Issue:

Rebuilding the physical disks after multiple disks become simultaneously inaccessible.

Corrective Action:

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:

1. Turn off the system, check cable connections, and reseat physical disks.
2. Ensure that all the disks are present in the enclosure.
3. Turn on the system and enter the BIOS Configuration Utility (<Ctrl> <R>) utility.
4. Import the foreign configuration.
5. Press <F> at the prompt to import the configuration, or press <C> to enter the BIOS Configuration Utility (<Ctrl> <R>) 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.
