1. Cut a fresh ignite Tape. (This will take care of your VG00 and other system and OS related backups)
2. Take backup your other VG and Data backup with your omniback
3. Take LUN backup of your VA7400. This will save vital information about your VA and LUNs. VA might loose all the data once you power off the unit for a longer period!Involve HP ( if you have supprot contract) and let them know about this move.

Also have printout of your vg,sLV's,(vgdisplay -v ,lvdisplay -v ) bdf, kernel parameters (kmtune -l) and run print_manifest from /opt/ignite/bin.

Goodluck.

George --

Also, keep in mind the order that you want to power up the equipment after the system move.

The system needs to be powered up AFTER the disk drives are powered up and available.

If the system gets powered up first even if you interrupt the boot up sequence, the system may not "see" the disks on boot up which will cause some VGS not to activate.

Best regards,

Kent Ostby

George, ignite is not meant for LUN backups mainly for Vg00 and related VGs. Even DDS3 tapes only work upto 8GB compressed, if I remember correctly.

Omniback is very good for backing up data. I havent used Omniback in a while, but If I remember correctly, you can take a FULL backup to tape or keep your last full and do an incremental. If you have DBs on there, I would suggest your DBAs do a cold backup as well, so you have 2 copies of the data.

Omniback has a GUI that is very helpful. and HP has an online site for it as well.

------------------------------------------------
export DISPLAY=xx.xx.xx.xx:0.0 (change this to your IP address)

# /opt/omni/bin/xomni &
-----------------------------------------------

Here's a link to the docs pages..just pick omniback II and you can see all the manuals...

=-------------------------------------------------

I am assuming you are not merely moving the Servers but the Storage as well.

I would also do 2 ignite tapes for your servers...for redundancy.

LUN Backup can be initiated from Commandview
and iginte can be done by make_tape_recovery command.

/opt/ignite/bin/make_tape_recovery -a /dev/rmt/0mn -I -m tar -v -x inc_entire=vg00

Use Ignite for vg00 and do an OB2 host backup which will get everything including vg00 again. Next I would shutdown OB2 using omnisv.sh stop and then do a conventional backup using fbackup of /opt/omni, /var/opt/omni, and /etc/opt/omni. That will give you a full backup of OB2 in case it gets trashed. Shutdown your array in an orderly manner and that will write the array info to the drives.

Now, because the drives are the most likely victims of harsh treatment, I would remove each and every one of them; label them as to the original location and carefully pack them separately. I've moved quite a few boxes, some over long distances, and I've never needed a backup. Of course, in my case, anything that wasn't RAID'ed was certainly mirrored. If you are mirrored, backed up, and careful you won't never ever need them stinkin' backups but if you ain't .... --- it's one of God's little jokes.

I would also check all the connections and check that memory and boards are still tightly seated after the move.

Hi,

Make_tape_recovery -Ai
Ignite tape is enoug for your vg00 (root vol.group )
You can use fbackup command to make full backup of your system.
fbackup -f /dev/rmt/0m -v -i ( ofline backup), but if you use omnibackup that is good too.

If you have any database on your system you should stop them before you make any full backup of your system.

Succes
