[Linux-cluster] PowerEdge R610 idrac express fencing



Good afternoon.

We are trying to configure 2 dell R610 with idrac6 EXPRESS in cluster with redhat 5.10 x64.

For testing we are using the command fence_ipmilan. We can ping idrac on the remote host. 

fence_ipmilan -a X.X.X.X -l usern -p xxxx  -t 200  -o status  -v   <-- works


fence_ipmilan -a X.X.X.X -l usern -p xxxx  -t 200  -o reboot -v

The problem is the server reboot, but while it reboot the idrac6 reboot too. so the host A after 120 seconds aprox lost connection and get the follow message.


Spawning: '/usr/bin/ipmitool -I lan -H 'X.X.X.X' -U 'usern' -P '[set]' -v -v -v chassis power on'...
Spawned: '/usr/bin/ipmitool -I lan -H 'X.X.X.X' -U 'usern' -P '[set]' -v -v -v chassis power on' - PID 10104
Looking for:
'Password:', val = 1
'Unable to establish LAN', val = 11
'IPMI mutex', val = 14
'Unsupported cipher suite ID', val = 2048
'read_rakp2_message: no support for', val = 2048
'Up/On', val = 0
ExpectToken returned 11
Reaping pid 10104
Failed

cman version is CMAN-2.0.115.118.e15_10.3


however I have other host with centos 6.4 and CMAN3.0... and the connection is not lost. I run the same command, the server reboot as well as idrac, the ping is back and the ipmi connection is not lost..

am I doing something wrong? I used the -t and -T option even 300 / 400 and it doesnt matter, the connection is shut after 120secounds. in centos work fine. ( I already opened a case with redhat and am waiting answer.)
Thanks
