I don't think John said portal groups are dynamic, he simple said they are not currently *required* to be static. I think it's reasonable to ask that targets use consistent numbering of portal groups across target boots, ie. if a group of addresses are in portal group 1 today, next boot the target should still report them as portal group 1 (unless the address configuration has changed). > Example: I have an initiator with two HBAs.

This is a management task that exists today for initiator implementations - HBA vendors are dealing with it in their "configuration tools" with proprietary interfaces to their HBAs. The change you suggest to "initiator name" is not appropriate - portal groups are only a grouping of IP addresses that can be used for a multi-connection session, they have no association to the construction of "initiator port name" (other than indirectly, thru the session construct). And even if the change you suggest was made, there is no protocol method for "discovering" initiator names - as Jim points out, there is no protocol need for such a thing. Please review the iSCSI MIB and suggest changes the MIB structure which would aid you in your management needs. Marjorie Krueger Networked Storage Architecture Networked Storage Solutions Org.
