Table 5-4 Remote Copy I/O Statistics
Statistic
[1] Description
RIO count
All RIO count Total number of remote I/Os.
All write count Total number of remote write I/Os.
RIO error count Number of errors that occur during remote I/O
Initial copy
Initial copy RIO count Number of initial copy remote I/Os.
Average transfer rate (kB/s) Average transfer rate (kB/sec) for initial copy remote I/Os.
Average response (ms) Average response time (msec) for initial copy remote I/Os.
Update copy
Update copy RIO count Number of update copy remote I/Os.
Average transfer rate (kB/s) Average transfer rate (kB/sec) for update copy remote I/Os.
Average response (ms) Average response time (msec) for update copy remote I/Os.
Asynchronous Copy
Asynchronous RIO count Number of asynchronous update copy remote I/Os.
Total number of recordsets Number of asynchronous recordsets.
Average transfer rate (kB/s) Average transfer rate (kB/sec) for TrueCopy/TCz Async update copy remote I/Os.
Average response (ms) Average response time (msec) for asynchronous update copy remote I/Os.
Number of Scheduling
Recordsets
Number of recordsets that are scheduled for the settlement of sidefile
Scheduling Miss Count Number of times recordsets do not arrive during the schedule
Number of Remaining
Recordsets
Number of remaining recordsets when the schedule is completed
Scheduling Attempt Count Number of job activations of consistency manager
Synchronization
[2]
Pair Synchronized (%) Percent completion of initial copy operations (i.e., number of synchronized pairs /
total number of pairs).
Out of Sync Tracks Number of tracks that have not yet been copied by the initial copy or resync copy
operation (this applies only when suspended during initial copy or during resync
copy).
Cache
Sidefile usage ratio (%)
SideFile
Note: You can select only when you select Device Total or CLPR in the Select
Device on the Display Item dialog box.
Notes:
1. The RIO statistics include both TrueCopy for z/OS and TrueCopy remote
copy operations (e.g., Async RIO Count = TCzA RIOs + TCA RIOs).
2. The Synchronization data cannot be displayed for pairs which were
created by the previous version of TrueCopy for z/OS (0 is always displayed).
