s
scsictl(1M) scsictl(1M)
-q Suppress the labels that are normally printed when mode parameters are displayed.
Mode parameter values are printed in the same order as they appear on the command
line, separated by semicolon-blank (
; ) or newline.
-t tgtid ctrl
Specify tgtid as the SCSI target parameter on which operation needs to be initiated. The
valid range of tgtid value is between 0 and 15. In agile addressing the tgtid is the
port_id returned by the command
scsimgr get_info -H
target_path . See intro (7)
for information about agile addressing and scsimgr (1M). The commands supported with
the
-t option are domain_val, get_bus_parms
, get_target_parms
,
reset_target and reset_bus. See the -c option for explanations of these com-
mands. ctrl specifies the special file of a parallel SCSI controller node.
RETURN VALUE
scsictl exits with one of the following values:
0 Operation successful.
>0 Error condition occurred.
DIAGNOSTICS
Diagnostic messages are generally self-explanatory.
EXAMPLES
To display all the mode parameters, turn
immediate_report
on, and redisplay the value of
immediate_report:
scsictl -a -m ir=1 -m ir /dev/rdsk/c0t6d0
producing the following output:
immediate_report = 0; queue_depth = 8; immediate_report = 1
The same operation with labels suppressed:
scsictl -aq -m ir=1 -m ir /dev/rdsk/c0t6d0
produces the following output:
0; 8; 1
To clear persistent reservation from a device:
scsictl -p pr_clear key /dev/rdsk/c0t6d0
To add a supported SCSI card online at 2/4.0.0:
scsictl -o ola_params 2/4.0.0 -1 -1 -1 -1
To issue a get_target_parms
command on a SCSI target with a tgtid of 2 using /dev/c8xx2 as the
ctrl device:
scsictl -t 2 -c get_target_parms /dev/c8xx2
To display limits and negotiable parameters of a device and then reset the SCSI target:
scsictl -c get_lun_parms -c reset_target /dev/rdsk/c0t6d0
WARNINGS
Not all devices support all mode parameters and commands listed above. Changing a mode parameter
may have no effect on such a device.
Issuing a command that is not supported by a device can cause an error message to be generated.
scsictl is not supported on sequential-access devices using the tape driver.
The
immediate_report mode applies to the entire device; the section number of the device argument
is ignored.
To aid recovery, immediate reporting is not used for writes of file system data structures that are main-
tained by the operating system, writes to a hard disk (but not a magneto-optical device) through the
character-device interface, or writes to regular files that the user has made synchronous with
O_SYNC or
O_DSYNC (see open(2) and fcntl (2)).
