Hi Andy, That's exactly what I did. I played around with it for a while until stumbling on that solution. Works great now!

Try just creating one TPG object. For each StorageObject you will then need to add it to the tpg, creating a LUN object. Add a NodeACL to the TPG for each initiator, and for each NodeACL, create a MappedLUN to give the NodeACL access to the tpg LUN. So it's a bit of a two-step process for fabrics that support ACLs. It makes more sense given that all fabrics don't support ACLs. For those, they just add the StorageObject to the TPG. But for fabrics that have initiator ACLs, they do that, and then also need to grant access to the TPG LUN by a given NodeACL with the MappedLUN. so if you want to map a single storageobject to multiple initiators: target = Target(fabric) tpg = TPG(target) lun = LUN(tpg, lun=0, so=so) for init_wwn in initiator_wwns: node_acl = NodeACL(tpg, init_wwn) mlun = MappedLUN(node_acl, lun) Hope this helps -- Regards -- Andy -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html ________________________________ NOTICE: This e-mail and any attachments is intended only for use by the addressee(s) named herein and may contain legally privileged, proprietary or confidential information.
