The physical disk assigned as the global hot spare has failed When prompted at system startup, press Ctrl+R to access the BIOS Configuration Utility Ctrl+R. In the BIOS Configuration Utility Ctrl+R, select View Virtual Disk Details and press Enter. Determine whether the physical disk that is designated as the global hot spare has a status of Failed. 1. Check to see if the physical disk is malfunctioning or is physically disconnected. 2. Select another physical disk as the global hot spare. The physical disk assigned as the global hot spare is missing ● Check to see if the physical disk was removed from the backplane or cable connection, or whether the cables from the controller to the physical disk are disconnected or faulty. ● Perform a rescan to verify that the physical disk is still missing. A dedicated hot spare fails If 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 spare 1. 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. Determine if the physical disk assigned as the hot spare has failed. The dedicated spare is not visible in the BIOS Configuration Utility or is offline 1. Determine if the physical disk has been removed or has failed. 2. Check for a loose or bad cable. Failed or degraded virtual disk The 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. Cannot create a virtual disk on selected physical disks Determine whether these physical/virtual disks were migrated from a legacy controller with mixed RAID levels. If so, creating additional virtual disk on these physical disk is not allowed. 48 Troubleshooting your system
