No , there is no way to do this. 
Always the request will be from the real  server name. That's why you must
put both virtual and real server name to the server list of all netbackup
clients (and media servers). As I write this is what the cluster aware
installation of netbackup doing. Don't forget the cluster_name in the
vm.conf.

Stefanos and others,

Quick followup question to your last tip.

This might be a dumb question, but does anyone know on Windows how to make
the "requests" coming from netbackup come from a virtual name. So if my
master servers real name is server1.domain.com and I create a virtual name
in DNS of nbmaster.domain.com (with a different ip address of course) how
can I make sure netbackup is going out using nbmaster.domain.com and not
server1.domain.com? Both IP's are bound to the same network card on the
server.

I've tried to figure this out by just adding in the virtual name to one of
my media managers. When looking in the logs all I see if the access denied
message for server server1.domain.com.

Thanks guys!


Kris

Well we have install linux master server to a lot of our customers. Both for
small and big installations. The bigest is an isp with more than 200 network
clients, 1master and 1 media server. We had problems with 4.5 but with 5.x
no problem at all.But this is more personal (and customer) decision.

For the migration, don't go through importing. Just copy the /netbackup/db
and /volmgr/database directories (exclude the ltidevs robotic_def and
globdb) Also DON'T copy the var folder (the license keys are bundle with the
server name so if you copy the var folder netbackup will not come up). Take
care for any link you may have inside the db folder (images
perhaps) and any disk storage unit you may have (for space reasons). 
Run the ./volmgr/bin/vmglob -set_gdbhost $newmastername And the device
configuration wizard only for the master server. Restart netbackup. Any
other media server you may have will register the drives himself after some
time. (but will be ready for backups immediately) Then run the command
bpmedia -newserve $newmastername -oldserver $oldmastername After that the
new master server is ready for use.

Tip. Install the new master server  with a virtual name and a different ip
than the server name and ip. This will help any migration in the future. If
you do this you must put the original server name to the netbackup server
list of all systems and to put the "cluster_name = $virtualname" to the
vm.conf file of the master server (This is equivalent to one node cluster
installation and helps to migrate muster server between systems eliminating
the  "name problem")

Greetings, all.

Currently, we are running 5.1 on an HP-UX L-class box, with a couple 'bots
(one old Surestore juke with (4) DLT4000s, one Neo juke with a DLT220). It
seems to work reasonably well. We have a few hundred tapes 'in circulation'.
So, we're probably one of the smaller sites that visit this list. :>)

We're taking the plunge, and planning a migration of our backup environment
to Red Hat Linux (the HP-UX maint fees will pretty much pay for the change).

My thought on migration was to hook the Neo juke up to the new RH box,
install Netbackup with the new servername, and import the SDLT tapes (around
thirty). When they have been satisfactorily imported into the new server's
database, backup the catalog on the old box, and then delete the media from
the HP-UX box.

Then, we'd run the boxes simultaneously for a while, and once we feel
confident with the new server, follow the same basic operation with the
'regular' dlt's and the other juke and decommission the HP-UX box.

It would appear that this isn't all that different than a disaster recovery
scenario, exc that I can't re-use the catalog as the server name is
different (and I've always hated the current name of the backup server
anyway). 

What other recommendations/caveats could you folks suggest? I'm sure that
I've missed a slew of things. :>)

Cheers,

-dd
