Other ways to identify a failed physical disk
Other ways to recognize that a physical disk has failed are as follows:
• The amber LED lights up on the front of supported StorageWorks disk enclosures if failed
drives are inside.
NOTE: Other problems such as fan failure, redundant power supply failure, or
over-temperature conditions also cause this LED to light.
• EMS sends an alert message when physical or logical drive failure occurs. For more information,
see “Event Monitoring Service” (page 59).
Confirming physical disks failures using sautil
To confirm physical disk failures, use the sautil <device_file> command.
The LOGICAL DRIVE SUMMARY section of the sautil <device_file> command output lists
the status of logical drives known to the RAID firmware.
The SCSI DEVICE SUMMARY section of the sautil <device_file> command output lists
configured disks and unassigned disks known to the RAID firmware.
The LOGICAL DRIVE sections of the sautil <device_file> command output provide
additional information on each logical drive.
