Table 17 Remote copy I/O statistics
Statistic Description
RIO count
All RIO count Total number of remote I/Os.
All read count Total number of remote read I/Os.
All write count Total number of remote write I/Os.
Initial copy
Initial copy RIO count Number of initial copy remote I/Os.
Initial copy hit count Number of initial copy hits.
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.
Migration Copy
Migration copy RIO count Number of migration copy remote I/Os.
Migration copy hit count Number of migration copy hits.
Update Copy
Update copy RIO count Number of update copy remote I/Os.
Update copy hit count Number of update copy hits.
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.
Restore Copy
Restore copy RIO count Number of restore copy remote I/Os.
Restore copy hit count Number of restore copy hits.
Asynchronous Copy
Asynchronous RIO count Number of asynchronous update copy remote I/Os.
Total number of recordsets Number of asynchronous recordsets.
RCU command retries Number of command retries due to RCU channel-command-retry messages.
MCU command retries Number of command retries due to MCU state-change-pending (SCP) messages.
Average transfer rate (kB/s) Average transfer rate (kB/sec) for Continuous Access XP Async update copy
remote I/Os.
Average RIO response (ms) (Total RIO process time on subsystem or selected volume for a certain interval
period) / (Asynchronous RIO count); where RIO process time = time between
async data transfer request and actual transfer of the recordsets to the RCU.
Synchronization
Pair Synchronized (%) Percent completion of initial copy operations. For example, number of
synchronized pairs/total number of pairs.
Out of Sync Tracks Number of tracks that have not yet been copied by initial copy or resync copy
operations. This applies only when suspended during initial copy or during
resync copy.
