On an IBM x3550 with two disks in hardware raid 1, have I heavy led activity on both drives, as soon as the raid controller is initialised at boot. It have been like this for more than a month, and the server doesn't do anything. It is a hit spare for a name server.
The raid controller doesn't report any issues.
Question
Have anyone an idea how I can debug this further and find the faulty disk or hardware?
