The package is tested
on VxVm 1.3 to 3.1, and is based entirely on standard vx-commands.
There is no guarantee it will work to regen diskgroups saved from one installation into another installation using an OLDER version of VxVM. (This due to dg-versions) The other way looks ok then..
here is an example on how to install:
#/usr/sbin/pkgadd -d /tmp/ESMvxbu.bin
The following packages are available:
1 ESMvxbu Regeneration utility for VXVM
(sparc) 2.0 ,REV=1.1
Select package(s) you wish to process (or 'all'
to process

Thats it. Now, it's even configured to run via cron every night
at 1 o'clock
#crontab -l | grep vx
0 1 * * * [ -x /usr/vx/Save_All_DG
] && /usr/vx/Save_All_DG /usr/vx
here's where it is installed:
#cd /usr/vx
#ls
1.make_DG 2.Restore_DG Save_All_DG Save_DG utils
#ls utils
1.save_info 3.make_new_DG count_configs remove_volume
2.remove_from_DG RUNME remove_disk
Here is how to use them:
Lets say we lost the diskgroup esmDG.....
#cd /usr/vx/RESTORE/esmDG
#../../1.make:DG esmDG
#../../2.Restore_DG esmDG
..and that's all. All you now have to do is mount he filesystems.
There is also a copy from the original vfstab-file here.
Now, let's say you want to move the volumes vol01, vol02 and vol03 from
esmDG to newDG
First, you have to be sure it is possible. That is, you have to move
subdisks involved in other volumes away from the
disks that belongs to vol01, vol02 and vol03, so that the disks as
well can be moved.
At last, you have to stop all processes running on the volumes, and
umount them. Then, you're ready!
CAVEAT: Make sure no names in the target DG is the same as in your moved volumes, this goes for sd, plex and volumes (and disks of course)
#cd /usr/vx/utils
#1.save_info esmDG vol01 vol02 vol03
#2.remove_from_DG esmDG vol01 vol02 vol03
(if this step fails, it tries to tell you why, fix it, and run step
2 again until it succedes)
#3.make_new_DG newDG
(newDG can either be an already existing diskgroup, or a non-existing
(then it wiull be created)
That's all, again, all you have to do is mount the filesystems. remember
they are in a new dg now, so you have to edit /etc/vfstab.
