● 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: Corrective action: 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. 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. S160 controller lists M.2 drives Description: Corrective action: In RAID mode, M.2 drives mapped to onboard SATA controller are claimed by the S160 controller. This is an expected behavior and no action is required. Error in displaying the CD/DVD-ROM while in legacy mode Description: Corrective action: 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. Delete virtual disks so that the number of virtual disks does not exceed 10. Unavailable error under UEFI boot settings Description: Likely cause: In an NVMe configuration Embedded RAID controller 2 is unavailable under UEFI boot settings. 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. S160 does not display greater than ten virtual disks in the BIOS Configuration Utility or CTRL R Likely Cause: Corrective Action: The function is not supported. 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. Troubleshooting your system 41

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

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.

S160 controller lists M.2 drives

Description:

In RAID mode, M.2 drives mapped to onboard SATA controller are claimed by the S160 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.

S160 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.
