Physical Disk Failures and Rebuilds
Table 7-5 describes issues related to physical disk failures and rebuilds.
Table 7-5. Physical Disk Failure and Rebuild Issues
Issue Suggested Solution
Rebuilding the physical
disks after multiple disks
become simultaneously
inaccessible. Multiple physical disk errors in a single array typically
indicate a failure in cabling or connection and could
involve the loss of data. You can recover the virtual disk
after multiple physical disks become simultaneously
inaccessible. Perform the following steps to recover the
virtual disk.
CAUTION:
Follow the safety precautions to prevent
electrostatic discharge.
1
Turn off the system, check cable connections, and reseat
physical disks.
2
Ensure that all the drives are present in the enclosure.
3
Turn on the system and enter the CTRL+R utility and
import the foreign configuration. P
ress <F> at the
prompt to import the configuration, or press <C> to
enter the BIOS configuration utility and either import
or clear the foreign configuration.
If the virtual disk is redundant and transitioned to
Degraded state before going Offline , a rebuild operation
starts automatically after the configuration is imported. If
the virtual disk has gone directly to the
Offline state due
to a cable pull or power loss situation, the virtual disk is
imported in its
Optimal state without a rebuild occurring.
You can use the BIOS Configuration Utility or Dell
OpenManage storage management application to perform a
manual rebuild of multiple physical disks.
For information on rebuilding a single physical disk, see
"Performing a Manual Rebuild of an Individual Physical
Disk" on page 108.
