HP A7143A RAID160 SA Controller Support Guide

Troubleshooting
The sautil Command
Chapter 6 117
— 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
