Ignite backup

musaddaq_2 — Wed, 28 Dec 2005 04:07:19 GMT

Hi Guys
We have Oracle 9i RAC on HP-UX (11i) on 2 database server with EVA disk array clustered with M/c service guard.
3 shared VG's are created initially and all datafiles are residing on these 3 vg's in its respective LV's.
I am taking the ignite backup every month.
Now my questioin is If something goes wrong and if i restore through ignite backup will it restore all the VG's and their restecive LV's
or it will just bring up My server.

Regards
Musaddaq

Hi Musaddaq,

I don't know what commando you are using for a ignite tape, but normally is it only vg00 which is on the ignite tape

So a restore will bring up only the server

Hi Musaddaq ,

What command are you using for Ignite backup.
Remember Ignite backup make_tape_recovery will take backup of your vg00 , and rest of the vg must be backed up using your backup software , like DP or NBU.

Cheers,
Raj.

Hi Guys
Thanks for the response.
I am not talking abt the data. I can restore the data. But what abt my VG's and LV's
will it come up or everything is gone for a toss.

You should store all your config files and once the ignite backup is completed, you can restore it. All datas in the disks will be preserved.

Hi Musaddaq,

All the current structure of vg00 and data will comeback, when you restore using the ignite backup tape.

Remember to use the flag , -x inc_entire=vg00 option. and -I for interactive.

Cheers,
Raj.

Musaddaq ,

Also remember to check the backup status of the Ignite backup tape . You can run it every sunday and write a script to send you the success/failure status by email.

check the log file using:
# cat /var/opt/ignite/recovery/latest/recovery.log
| grep -i successful

Cheers,
Raj.

The comand which i use is.

#/opt/ignite/bin
#make_tape_recovery -A -v -a /dev/rmt/1mn(tape path)

Hi Musaddaq,

You can include , -I (for interective restore) , & -x inc_entire=/dev/vg00 (for entire vg00 ).

So it will look like this:

# make_tape_recovery -A -I -v -x inc_entire=/dev/vg00 -a /dev/rmt/1mn

[ you can use -p for preview. ]

For details you can check # man make_tape_recovery

hth,
Raj.

Hi,

As all the files are backup up in vg00 if the physical layout of the system is not changed and only physical disk is replaced, the system should be able to activate the VGs by itself.

In some cases allthough we are required to vgimport the VG's. But this is what you will require at the max. to do for getting the datafiles accessible.

HTH,
Devender

Musaddaw,
I use this to ignite all my servers.

make_tape_recovery â a /dev/rmt/0mn -I -t "Make recovery of system `uname -n` on `date`" -v -x inc_entire=vg00

Re: Ignite backup

Darren Etheridge_2 — Thu, 29 Dec 2005 12:36:43 GMT

the above was supposed to read:

make_tape_recovery -a /dev/rmt/0mn -l
-t "Make recovery of system `uname -n` on `date`" -v -x inc_entire=vg00

When restoring it will give you the name of the system, the date ignite was run and as with almost all ignite backups, restore all of your file and disk structures.

Hope this helps :)

If you are asking if ignite will restore the existing volume group / logical volume configuration, the answer is yes:

"The make_tape_recovery tool captures enough information from the
system so that during a recovery it may reconstruct all visible
aspects of the prior LVM configuration. This includes logical volume
and volume group names, attributes, and even minor number values. The
tool also ensures that the new logical volumes reside on the same
disks within the volume group as they did before."

If you are asking if it will restore the data residing on volume groups (other than vg00) the answer is no.

also note that after igniting the server, disk mirroring (if used) will not be in effect for the recovered vg / lvols

Thanx Guys
For your response.
Finally i came to the conclusion is with ignite backup i can recover my /dev/vg00 only. and for rest of my VG's and LV's i have to look for some other backup solution.

Thanx once again
