You are correct in that in order to have the multi-pathing on the PS6000 you will need to install the HIT Kit. Version 4.5 is the latest and that is the one that we recommend that you install. If you log into the support site and go to the download section for the HIT Kit and scroll down there is a documentation section for the HIT Kit and you will see the install and user guide that you can download. It walks you through the entire process on what you will need to do in order to get it installed and configured. Please take a look at that document and feel free to let me know if you have any other questions.
Hello, I just wanted to verify that I do in fact need the HIT Kit to do MPIO with a PS6000.  Currently without the HIT Kit tools, I can see 1 path via my iSCSI initiator on my 2008 R2 server.  The target I am discovering is the group IP.  My understanding of how this works is, the group IP is a virtual IP, with the other IPs on Eth 0-3 behind that.  I am single pathing to the group IP now without the tools, but after I install the tools... I will see what?  All the IPs behind the group IP?  Or will the tools handle the multi-pathing (2 physical NICs in the server going to the iSCSI network with the CM eth cables connected as well).  This is the document that I am working off now [URL]  Thanks.
