Thanks for the reply, Ken.  I can't figure out what might have caused
these iSCSI targets to already be active.  They aren't configured in
targetcli (outside of Pacemaker) and I have no scripts that do anything
like that, dynamically.

I don't have a default-resource-stickiness value set.  Could that have
caused the iSCSI targets to be brought up on the node that was being
brought out of standby?

Thanks!
Bryan
