On a Dell PERC 5/i system, if a RAID 1 or RAID 5 virtual disk fails, and if hotspare disks are available, the failed drive is rebuilt automatically without any user intervention. On a Dell PERC 6/i system, if a RAID 1, RAID 5, or RAID 6 virtual disk fails, and if hotspare disks are available, the failed drive is rebuilt automatically without any user intervention. On a RAID 6 virtual disk, if there are two failed drives, the failed drives are automatically rebuilt. NOTE: Dell SAS RAID Storage Manager uses the term rebuild to describe the operation that occurs when a disk is replaced in a RAID 1 array and data is copied from one disk to another. The BIOS utility uses the term synchronization to describe the same operation. Rebuild and synchronization in this context have the same meaning. This applies to the SAS 5/iR controller only. If a drive has failed, a red circle appears to the right of the disk drive icon: . A small yellow circle appears to the right of the icon of the virtual disk that uses this physical disk: . This indicates that the virtual disk is in a degraded state; the data is still safe, but data could be lost if another drive fails. Rebuilding a Drive on a Dell SAS 5/iR System or on a Dell SAS 6/iR System Follow these steps if you need to replace a failed physical drive on a Dell SAS 5/iR system or on a Dell SAS 6/iR system: 1 Note the number of the failed drive in the Dell SAS RAID Storage Manager window.

Maintaining and Managing Storage Configurations

On a Dell PERC 5/i system, if a RAID 1 or RAID 5 virtual disk fails, and if
hotspare disks are available, the failed drive is rebuilt automatically without
any user intervention.
On a Dell PERC 6/i system, if a RAID 1, RAID 5, or RAID 6 virtual disk fails,
and if hotspare disks are available, the failed drive is rebuilt automatically
without any user intervention. On a RAID 6 virtual disk, if there are two failed
drives, the failed drives are automatically rebuilt.
NOTE:
Dell SAS RAID Storage Manager uses the term
rebuild
to describe the
operation that occurs when a disk is replaced in a RAID 1 array and data is copied
from one disk to another. The BIOS utility uses the term
synchronization
to describe
the same operation.
Rebuild
and
synchronization
in this context have the same
meaning. This applies to the SAS 5/iR controller only.
If a drive has failed, a red circle appears to the right of the disk drive icon:
. A small yellow circle appears to the right of the icon of the virtual disk
that uses this physical disk:
. This indicates that the virtual disk is in a
degraded state; the data is still safe, but data could be lost if another drive fails.
Rebuilding a Drive on a Dell SAS 5/iR System or on a Dell SAS 6/iR System
Follow these steps if you need to replace a failed physical drive on a Dell
SAS 5/iR system or on a Dell SAS 6/iR system:
1
Note the number of the failed drive in the Dell SAS RAID Storage
Manager window. For example, the number --:--:<port #> identifies the
enclosure, the drive, and the port, respectively.
2
Shut down the system, disconnect the power cord, and open the computer
case.
CAUTION:
Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Authorized Service
Technicians: Before performing any procedure, see your Product Information
Guide for complete information about safety precautions, working inside the
computer, and protecting against electrostatic discharge.
3
Find the failed disk drive and remove it from the computer case.
You can identify the disk drive by reading the number on the drive cable.
This corresponds to the drive number displayed in the Dell SAS RAID
Storage Manager window. Also, the drive 0 cable is color coded. For the
integrated controller, the disk drive number is on the motherboard next to
the cable connector.
