Hello Dary,

Dont know what VVR is.
But If you want to remove HA ( is it a pkg you want to remove or serviceguard itself)

to revert to non-serviceguard status

make them non-cluster-aware
for each volume group

vgchange -c n -S n vgname
cmhaltcl -v

for each vg
cmchange -a y vgname
mount each one of them (or use your /etc/fstab)

Can you give some more info, what do you want to do? (VVR- Veritas volume replicator? HA-Veritas cluster?)

Hello,

It has been a while since I used Veritas
Volume Replication last time.

Basically, the procedure to remove Veritas
Volume Replicator (VVR) components in a
Replicated Data Set (RDS) and leave the data
volume intact is:

a. Unmount the file system;
b. Stop the Replicated Volume Group (RVG);
c. Detach the rlink;
d. Dissasociate the data volume from the RVG;
e. Remove the RVG, rlink, and Storage
Replicator Log (SRL).

Something along the following path:

# umount /myvvr
# vxrvg -g mydg stop
# vxrlink -g mydg det <...>
# vxvol -g mydg dis <...>
# vxedit -g mydg -fr rm <...>
# fsck -F vxfs /dev/vx/rdsk/mydg/wlvol
# mount -F vxfs /dev/vx/dsk/mydg/wlvol /myvvr

I would suggest you check the documents at
Symantec (they acquired Veritas several
years ago)...

Cheers,
