Omniback 3.5 Cell Manager Migration

[Geetha Alagappan]

I need to migrate the Omniback 3.5 cell manager from one HP-UX 11.0 (32 bit)K570 box to another. I kind of have a sketchy idea - can somebody help me out with the detailed outline of how I go about doing this? Do I need a new licence file for the new cell server?

Also does Omniback 3.5 run on a 11.0 64 bit OS?

Thanks in advance.
Geetha.

Hi,
The omniback licence depend on the IP address of the cell server. If you change the IP address of your Cell Manager you have to upgrade your licence:

Hi again,
Do you have some clients?
Because if you change the hostname of the cell server you have to replace the name of the cell server on the following file:

/etc/opt/omni/cell/cell_server

/etc/opt/omni/cell/cell_info

Furthermore you have to adjust the owner of the catalogue database

Yes, I have several clients. Do I have to just change the
/etc/opt/omni/cell_server file and import the clients on the new cell manager?
Thx.
Geetha.

I'm running omniback 3.1 (yeah it's old), on a 64bit hpux11, hp9000, k570.
So does omniback 3.5 run on a 11.0 64bit OS? I still don't know. But 3.1 certainly works. Contact hp and ask them.

About the migration. I don't have a how-to list. But here are some tips.
-1. get license passwords for the omniback on the new box.
1. Try to lower the size of omniback's database. Run a purge.
2. stop omniback and backup with tar (or cpio, or pax, or fbackup) the following directories:
/etc/opt/omni <--where the config stuff is.
/opt/omni
/var/opt/omni <--where it's DB is.
3. start omniback again
Backup the omniback database to tape.
4. Stop omniback on the old box.
........onto the new box.............
5. install omniback on the new box. Use the DEMO license. WITH the new licenses you have, activate the omniback software.
6. Import the backup tape that you put omniback on.
7. Restore the omniback tape to a big BIG area. On the new box.
8. Stop omniback
Move the restored files to the correct spot:
that is.....
move /etc/opt/omni to /junk/etc/opt/omni
move /bigdisk/etc/opt/omni to /etc/opt/omni

move /opt/omni to /junk/opt/omni (I think)
move /bigdisk/opt/omni to /opt/omni (I think).

move /var/opt/omni to /junk/var/opt/omni
move /bigdisk/var/opt/omni to /var/opt/omni.
9. step to change the cell server name(??).
10. cross your fingers and start it up.
This process should be in omniback3.5 documentation. I would trust the book more than my memory. Hope it helps....steve

oh yeah big warning here: You really want to know how much disk space is taken by /var/opt/omni, /opt/omni, and /etc/opt/omni. You do not want to overload a disk! My short directions assume /junk and /bigdisk are HUGE filesystems.

thing 2: everybody's right. If you move the the hostname and ip address to the new box, it's easier.

Hi,
Yes, first of all you need a new license.

I am not exac sure about OmniBack 3.5 it is rather old today but it is no risk to do as follow.

Do a fresh install of OmniBack 3.5 on the new cell manager. Install the new license.
Back up the database on the old Cell Manager and restore it to a temporary location on the new server.

Shut down OmniBack on the new server.

Rename the current database directorys.
Move the restored directorys to the correct location.

Start up OmniBack.

Run the command "omnidbutil -change_cell_name"

Sure OB runs on 64bit HPUX11.00

All details about changing the host name and IP address of the cell server (which is identical to the move of 1 server to another) can be found in this thread I've started a while ago.

Didn't have any problems during the change.

hi,

iam running OmniBack 3.5 on HP9000/800 11.0, 64 bit, L-2000 and L-1000 machines in cluster without any problems.

1.Stop all the omniback processes on old server.
2. Install omniback on new server.
3. Copy existing /etc/opt/omni and /var/opt/omni to new cell manager
4. change the cell name.
omnidbutil -change_cell_name "old cell name"
5. apply licenses
