lltconfig ERROR V-14-2-15121 LLT unconfigure aborted,

Hello,

I've a 2 node cluster, with on CP server and 2 fencing disks. But think something is wrong on my fencing configuration.

OS : RHEL6.6 

VCS 6.2.1

# gabconfig -a
GAB Port Memberships
===============================================================
Port a gen   816e15 membership 01
Port a gen   816e15   jeopardy ;1
Port b gen   816e1b membership 01
Port b gen   816e1b   jeopardy ;1
Port h gen   816e1e membership 01
Port h gen   816e1e   jeopardy ;1

# lltconfig -a list
Link 0 (bond0):
  Node   0 Node01 :   00:XX:XX:XX:XX:YY
  Node   1 Node02 :   00:XX:XX:XX:XX:YX  permanent

# cat /etc/llttab
set-node Node02 
set-cluster 229
link bond0 bond0 - ether - -
link eth2 eth-00:11:AA:77:BB:22 - ether - -

I don't have a eth2 on my server, I tried to remove the second line of my /etc/llttab and stop and restart 

#  /etc/init.d/llt  stop
