HP Smart Array 6400 Series Controllers Support Guide, September 2007

RECOVERING One or more 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, one or more 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:
1. Physical disks have been added to the array (capacity
expansion).
2. The stripe size is being changed (stripe size migration).
3. 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 may 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. Use the following physical
disk state definitions to interpret the status of physical disks. 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.
The sautil <device_file> scan Command
The sautil <device_file> scan command tells the Smart Array Controller to rescan all
SCSI buses. For example, when you hot-plug a physical disk into the system’s internal drive bay,
run a scan.
The sautil <device_file> accept_media_xchg <logical_drive_number> Command
The sautil <device_file> accept_media_xchg <logical_drive_number> command
instructs the Smart Array Controller to do the following:
1. Set the state of the specified failed logical drive to OK.
2. Set the states of all failed physical disks that have been hot-plug replaced to OK.
CAUTION: This option preserves the RAID configuration, logical drive configurations, and
controller settings. If more disks failed than the RAID level can accommodate, data on the failed
logical drive may be compromised. If data is compromised, you must restore from backup media.
In the following example, logical drive 0 accepts a media exchange.
# sautil /dev/ciss7 accept_media_xchg 0
