Hi,
Lately, the disk on an AlphaStation 3000/300X has been having more
and more errors, until finally last week the machine in question
wouldn't boot. I called DEC (we have hardware maintenance) and a
technician arrived 20 minutes later with a replacement disk drive
(RZ26L). Here the fun started, as we had the bright idea of copying
the data from the old drive to the new one. Of course, when the
technician was there, the old drive behaved normally, and the machine
could boot off it, so we zeroed the disklabel on the new drive
(disklabel -z rz1, from memory), then used "dd" to copy everything
from the old drive to the new one. Here was the first hurdle - we
sat and waited for this to finish. And waited ... waited ... gave up
and went to lunch. In the end it took about 6 hours to copy the old
disk to the new, but we figured that after that it'd be easy - just
remove the old drive, set the new one to SCSI ID 0 as the old one was,
and boot. Unfortunately, first there was an error saying that
"usr_domain" was not a valid AdvFS filesystem, and then the machine
stopped part-way through booting.
We booted from the old drive again, and tried in various ways with the
disklabel command to make the new drive bootable, but kept striking
errors messages during booting.
Basically, all I need to know is how to copy the data from the old
drive and make the new one bootable and happy again.
Thanks,
David.
