I want to move /home and /opt out of the root volume group (vg00) to vg01 or vg02.

What would be the best course of action?

Any comments would be higly appreciated!

Create new logical volumes
mount it at /newhome

cd /home
find . | cpio -pudmvl /newhome
umount /newhome
umount /home
vi /etc/fstab
mount -a

Hi,

I dont think moving var to another disk should be a health talk as this is where all the system logs and tmp is available, in case the vg/disk containing var doesnot come up it would be more complex.

Any way if have to do this i'll do this way

lvcreate -n newhome /dev/vg01
newfs -F vxfs/hfs /dev/vg01/rnewhome
mount /dev/vg01/newhome /newhome

lvcreate -n newvar /dev/vg01
newfs -F vxfs/hfs /dev/vg01/rnewvar
mount /dev/vg01/newvar /newvar

cd /home
find . -depth | cpio -pvd /newhome
cd /var
find . -depth | cpio -pvd /newvar

reboot the system in maitance mode
break autoboot process
interact with IPL

ISL>hpux -lm

#cp /etc/fstab /etc/fstab.old
#vi /etc/fstab
change the entries corresponding to /var /home

boot normally.

Goodluck

venu

The procedures above will work, but please choose your cpio flags carefully. I personally use "cpio -pdumx" out of long habit.

u is unnecessary in the case of a fresh filesystem, but does not harm anything.

x is required if you are copying device files -- again not required in this case but not harmful and I prefer to use the same procedure no matter which directories I am working with.

p,d are absolutely required.

m should be used unless you wish to have the access times on all files changed.

I'm not sure how we went from moving /opt and /home to moving /var, but I wanted to put my two cents in.

Moving /var out of vg00 is NOT supported or recommended by Hewlett-Packard. The software and patch installer files are there, and SD-UX (swinstall) gets very touchy about where things are.
