Hi,

I have a 2 node cluster (xen1 and xen2) running on dl380 G3’s. There are 2 virtual machines running on these. From first node from the shell command line I can fence the 2^nd  node through the hp lights out port using /sbin/fence_ilo –a 192.168.1.53 –l aking –p password –v. I can also do the same from the second node and successfully fence the first node. When I fence the node that has control of one or more virtual machines they are migrated to the other node.

I had some issues with the default fence_ilo, found a nice fence_fast_ilo fencing script in an rpm: comoonics-bootimage-fenceclient. This seems to work much better.

 

If I fence a node in Luci this works too.

However, if I have a node running one or more virtual machines and run /sbin/reboot –f on that node, in /var/log/messages in the other node I get messages such as

xen1 fenced[3126]: agent "fence_ilo" reports: Unable to connect/login to fencing device

xen1 fenced[3126]: fence "192.168.50.116" failed

assuming that 192.168.1.53 is the 2nd server's ilo address and 192.168.50.116 is the 1st servers ilo address?

Can anyone advise why this is happening?

Cheers

Adam
