Valid arguments for are as follows: • auto • async • sync • ultra • ultra-2 • ultra-160 The sautil run_startup_script command To recreate the (/dev/cissX) device files, use the sautil run_startup_script command to run the Smart Array Controller startup script. Using sautil to check and update the controller firmware To confirm and update the firmware version installed on the Smart Array Controller, use the sautil command. HP recommends that you install the latest supported firmware version. NOTE: This section of the HP Smart Array Controller Support Guide focuses on the sautil command options used to confirm or change the Smart Array Controller firmware. Other sautil command options listed in the sautil help screen and detailed in the sautil manpages are described in "The sautil command" (page 66). To run the sautil command, you must log in as a superuser. Before running the sautil command to confirm or update the controller firmware, you must know the device file name for the Smart Array Controller. Determining the Smart Array series controller device file You can determine the device file for the Smart Array Controller from the output of the ioscan -kfnd ciss command. An example of the ioscan output listing the Smart Array Controller device files follows: # ioscan -kfnd ciss Class I H/W Path Driver S/W State H/W Type Description ext_bus 5 0/6/0/0/0/0/1/0/0/0 ciss CLAIMED INTERFACE PCIe SAS SmartArray P400 RAID Controller /dev/ciss5 In the example, /dev/ciss5 is the device file for Smart Array P400 Controller. Determining the Smart Array series controller firmware version You can determine the firmware version in the ROM on the Smart Array Controller by using either the sautil command (extensive output), or the sautil -s command (shortened output). An example of the sautil command output is provided in "The sautil command" (page 66). 84 Troubleshooting

The sautil <device_file> set_transfer_rate <rate> command
To set the Smart Array Controller SCSI transfer rate to a lower speed than the controller normally
allows, use the
sautil
<device_file>
set_transfer_rate
<rate>
command. Valid
arguments for
<rate>
are as follows:
•
auto
•
async
•
sync
•
ultra
•
ultra-2
•
ultra-160
The sautil <device_file> run_startup_script command
To recreate the (
/dev/cissX
) device files, use the
sautil
<device_file>
run_startup_script
command to run the Smart Array Controller startup script.
Using sautil to check and update the controller firmware
To confirm and update the firmware version installed on the Smart Array Controller, use the
sautil
command. HP recommends that you install the latest supported firmware version.
NOTE:
This section of the HP Smart Array Controller Support Guide focuses on the
sautil
command options used to confirm or change the Smart Array Controller firmware. Other
sautil
command options listed in the
sautil
help screen and detailed in the
sautil
manpages are
described in
“The sautil command” (page 66)
.
To run the
sautil
command, you must log in as a superuser.
Before running the
sautil
command to confirm or update the controller firmware, you must
know the device file name for the Smart Array Controller.
Determining the Smart Array series controller device file
You can determine the device file for the Smart Array Controller from the output of the
ioscan
-kfnd ciss
command. An example of the
ioscan
output listing the Smart Array Controller
device files follows:
#

/dev/ciss5
In the example,
/dev/ciss5
is the device file for Smart Array P400 Controller.
Determining the Smart Array series controller firmware version
You can determine the firmware version in the ROM on the Smart Array Controller by using
either the
sautil <device_file>
command (extensive output), or the
sautil
<device_file> -s
command (shortened output).
An example of the
sautil <device_file>
command output is provided in
“The sautil
command” (page 66)
