Hi, I wonder whether heartbeat can utilize a shared disk via FC to increase the redundancy of its heartbeat. Actually, I was almost convinced that this is implemented already.
Consider the following setup: - two datacenters hosting a server and a SAN each - a (highly available) network connection between the datacenters/servers - no serial connection - EVMS and heartbeat v2 to manage the disks - (stonith via another virtual network and HP-iLO) A LUN on each SAN is visible (via multipath) to both servers (in both datacenters) and so it will prevent a split brain in case the (highly available) network does not deserve its attribute at some point in time. Especially, because the iLO access might be faulty as well if more than the virtual network is lost. I'd like to use an additional shared EVMS volume or some (remote-) HBA-Feature for heartbeat communication between the servers - actually, just using the FC connection for communication as well. Of course, I don't mean or even activate the local HBA-heartbeat since failover between HBAs is managed by multipath. The HBAs are two Emulex 9802 (targets are mapped with lpfc) connected to LUNs at a local and a remote IBM DS8300 SAN. If heartbeat over disk is possible (like diskhb with HACMP for AIX) I would be greatful to get some hints.
