I tried creating a view for a thin lu with my other zfs box, but how do I detect it? First of all, if you run IB, forget the iscsi stuff, it's only creating un unnecessary IP layer that you don't need, and adds latency to your application. Did you create SRP target service using COMSTAR? # svcadm enable -r ibsrp/target What's the output of "srptadm list-target" ?(on storage box), or you can also use "stmfadm list-target -v" Do you got all necessary IB stuff, like a storage manager(OpenSM), in place? HCA ports shows up in dladm show-link? If so, your host system should discover it as a local disk, just with "format", if you have created a view with the right eui.xxxxxxxxxxxx for the initiator HCA.
