Sample of a HBA controller statistics
Similar to target paths, SCSI HBA controller statistics can be divided in 3 categories: generic statistics,
I/F common statistics and I/F driver specific statistics.
# scsimgr get_stat -H 0/4/1/0/4/0
SCSI STATISTICS FOR CONTROLLER : 0/4/1/0/4/0
Generic Statistics:
Illegal events = 0
Ctlr Probe events received = 645
BUS Reset events received = 0
BUS Reset event failures = 0
Target path probe failures = 0
Total I/Os processed = 735174372
Last time cleared = N/A
I/F Common Statistics:
Outstanding I/Os = 0
Bytes read = 4670035451002
Bytes written = 6719212338688
Last bus reset time = N/A
Target ports connected = 21
Bus resets attempted = 0
Offline state = 0
Online state = 1
Displaying information about lunpaths of a LUN
The user can display information about lunpaths of LUN by running the scsimgr command as shown
below:
# scsimgr lun_map -D /dev/rdisk/disk20
LUN PATH INFORMATION FOR LUN : /dev/rdisk/disk20
Total number of LUN paths = 2
World Wide Identifier(WWID) = 0x20000020371972eb
