General Information About Hard Drive Failure
Appendix C144
The sautil <device_file> command, can be used to investigate
undetected disks.
The SCSI DEVICE SUMMARY section of the sautil <device_file>
command output lists all of the disks the firmware has detected.
The Participating Physical Disk(s) section of the LOGICAL DRIVE
information contained in the sautil <device_file> command output
lists the channel and SCSI ID of all of the physical disks that have been
assigned to a logical drive.
By comparing the Participating Physical Disk(s) to the SCSI
DEVICE SUMMARY, you can determine if disks are missing or failed.
For example, in the following sautil <device_file> command output
excerpt, the physical disk on channel 1 with a SCSI ID of 1 does not show
up in the SCSI Device Summary, however, it is listed as a participating
physical disk in Logical Drive 0.
