Perhaps I should enable it? I don't know what that would do since the OS is already configured and data is on the boot disk. Now I need to know which drive is which, format it and make it available.Īlthough, I was thinking of just extending the volume to both disks act as one (logical) in some sort of raid set up? In Bios, raid is not enabled like it is on the other node. The OS boots and I have the "new" old drive physically installed. That will not change so it is a way to tell which drive name is used by which disk.
Using the command hdparm -I /dev/sda will spit out a lot of information and among that you will find the serial number of the drive in question.
Or you could remove the old disk and reverse which slot they're in (bear in mind that every time you physically unplug and replug and move a drive, you stand a chance of breaking it as they are fragile devices). If the wrong drive is set to boot first then you can probably change which one boots from within your BIOS setup.
When you insert the new one, the old one may (and sounds like it did) change drive name so what was /dev/sda might become /dev/sdb. Your first step is to make absolutely sure you know which disk is which.
