Retrieving Target or LUN Statistics
To display statistics collected for a SCSI object, use the scsimgr get_stat command.
To display statistics for a SCSI controller, use the target as the identifier as follows:
# scsimgr get_stat -H 0/2/1/0.0x500805f300083899
SCSI STATISTICS FOR TARGET PATH : 0/2/1/0.0x500805f300083899
