Identifying physical disks
I am sure this is really simple.
I have a setup of 2 disks (sda, sdb) which are outwardly identical, and
are mirrors of each other. Together they form 3 raid1 devices. Both
disks can boot.
Now sda has bad sectors, and I should replace it. But which one of the
physical disks is sda??
The machine boots fine from either one of the disks, (and the booting
disk of course is always called sda).
