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 command output. The "Last Failure Reason" for the enclosure will be "NON DISK DEVICE." The sautil scan command To instruct the Smart Array Controller to rescan all SCSI buses, use the sautil scan command. For example, when you hot-plug a physical disk into the system's internal drive bay, run a scan. The sautil accept_media_xchg command You can use the sautil accept_media_xchg command to instruct 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 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 might be compromised. If data is compromised, you must restore the data from backup media. In the following example, logical drive 0 accepts a media exchange. # sautil /dev/ciss5 accept_media_xchg 0 **** **** **** SAUTIL Support Utility **** **** **** **** for the HP SmartArray RAID Controller Family **** **** **** **** version A.02.11 **** **** **** **** (C) Copyright 2003-2006 Hewlett-Packard Development Company, L.P. **** ---- DRIVER INFORMATION Driver State READY ---- CONTROLLER INFORMATION Controller Product Number...........

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.”

The sautil <device_file> scan command

To instruct the Smart Array Controller to rescan all SCSI buses, use the

sautil

<device_file>

scan

command. 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

You can use the

sautil

<device_file>

accept_media_xchg

<logical_drive_number>

command to instruct the Smart Array Controller to do the following:

Set the state of the specified failed logical drive to

Set the states of failed physical disks that have been hot-plug-replaced to

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 might be compromised. If data is compromised, you must restore the data from

backup media.

In the following example, logical drive 0 accepts a media exchange.

sautil /dev/ciss5 accept_media_xchg 0
