5 Monitoring and maintenance
This topic provides information and instructions for monitoring and maintaining the FS system.
Monitoring pair information
You can monitor pair information in the following ways:
•
“Viewing the number of pairs and a list of pairs” (page 51) .
•
“Monitoring pair properties” (page 51) .
•
“Monitoring synchronous rates” (page 52) .
Viewing the number of pairs and a list of pairs
1. In the Storage Systems tree, click Replications > Local Replications.
2. View the number of pairs and a list of pairs.
Pair status definitions
When checking the pair status, click Refresh View to ensure the data is current.
The following table shows the FS pair status definitions.

PSUS for P-VOLs Read/Write
enabled. Can be
mounted. The pairsplit command has completed. Update copy operations
are stopped. S-VOLs accept read/write operations. The system records
differential data between the P-VOL and S-VOLs so that you can
immediately resynchronize the pair. PSUS
SSUS for S-VOLs
RCPY Read/write
disabled A reverse resync operation is in progress. S-VOLs do not accept
read/write operations. Only S-VOL differential data is copied to the RCPY
P-VOL. Update copy operations are not performed during Reverse
