You have to add all the initiators for each node to the iscsi LUN.  At least thats how I got it working.  Then I think it's recommended to setup multipath. 

However take this with a grain because iscsi did not work well for me.

When I added the first node a 'random' initiator name was generated of form:

# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:[RANDOM]

Having attempted to add another node, this node has another initiator name generated and can't access the storage. Is there a way to configure this initiator name to a static value which will be configured when new nodes get added to the cluster? Or is there some reason for this i'm missing?

thanks,

Dan
