If opening an iSER connection is what you want, why wouldn't you try to open an iSER connection from the start. If the question is how do you locate targets (or ports) which provide iSER storage services, then it's a separate question to be answered by using and/or augmenting SendTargets, SLP, iSNS and related discovery mechanisms. There have been some discussions of it in IETF-IPS. > And some questions: I was confused with the > 'Allocate_Connection_Resources'. It allocates resources for iSER > connection. But the connection has been established at the beginning. The purpose of 'Allocate_Connection_Resources' is to allocate resources, not to establish connection. Some allocation/operation parameters may depend on the outcome of the login phase (negotiated values of some iscsi/iser operational parameters), so it is ok to call it even if the connection is already established. Note that the login phase has some very strict limitations on what can actually be sent or received, so 'Allocate_Connection_Resources' actually gives you a chance to do all necessary preparations for the "real" work.
