By default ignite will take vg00. If you both disks are in vg00, no problem, if not you can include it as follows.

(Assuming that disk is in vg01)

Use -x inc_entire=vg01.

Check man page and x options.

The Ignite process consider data as in VGs and not in disks. Normally the image meant for vg00 (root) only. But if you want other VGs to be included, you can do that too provided the VGs are small enough to hold in your ignite tape. The command will be:

# make_tape_recovery -a /dev/rmt/device_filename -I -v -x inc_entire=vg00

# man make_tape_recovey for more details.

Is there any limitations in including disks in vg00.
Thanks

Yes. The maximum number of disks (PV) in a VG can be defined using -p option when you create the VG with 'vgcreate' command.

# man vgcreate

The default is 16 and the maximum is 256.

Again, your current setting can be viewed from:

# vgdisplay -v /dev/vg00

The Max PV parameter is the limitation for you now.

there may be a "terminology" issue here,

A "golden image" is more of a
complete system image that is created with the command

make_sys_image

The make_tape_recovery, is used more for "disaster recovery" command, to restore the system that the tape was created on.

make_sys_image will definately do more than one disk.

make_recovery has, or had some
flaws with two disks, even if
both were in the same volume group, being vg00.

I'll elaborate if requested, otherwise, I've typed enough :-)

I do it slightly differently but it includes all volume groups.

/usr/contrib/bin/make_sys_image -s local -d /images -u &

My make_sys_image script is a customization of the one that came with Ignite. I needed to include a few extra things.

This is a tested and production methodology.

-s local means stoer it locally.
-d /images means thats where I want the image file to go.
