DR Test

vpons — Wed, 11 Apr 2007 12:59:32 GMT

I created ignite tape as
1. make_recovery -A
and the following on completion
2. mt -t /dev/rmt/omn
I placed on the standby server and booted the system with the sequential device.
When install was completed, I found vg01 structure with data but I expected only vg00.
Why did this happen?

The standby was a production image before I started.

Hi:

You don't specify what your vg00 looks like when you actually make your Ignite tape.

Look at the manpages for 'make_recovery' on your server. I think you will find the answer to your question there.

That said, 'make_recovery' was deprecated a long time ago and replaced with 'make_tape_recovery'. Fetch a current version of Ignite from here:

James,
We are still on 10.20 (the desupported version) and have been creating ignite tapes using make_recovery.

Hi,

If /usr is on vg01 and if you used the -A option then, vg00 as well vg01 will be included in the archive.

Court,

I checked the arch.include file and it has list of all vg01 filesystems too along with vg01

Sundar,
/usr is in vg00.

been awhile since i used make_recovery. but usually with the -A option it will include anything that is in that file by default. Also as Sundar mentioned, if /usr is located in vg01 then it wold get included also. you should check out the man for make_recovery and look at the -A option and also search for the word inclusion.

Shalom,

Even when you specify vg00 the LVM structure for the entire machine is preserved. This lets you restore a system and after boot, jump back on and mount all the storage that was connected.

In a DR situation, you'll have different storage and need to vgexport vg01 and start again.

make_recovery -A ???

Big time obsolete. make_tape_recovery is the current standared, and consider getting Ignite up to date now before an actual disaster.

I've done a disaster, it wasn't fun or pretty, but at least I know in advance I'd used the best tools.

-A (full volume group -vg00)

I had done a lot of ignite tapes on 10.20
by using the below command:
/opt/ignite/bin/make_recovery -ivCA

(if you use -C, you can use check_recovery to check up if the system has been changed and need to create a new tape) and -i for interactive bootup (if in case you need to alter the file system sizes while restoring)

As Sundar mentioned, it copies the other VG if the /usr is on the other VG.

There is another option to include all the VGs on the tape, if you use -A. I think it needs editing the arch.include
file or similar one. I totally forgot.

I do not have access to 10.20 right now.
