[Linux-cluster] PowerEdge R610 idrac express fencing

[Michael Mendoza]

I contacted DELL and was told it was normal because it was idrac6 Express
and it use a shared LOM for OS and idrac.

I've rebooted manually the servers and lost connectivity with idrac for 120
seconds aprox.

The weird thing is fence_ipmilan works from a centos 6.4 server.

We have some others Hp servers with iLo and when I restart the server I
lost connection with ilo while booting
