> Fence_scsi is using unique keys to identify machines that have reservations. These keys are either manually selected (key / --key on commandline) or automatically derived from cluster name & node name. But in order to find out it automatically, we need to know which node name should be impacted by fence/unfence action. Adding one of these option should help.
Right, I’ve just had a look at this and couldn’t see how to either find out how I might specify the key or the node name in the pcs command that creates the stonith configuration and what documentation I could find on the matter suggested that if you didn’t specify them then, as you say, it should automatically generate the key. However, it does look like this is a known issue on RHEL 7.1 variants… https://access.redhat.com/solutions/1421063
