LSI MegaRAID Bios – Loop where I have to delete Virtual Drive because of Preserved Cache

bioslsimegaraid

My server crashed tonight. I suspect the disks being full. I have four SSDs of the same kind connected to a LSI MegaRaid 4-port controller. The disk in slot 1 seems to be troublesome. I guess I could get it replaced.

The problem I am running into now when I choose Manage Preserved Cache – the cache being the problem in the first place – my only option is to delete the Virtual Drive.

Discard Preserved Cache

Deleting the Virtual Drive really is not an option. This would delete all my data, right? I am having trouble finding understandable documentation on this.

Delete offline drive

(How) Can I import the Virtual Drive as stated in the below message?

Message on Preserved Cache

Is there any chance from this point to see why the disk in Slot 2 failed?

Any hints/help is very much appreciated!

Thank you.

It seems that you lost access to two disks, the ones in Slot1 and Slot2. If true, this means that your RAID5 array is inoperable - and the controller is asking you to delete it
