To upgrade the first half of the cluster
1
Stop all the applications on the nodes that are not under VCS control. Use
native application commands to stop the applications.

Switch the failover groups from the first half of the cluster to one of the nodes
in the second half of the cluster.
# hagrp -switch failover_group -to system03
3
Stop all VCS service groups.
# hagrp -offline group_name -sys system01
# hagrp -offline group_name -sys system02
4
Freeze the nodes in the first half of the cluster
# haconf makerw
# hasys -freeze -persistent system01
# hasys -freeze -persistent system02
# haconf -dump -makero
5
Stop VCS on the first half of the cluster:
# hastop -local -force

If you created local VxFS mount points on VxVM volumes, added them to the
/etc/fstab file, and comment out the mount point entries in the /etc/fstab
file.
7
Set the LLT_START attribute to 0 in the /etc/rc.config.d/lltconf file:
LLT_START=0

On each node of the first half of the cluster, edit the /etc/vxfenmode file to
configure I/O fencing in disabled mode.
# cat /etc/vxfenmode
