•
An array expansion was aborted.
•
The logical drive is temporarily disabled because
another logical drive on the controller had a missing
disk at power on.
USING INTERIM RECOVERY MODE
Also known as a “degraded” state. A physical disk in a
fault tolerant logical drive has failed. For RAID 1, 1+0 or
5, data loss can result if a second disk fails. For RAID ADG,
data loss can result if two additional disks fail.
READY FOR RECOVERY OPERATION A replacement disk is present, but the rebuild has not started
yet; for example, because another logical drive might be
rebuilding. The logical drive also returns to this state if the
rebuild is aborted due to unrecoverable read errors from
another disk.
RECOVERING
Physical disks in this logical drive are being rebuilt.
WRONG PHYSICAL DISK WAS
REPLACED
When the logical drive was in a degraded state, the system
was powered off and a disk other than the failed disk was
replaced.
PHYSICAL DISK(S) NOT PROPERLY
CONNECTED
When the system was powered off, disks were removed.
Any other logical drives are held in a temporary
FAILED
state when this occurs.
EXPANDING
The data in the logical drive is being reorganized because:
•
Physical disks have been added to the array (capacity
expansion).
•
The stripe size is being changed (stripe size migration).
•
The RAID level is being changed (RAID level migration).
NOT YET AVAILABLE
A capacity expansion operation is in progress (or is queued
up) that will make room on the disks for this new logical
drive. Until room is made on the physical disks, the newly
configured logical drive cannot be read or written.
QUEUED FOR EXPANSION
The logical drive is waiting to undergo data reorganization
(see
EXPANDING
). Possible causes for the delay are a
rebuild or expansion operation that might be in progress.
Physical disk state definitions
The Status column of the SCSI Device Summary in the
sautil <device_file>
command output
example also provides useful troubleshooting information. To interpret the status of physical disks,
use the following physical disk state definitions. The physical disk state definitions are also included
in the
sautil
manpage.
OK
The physical disk is configured in one or more logical drives and is operational.
SPARE
The physical disk is configured as a spare disk.
UNASSIGNED
The physical disk has not been configured in any logical drives.
FAILED
The configured physical disk has failed.
NOTE:
The state of a SAS SES (storage enclosure processor) device is always FAILED. This is
because the enclosure is not a DISK device. It does not indicate that the enclosure has failed. To
confirm this, review the description for the physical device in the
sautil <device_file>
command output. The “Last Failure Reason” for the enclosure will be “NON DISK DEVICE.”
