InterpretationFault (3)Online (2)Activity (1)
The disk has failed and has been placed offline.
You can replace the disk.
OnOffOff
One of the following conditions applies:
• It is not configured as part of an array.
• It is part of an array, but it is a replacement drive that is not
being accessed or being rebuilt yet.
• It is configured as an online spare.
If the drive is connected to an array controller, you can replace the
drive online.
OffOffOff
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, will also cause this LED to light up.
• Event Monitoring Services (EMS) sends an alert message when physical or logical drive
failure occurs. For more information, see “Event Monitoring Service” (page 55), for details.
Use the sautil <device_file> command to confirm physical disk failures.
The LOGICAL DRIVE SUMMARY section ofthe sautil <device_file> command output
lists the status of all logical drives known to the RAID firmware.
The SCSI DEVICE SUMMARY section of the sautil <device_file> command output lists
all configured disks and all 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.
For example, in the following sautil <device_file> command output excerpt, spare disk
1:2 is being substituted for failed disk 1:1, which is why the logical drive is in the RECOVERING
state.
