for more information on privileged users.
- See sautil(1M) for tool details.
This section of the RAID160 Support Guide focuses on sautil command options that are used for online
troubleshooting of the RAID160 SA controller.
The sautil command option that is used for updating RAID160 SA controller firmware
(<device_file> download_hba_fw <fw_image>) is detailed in “RAID160 SA Controller Firmware” on
page 49.
The sautil command option that is used for updating physical disk firmware
(<device_file> download_dev_fw <fw_image> <ch>:<id> ) is detailed in “Physical Disk Firmware” on
page 58.
The sautil <device_file> reset_adapter option resets the adapter. Some situations that may require an
adapter reset include:
— Online replacement of the RAID160 SA is performed, but the logical drives on the replacement controller
are not detected
— A disk enclosure with an existing RAID configuration was hot - added and the logical drives on that
enclosure are not detected
The sautil <device_file> start_recovery option causes the RAID160 SA controller to start rebuilding
any logical drives that are in READY FOR RECOVERY OPERATION state. All logical drives in this state
will eventually transition to RECOVERING. Heavy I/O to the controller may delay this transition. There is no
adverse impact, if this option is invoked when no logical drives are in READY FOR RECOVERY
OPERATION state.
The following sautil troubleshooting command options, which are included in the sautil help screen and
detailed in the sautil manpages, are intended for HP support personnel. Detailed knowledge of the RAID160
SA driver and firmware is required to interpret the output:
<device_file> stat
<device_file> clear_stat
<device_file> get_trace_buf
<device_file> get_fw_err_log
The sautil command options that will be useful for HP customers troubleshooting a RAID160 SA controller
are:
sautil <device_file>
sautil <device_file> accept_media_xchg <logical_drive_number>
run_startup_script
