Why doesn't megaraid storage manager restore the array?

Question

System administration

Good afternoon!
The situation is as follows, 2 disks (raid-1) are connected to the raid controller, and everything was ok, but yesterday, for some reason, the manager threw out messages that it was offline. After the reboot, he saw the controller again, but now he writes that one of the disks is unconfigured, and does not start the automatic recovery operation.
Tell me, what could be the reason?

Answer 1

Looks like one disk has failed. Are you reading data from another?
