Folks,
=20
Let me amend this.  I did this twice with NetBackup 3.4 on Solaris 8.
I guess I just live right.  :-)

Dennis,
=20
I've changed the hostname of the NetBackup master a couple times:
=20
1) Save the NetBackup catalogs, noting which tape is used.
2) Rename the master server.
3) Restore the catalogs with:
    bprecover -r -tpath /dev/rmt/0cbn -dhost [new_hostname]
4) Check that all media servers refer to the new master name as
the volume database host.  I believe /usr/openv/volmgr/bin/tpconfig
can be used to configure this.
=20
This is not a supported migration scenario, but it works.
=20
Good luck.

Thanks William and David!
You're right, Veritas Tech support told me that it is reallllyyyyyyyy =
very hard to change the hostname. He advised that I get a Veritas guy =
here and do the work ( which I think I will not do because it will cost =
money). I'll just stick to my current hostname and just make an alias =
for what I want it to be.

Regards,
Dennis

   =20

 =20

>From what I understand NBU integrates the hostname into itself is=20

such a way that it's very difficult to know where it is and what=20

kind of fall out can result from this change.



   =20

   That's true enough. Roughly speaking, you pretend to have a server =
failure and then "recover" onto the new server.
