UCS C240 M3S Restart Issue - Preserved Discard Cache

Adam Hinchliff

Level 1

We have a CUCM cluster running on UC UCS C240 M3

After a restart of the host, we now have the following error appearing in the megaraid BIOS util.

Controller lost access to one or more drives, it's suggesting I discard the preserved cache.

Refer attached picture.

Question: Is this safe to do? No TAC support sadly.

Do you plan on restoring that virtual drive?

Stupidly i selected discard without saving it and it deleted the virtual drive meaning now I've lost the cluster.
