statistics, you must specify the option "
-d driver" without any SCSI object identifier or
keyword for a group of SCSI objects.
If the identifier
all is specified with
clear_stat, clear_stat clears the statistics
of all SCSI HBA controllers, all target paths, all LUN paths, and all LUNs in the system.
You do not need to use any other identifiers. This operation also resets the global generic
statistics.
Usage:
scsimgr [-v] clear_stat [ identifier |
all_lun | all_ctlr ]
scsimgr [-v] clear_stat identifier {
all_lpt|all_tp}
scsimgr [-v] clear_stat -A alias all_tp
scsimgr [-v] clear_stat all
scsimgr [-v] clear_stat -D leg_dsf
scsimgr [-v] get_stat [ identifier |
all_lun | all_ctlr ]
scsimgr [-v] get_stat identifier {
all_lpt |all_tp}
scsimgr [-v] get_stat -A alias all_tp
scsimgr [-v] get_stat -D leg_dsf
Note: identifier identifies a LUN, LUN path, target path, alias, or SCSI HBA controller.
Alias is a target port alias previously assigned by the
tport_alias attribute of a target
path.
clear_kmstat
The clear_kmstat command clears the kernel metric (Kmetrics) data counters for a
SCSI object
The
-v option with clear_kmstat specifies a verbose output for the execution of the
command. For instance, if executed on a group of objects (for example, all_lun), the
command shows the results for each SCSI object.
Usage:
scsimgr [-v] clear_kmstat identifier | all_lun
scsimgr [-v] clear_kmstat -D leg_dsf
Note: identifier identifies a LUN.
cold_bdr/lun_reset/warm_bdr
Respectively performs the following SCSI task management functions (if supported by
the interface driver):
• TARGET COLD RESET management task sent to the device.
Actions necessary to perform a cold target reset depend on the SCSI transport. In case
of Fibre Channel transports, the target is reset and a TPLO (Third Party Log Out) is
performed.
• LUN RESET management task sent to the device.
• TARGET WARM RESET management task sent to the device.
Usage:
scsimgr [-f] cold_bdr identifier
scsimgr [-f] lun_reset identifier
scsimgr [-f] warm_bdr identifier
Note: identifier identifies only a LUN.
ddr_add/ddr_del
Respectively adds and deletes a settable attribute scope for a driver.
Once a scope is added, it is possible to set specific attribute values at this scope. These
values will affect the default behavior for devices covered by the scope.
It is not necessary to add a scope to be able to display the values of attributes for devices
covered by the scope. The values are inherited from highest scope where the attributes
are explicitly set.
WARNINGS: These commands may affect the interoperability with certain devices or the
proper operation of the system. They should only be used by experienced users. HP
