If you put the FORCE_RESTORE_MEDIA_SERVER in your bp.conf file of the devel
master server

FORCE_RESTORE_MEDIA_SERVER=fromhost tohost   <where fromhost is the original
host that backed up the data and the tohost is the server to be used for the
restore.

You should be able to complete the restores you are looking for, unless I'm
missing something obvious here.

I recently ran into a situation where I could not re-create an image
from importing recalled offsite tapes because one of the media had a
read error, very close to the end of the media.  There are 5 media used
in the image and it is highly likely that the data I want is not in the
bad sectors.

Now, if I understand correctly, I can't do a catalogue db recover from
the db tape that was also sent offsite without overwriting the existing
catalogue info (these images expired months ago).  So I went about
setting up a "development" master backup server with which to attempt
the following:

build a new master with a standalone DLT7k attached
recover the db tape
restore from the recovered image (hopefully)

I called Veritas support mid-way through this exercise and was told that
I could not recover in this way because of the name change of the master
server (I needed both boxes on the network), so I was officially screwed
(paraphrasing here...).  He suggested the following as an un-official
possibility:

create the db info from media on the production master (successful)
recover the catalogue tape onto the development server (successful)
copy the *.f file for the appropriate backup id from dev to prod
(successful)
restore data (not successful)

I got db errors (220 I think) and it never worked.  I have heard of
people doing alt master server recoveries on this list and want to know
how it works.  The easy answer would be to not have the alt on the
network and just make the nodename identical, then after recovery change
the name and put it on the network.  Would this be correct?  That way I
could copy over the entire image directory to the prod master and
probably recover.

Looking for advice.  Thanks.
