operation window opens.
2. Select MCU&RCU in the Display box.
3. Select the RCU you want, right-click, then click RCU Status. The RCU Status dialog box displays.
Logical path status definitions
Status descriptions are provided below. Click File/Refresh to make sure data is current.
Table 27 Logical path status definitions
DescriptionStatus
This path has been successfully established and can be used for Continuous Access
Synchronous remote copy activities.
Normal
The link initialization procedure with the secondary system has failed, because the physical
path connection between either the primary and secondary systems, or between the primary
system and the host, was missing.
Initialization Failed
A timeout error has occurred between the primary and secondary systems.Communication Timeout
The logical path link function has been rejected by the secondary system. All logical path
resources in the secondary system might be used for other connections.
Path Rejected
