Re: must /usr reside on vg00
I guess you can put /usr to another VG than vg00, for sure in Single User Mode. Concerning the multi-user mode, i know that the system is doing a vgchange from all VG before starting rc scripts, but it has to be tested according to me, to be sure than no troubles will happen
regards
PJA.

Solution/usr must not reside on vg00. You can mount it on any non-root volume group.
For example, when you use make_recovery -A, the recovery tape will include data from root volume group plus data from any non-root volume group containing /usr. You can find this in Ignite manual or man make_recovery.

Re: must /usr reside on vg00
/usr does not have to reside on /dev/vg00.
Only /stand, /etc, /dev, /sbin and / have to reside on /dev/vg00.
Be carefull when moving to another disk, many utilities like fbackup, cpio, tar reside on /usr!! tar has an equivalent on /sbin however.
good luck,
Thierry.

Re: must /usr reside on vg00
having "/usr" on another VG is all well, you just have
to remember, when you are in single-user mode, you
will have to "vgchange -a y /dev/vgXX" before you do
the "mount -a" to mount "/usr" (to use "vi"?).
HTH,

Re: must /usr reside on vg00
#cd /usr
pwd
#/usr
find . |cpio -pdu /usr1
with this command you can copy all the data with all the permisions and the all configuration included the subdirectories.
2 step shutdown the system in single user mode with the following step
shutdown --> to shutdown the system in single user mode
- # vgchange -a -y vg00
- modify the fstab and change the new path for /usr to vg01/usr
note:you can modify the fstab and made change before shutdown
