iSCSI does have the ability to communicate additional paths that a client
may choose to invoke, the issue then largely becomes locking across paths,
which becomes a huge issue if lun locking is being used as part of
something like a clustered file system. Of course, most initial initiators
may not be able to support this, and as far as I'm aware what iscsi
initiators that we can control in hardware don't have or have limited iscsi
multipath support. Of course, if they iBFT load that.... Well, I'll stop
now because of limitations with iBFT. :)
