Hi,
I have a 2 node cluster ( 2 HP blade servers) sharing a FC volume where we keep the VMs
I am using fencing_ilo
After successful fencing, the node stays offline
When trying to start cman manually, the following error occur
" ... Unfencing self... fence_node: cannot connect to cman"
How/what is the procedure form bringing the fenced node back online ?
Here are some details:
