Okay, I'm rebuilding my boot disk after a disk failure last weekend. I
posted a message about this earlier and I will summarize responses to that
earlier message and this one once I get everything going.
Based on some advice I got from this list together with some material I
located in the documentation I put together a sequence of steps that I
believed would do the job for me. I'm using Tru64 v5.1A on a DS10. All
file systems are AdvFS; no LSM.
Everything went very smoothly (My tapes work. Yeah!). At the very end of
the process I attempted to reboot the system into single user mode to look
around a bit before bringing it on line fully. During the boot process I
was told that a valid boot block existed on the boot disk (it was also the
correct disk... the new one). However just after saying "jumping to
bootstrap code" I got
"Unable to open osf_boot"
and the process halts. I'm not sure what to do about this; so far I
haven't found anything helpful in the documentation. I'm hoping someone
here will know.
Some more information...
When I was setting up the new disk I used the command
disklabel -wr -t advfs /dev/rdisk/dsk0c
to write a "standard" disk label to the disk. I then read it back with
"disklabel -r /dev/rdisk/dsk0c". I didn't like what I saw (a couple of the
partitions were too small) so I did "disklabel -e /dev/rdisk/dsk0c" to
edit the label more to my liking. This seemed to be fine but now I'm
wondering if this might have caused some kind of problem for me.
I did create the root_domain file domain using the "-r" option of mkfdmn.
I created file sets fine and used vrestore to bring my files off the tape.
The file domains all looked good in so far as I could tell. Could there be
some problem with my root domain? Note also that the partition containing
my root domain is not the same one as it was originally. I did (manually)
patch up the links in /etc/fdmns after restoring from tape (the
documentation talks about this). However, perhaps I need to change
something else somewhere?
Thanks for any helpful advice you can offer.
Peter
