The physical disk is already part of a virtual disk
A hot spare cannot be selected if it is already part of an existing virtual disk.
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 on page 54.
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.
