Physical disk - related errorsThe physical disk failsIf the physical disk fails, check the following causes:• A physical disk is not visible in the BIOS Configuration Utility or is offline.• A physical disk is highlighted red at the BIOS Configuration Utility .A physical disk is not visible in the BIOS Configuration Utility or is offline1. Check that the cables are properly connected.2. Check that the physical disk is installed properly in the system’s backplane.3. Check the system’s backplane for damage.4. Reinstall the physical disk and ensure that it is seated correctly in the system’s backplane.5. Check if the Physical Disk might be a SAS drive.6. Perform a Rescan, to perform either of the following:a. Update the status of storage devices attached to the controller.b. Fix an error caused by deleting or initializing a virtual disk.A physical disk is highlighted red at the BIOS Configuration Utility 1. Replace the physical disk. Depending on the RAID level of the virtual disk, data might be lost.2. Perform a rescan to confirm that the new disk was discovered.A dedicated hot spare failsIf a dedicated hot spare fails, check the following causes:1. The controller cannot communicate with the hot spare.2. The dedicated spare is not visible in the BIOS Configuration Utility or is offline.The controller cannot communicate with the hot spare1. Check that the cable from the controller to the physical disk is connected properly.2. Ensure that the physical disk is still assigned as a global or dedicated hot spare.3. Check if the physical disk assigned as the hot spare has failed.The dedicated spare is not visible in the BIOS Configuration Utility or is offline1. Check if the physical disk has been removed or has failed.2. Check for a loose or bad cable.Failed or degraded virtual diskThe removal of one physical disk from a virtual disk causes:1. A Volume or RAID 0 virtual disk to change to Failed status.2. A RAID 1 and RAID 5 virtual disk to change to Degraded status.3. A RAID 10 virtual disk to change to Degraded status (when a physical disk is removed from one of the mirrored sets).Re-insert the removed physical disk and perform a Rescan of the virtual disk.45
