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

/etc/fstab file, and comment out the mount point entries in the /etc/fstab

file.

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

vxfen_mode=disabled

If the cluster-wide attribute UseFence is set to SCSI3, then reset the value to

NONE in the /etc/VRTSvcs/conf/config/main.cf file.

Stop all the modules on the first half of the cluster.

# /sbin/init.d/odm stop

# /sbin/init.d/vxfen stop

# /sbin/gabconfig -U

# kcmodule vxfen=unused

# kcmodule odm=unused

# kcmodule gab=unused

# lltconfig -U

# kcmodule llt=unused

On each node of the first half of the cluster, remove the following device files:

# rm -f /dev/llt

# rm -f /dev/gab*

# rm -f /dev/vxfen
