Dear managers:
I have an old Alphastation 900 running Tru 64 5.0. When the power
failed it caused the disk heads not to spin up unless you tapped on it
with a screw driver.
Anyways, I "got" an identical interal disk from HP (it had faster RPM cycles)
and plugged in as dsk1c.
I then followed the advice of Dr. Blinn on copying disks using the
following commands after shutdown down to single user mode.
disklabel -z rz1c
dd if=/dev/rdisk/dsk0c of=/dev/rdisk/dsk1c conv=noerror,sync (notice
that I took the default block size because it wouldn't work with bs=somevalue)
It finished 25 hours later with no errors. I'm using the advfs for
3 partitions including root and usr.
Ok: The HP field engineer removed the old drive and we removed the
jumper on drive 1.
When I boot up I get a bunch of /sbin/it getconf: not found
/sbin/it message: not found, etc.
INIT: Command is respawning too rapidly check for errors.
Now I have the system backed up via vdump on a remote system and can
disconnect a tape drive from another Alpha and plug it in here. I have
boot CD rom and I know I can go the the SHELL to try to do some Sys
administration.
The system still thinks the drive is dsk 1 and not dsk 0 when I do some
tests so I think that is one problem.
Any suggestions before I use my CDs and tapes?
Thanks!!
