Unable to Rebuild A Fault Tolerant Virtual DiskIssue: Cannot rebuild a fault tolerant virtual disk. For more information, see the alert logfor virtual disks.CorrectiveAction:The replacement disk is too small or not compatible with the virtual disk. Replacethe failed disk with a compatible good physical disk with equal or greater capacity.Fatal Error Or Data Corruption ReportedIssue: Fatal error(s) or data corruption(s) are reported when accessing virtual disks.CorrectiveAction:Contact Dell Technical Support.Physical Disk Displayed As BlockedIssue: One or more physical disks is displayed as Blocked and cannot be configured.CorrectiveAction:Update the PERC cards to the latest firmware available on dell.com/support.Multiple Disks Become InaccessibleIssue: Rebuilding the physical disks after multiple disks become simultaneouslyinaccessible.CorrectiveAction:Multiple physical disk errors in a single array typically indicate a failure in cabling orconnection and could involve the loss of data. You can recover the virtual disk aftermultiple physical disks become simultaneously inaccessible. Perform the followingsteps 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 disks are present in the enclosure.3. Turn on the system and enter the BIOS Configuration Utility ( ) utility.4. Import the foreign configuration.5. Press at the prompt to import the configuration, or press to enter the BIOS ConfigurationUtility ( ) and either import or clear the foreign configuration.If the virtual disk is redundant and transitioned to Degraded state before going Offline, a rebuildoperation starts automatically after the configuration is imported. If the virtual disk has gone directly tothe Offline state due to a cable pull or power loss situation, the virtual disk is imported in its Optimal statewithout a rebuild occurring.NOTE: You can use the BIOS Configuration Utility ( ) or Dell OpenManage storagemanagement application to perform a manual rebuild of multiple physical disks.
