I've added in a 4th host to my Xen 6.2 cluster and I'm unable to get it to successfully attach to my existing storage repositories. I'm using 3 older IBM hosts and the 4th new one which is CPU masked so that it successfully joins the pool. I have two fibre switches, Cisco, which have the paths setup correctly for all four hosts to see the IBM san.
Currently I have 3 LUNs available in Xen Centre which are showing as connected to all hosts with the exception of the newest server which is shown as 'unplugged'. When I try and perform a 'repair' via the GUI it fails after PBD plug with the error 'Invalid Argument'
Anyone got any ideas of where I can start to get this problem resolved.
Thanks for reading.

XenCenter is skimpy on the error messages. Try via CLI and see if you can make more sense of the error message. http://www.schirmacher.de/display/INFO/How+to+reattach+a+disk+to+XenServer
