Clear the preserved cache from 16-Port 12Gbps SAS-3 Internal RAID HBA using system BIOS Menu.

If there is any drive failure, there are chances that the controller might have some cache content which need to be written onto the failed disks, if the customer rebooted the server without clearing the cache, then the controller will go into safe mode and system will fail to boot if the boot disks are under the raid controller.

In this case, manually clear the preserved cache from RAID controller using the system BIOS Menu.
