SCSI Mirror issue
Posted on 2004-04-20
Have a server that has 2 36gig scsi hard drives. Mirror. They have the OS on them.
Have the same server with 3 72gig scsi hard drives. they are raid-5. Working fine. data bank.
one of the 36 gig drives failed and it broke the mirror. I went into the SCSI utility and checked the data. One of the hard drives has bad blocks. after rebooting form this, I got a blue screen (can't access boot device)
I unplugged the drive 0 from the scsi cable and by default, the other 36 gig drive moved to Drive 0. The system then booted using the one drive.
So I am in good shape..
Now I want to replace that hard drive. is it just as simple as adding the new drive in the place of the old one or should I move the drive that works up the cable to the drive that I took out and put the brand new drive in the place of drive 1. Then re mirror the drives?
Just looking for best pratice with no data loss.
