raidar
Report LDEV activity
Description
The raidar command reports the I/O activity of a port, target or LUN over
a specified time interval. It will report any early termination via CNTL-C.
This command can be used regardless of the RM instance configuration
definitions.
I/O activity of an S-VOL that is part of an active CA pair (a pair that is in
the COPY or PAIR state) shows internal I/O used to maintain the pair as
well as user I/O. For BC, only host I/Os are reported on the P-VOL.
For CA, the I/O activity reported for an S-VOL in either COPY or PAIR
state reflects the total, not just host based, activity of the volume.
For BC, only the host based I/O activity is reported.
If the volume state changes from S-VOL (COPY or PAIR) to SMPL during
the monitoring period, the activity number may be based on some internal
and some host I/Os.
