Mark,

You can do a savevg with no data.  We do this weekly to a directory on the
rootvg just before we create our bootable rootvg backup.

the script is

#!/usr/bin/ksh

# script to run a savevg with no data of every available volume group
# except root
# this is done weekly so that VGs can be easily recreated in the event
# of misadventure

logger "$0 started"
for vg in $(lsvg | grep -v rootvg )
do
        if lsvg $vg 2>&1 > /dev/null
        then
                echo "/*/" > /etc/exclude.$vg
                if savevg -eimXf /var/local/savevg/$vg $vg 2>&1
                then
                        :  # hey it worked
                else
                        msg="$0 no data savevg of $vg failed rc=$?"
                        echo "$msg"
                        logger "$msg"
                fi
                rm /etc/exclude.$vg
        fi
done

logger "$0 completed"

Certvg and demovg contain a lot of raw lvs.

Fellow ADSM'ers
I'm in the process of designing a disaster recovery plan for AIX.  We use ADSM
to backup our files, and I'm looking for a solution on rebuilding our non-root
volume groups.  I want just the volume group, logical volume, and filesystem
information without the data.  I could probably script it (in time), or I
thought someone
out there probably already has a solution.

Thanks

Mark
