We have a server with three disks. Two of them are in RAID 1 defined in BIOS. One of these is showing an error at the bootup screen with the corresponding disk serial code in red.
I intend to replace it but I'm very wary of doing something wrong.
Is it just a matter of turning the server off, replacing the disk, and turning it on then waiting for the disks to synchronize?
We haven't bought the replacement disk yet. The defective one is a 1.8 TB (2 TB?) Hitachi hard disk. Is there a way to see the RPM (7200 or 5400) in order to buy the correct one without having to turn the server off? (I have no problem in turning it off, it would just be more convenient that way).
I'm assuming a missing disk won't affect the RAID 1 config settings (the server will only lose its mirror disk until a replacement is put in the slot) but out of curiosity I'd like to be sure. Will the RAID 1 settings be kept unchanged?
