Statistics for lunpaths
Similar to LUNs, lunpaths statistics can be divided into 3 categories: generic statistics, I/O transfer
statistics and class driver specific statistics. Class driver specific statistics depend on the class of the
LUN and require a plug-in module to be displayed.
The following is a sample of lunpath statistics:
# scsimgr get_stat -C lunpath -I 27
STATISTICS FOR LUN path : lunpath27
Generic Statistics:
Attempted class driver opens = 114
Successfull class driver opens = 114
Class driver closes = 114
Offline events = 0
Online events = 0
SPOC state: Active = 114
SPOC state Standby = 0
SPOC state: Failed = 0
SPOC state: Authentication Failure = 0
SPOC state : Disabled = 0
Open failures due to suspended LUN path = 0
LUN resets issued = 0
Last time cleared = N/A
I/O transfer Statistics:
Bytes read = 53248433404
Bytes written = 68912558080
Total I/Os processed = 8260955
I/O failures = 0
Retried I/Os = 32512
Retried I/O failures = 0
I/O failures due to invalid IO size = 0
I/Os flushed = 0
Check condition status = 1
Busy status = 0
Queue full status = 32511
Driver esdisk Statistics :
PR registrations = 0
Activations = 0
Disable requests = 2
Enable requests = 1
Last time cleared = N/A
Sample of a target path statistics
Target path statistics can be divided into 3 categories:
• Generic statistics: They are commonly defined for all target paths independent of the SCSI
transport. They are maintained by the SCSI services module.
• Interface driver (I/F) common statistics: They are commonly defined for all target paths
independent of the SCSI transport. They are maintained by each interface driver.
• Interface driver (I/F) specific statistics: They are maintained by interface drivers and depend
on the type of the SCSI transport. They require a plug-in module to be displayed. Currently no
interface driver provides a plug-in module for scsimgr. Therefore scsimgr does not
display interface driver specific statistics.
