LLT lltconfig ERROR V-14-2-15238 node 0 already exists in cluster 4 and has the address - 10.9.5.33.
LLT lltconfig ERROR V-14-2-15241 LLT not configured, use -o to override this warning.

# cat /etc/llttab
set-node nodexyz
set-cluster 100
link link1 /dev/udp - udp 50000 - 10.20.30.1 -
link link2 /dev/udp - udp 50001 - 10.20.31.1 -

Workaround :
For nodes on different subnets, set the broadcast address in /etc/llttab depending on the subnet that the links are on.

#/sbin/gabconfig -U
#/sbin/lltconfig -U

# cat /etc/llttab
set-node Node0
set-cluster 1
link link1 /dev/udp - udp 50000 - 10.20.30.1 10.20.30.255
link link2 /dev/udp - udp 50001 - 10.20.31.1 10.20.31.255

Configure the driver for use.

#/sbin/gabconfig -c-n2

LLT will start without any issue.
