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 52.
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.
RAID disk created from the NVMe PCIe SSDs not
appearing in operating system environment, showing as

Description
RAID disk created in UEFI mode from the NVMe PCIe SSDs are not discoverable in the operating system mode.
Corrective Action
Ensure that the partitioned drives are not deleted. Install the PERC S140 driver to see the RAID disks. See
Installing the drivers
on page 38 for more information.
Cannot perform an Online Capacity Expansion or
Reconfigure on a virtual disk
Determine whether these physical/virtual disks were migrated from a legacy controller with mixed RAID levels. If so, Online Capacity
Expansion/Reconfigure by adding physical disk on such a set of physical disks is not allowed.
Unable to configure RAID on NVMe PCIe SSD using a third
party RAID configuration utility
Corrective Action
Ensure that the NVMe is set on
Non RAID
mode. See
