Well, it DOES help if you're actually using the recovered EMM DB, come to think
of it.
I was migrating from a server with the files relocated from under to
/usr/openv/db to /usr/openv/netbackup/db/sybase to a server where, instead, I
opted to locate all DB files under /usr/openv/db, a separate partition, so
/usr/openv/netbackup/db is a sym link to /usr/openv/db/nb-db. Catalog recovery
does not, apparently, perform an online recovery of EMM: rather, it restores
the files from under /usr/openv/db. That meant that I needed to manually move
the DB files (importantly: not the binaries, since I'm switch processor
architecture and OS) from the old data directory (in my case,
/usr/openv/netbackup/db/sybase/data) to the new data directory (in my case, the
normal /usr/openv/db/data).
I'm sure there will be some other details I need to change in this process, but
at least nbemm starts now.
I'd still be interested to hear any tips from those who've tried this in the
past, of course.
One very important one that I'll share right now: so far as nbemm is concerned:
I run it on a service name, not the base OS name. That service name is
currently in /etc/hosts on the new backup server referencing an IP address
alias on the new server. This wouldn't work without that (as services would
start on the new server and then try to talk to nbemm on my old master, which
is still up and running).

Subject: Migrating a 6.5+ master server from one host to another
I'm in the process of moving from one NetBackup master/media server running
HP-UX 11iv2 to its replacement running RHEL 5.3, which I'd hoped would be
comparatively easy by way of nbrecover -wizard.
What I'm finding, however, is that nbemm *really* doesn't like getting moved to
a different hostname. I'm still hopeful that I can work through the kinks in
order to simply perform a catalog recovery on the new host, but it's clearly
not so easy as using this mechanism for DR recovery (in which I intend the
hostnames to match).
Has anyone attempted this in the past? Do you have a checklist of nbemmcmd
settings to change after bprecover but before restarting NetBackup (or is that
even feasible)?
