- Getting help
● Whether the virtual disk is in Degraded status because one of the physical disks of a RAID 1 or RAID 5 virtual disk has failed,
or one of the physical disks of a RAID 10 virtual disk has failed. Press Ctrl+R and verify if the physical disks are offline or
missing. Remove and replace a failed physical disk. A second physical disk failure could cause a Degraded virtual disk to
change to Failed status.
● Whether the virtual disk is in a Failed status because one or more of the physical disks have failed. Press Ctrl+R and verify if
the physical disks are offline or missing. Remove and replace the failed physical disk or disks.
Other errors appearing on the BIOS screen
BSOD is observed while booting on the NVMe configuration server
Description: NVMe drives utilize the system resources, if more number of NVMe drives is connected to a server
having less number of cores, then there is a lack of resources to service the NVMe and BSOD can occur.
Corrective
action:
Ensure logical processor is enabled under BIOS HII > Processor Settings or remove some of the
NVMe drives before booting and hot insert the drives after booting.
S150 controller lists M.2 drives
Description: In RAID mode, M.2 drives mapped to onboard SATA controller are claimed by the S150 controller.
Corrective
action:
This is an expected behavior and no action is required.
Error in displaying the CD/DVD-ROM while in legacy mode
Description:
The maximum number of virtual disks supported in legacy BIOS mode is 10. The user will not be able to
view CD/DVD-ROM in the BIOS One Shot Boot Menu if the number of virtual disks exceeds 10.
Corrective
action:
Delete virtual disks so that the number of virtual disks does not exceed 10.
Unavailable error under UEFI boot settings
Description:
In an NVMe configuration Embedded RAID controller 2 is unavailable under UEFI boot settings.
Likely cause: This is an expected behaviour in an NVMe configuration only and not in a SATA configuration. This error
can be ignored as there is no functionality loss.
S150 does not display greater than ten virtual disks in the BIOS
Configuration Utility or CTRL R
Likely Cause:
The function is not supported.
Corrective
Action:
Remove all physical disks except for the last one(s) added. Then proceed with deleting the virtual disks
that are not needed. Remember to take account of the virtual disks that are currently being used.
Unable to delete virtual disks when there are more than 30 virtual
disks present in the system
Likely cause:
The function is not supported.
