Re: [Linux-cluster] PowerEdge R610 idrac express fencing



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

This seems wrong, when doing a system reboot through IPMI, your BMC should not
reboot. does this happen if you use ipmitool or similar tool to reboot the
machine?
