[SunHELP] Sparc 20 sees new hard drive but won't boot from it

[Zakaria A. Mattar]

You can fix that by doing the following steps at the OK prompt:
OK setenv boot-device disk# (# specified by the jumper)
OK setenv diag-switch? false
OK boot disk #

Then everything will be ok if not reply this email with no it's not

Okay, Here's the situation:

I have a sparcstation 20 that I bought 2 new hard drives for. They're IBM
U160 drives (model dmvs, 9 gig). I added one of the new drives, boot -r'ed,
and partitioned the new drive. I then copied all of the data from the
original 4 gig drive to the new 9 gig drive, 1 partition at a time using the
following commands (taken from the ufsrestore man page)

mount /dev/dsk/c0t1d0s0 /mnt (mount the / partition of the new drive to
/mnt)

ufsdump 0f - /dev/rdsk/c0t3d0s0 | (cd /mnt; ufsrestore xf -)

After I copied all of the partitions I ran installboot to install the boot
block on /dev/rdsk/c0t1d0s0 (the new drive).

Thinking that everything was going my way, I halted the computer, removed
both drives, and put the new drive in as the root drive. When I turned it
back on, it didn't see the new drive and tried to boot from the network. No
matter what combination of jumper settings I've tried on the drive I can't
boot from it and open boot won't see it. However, as long as I boot from the
original hard drive with my new drive as a 2nd drive, the 2nd drive works
just fine.

Any ideas?
