Disk cloning
I had an external SCSI master disk that I used to clone to an identical external SCSI disk because the other SCSI disk would become corrupted. My original Master became corrupted so I used one of the other to good disk to copy back to the master. Unfortunately the new master needs to be able to boot but I don't know how to make the new master a bootable disk. I do not know anything about Unix commands and have been following a set of instructions that someone made 6 years ago.
I took a known good disk when I got to step 12 I reversed the 6 letter ID names and followed the rest of the instructions. I started the instructions over again and when I get to step 11 and try to log in as root is says that is a non bootable disk.
I am adding the instructions so someone with knowledge about UNIX might be able to make sense of this.
