Re: iSCSI: One Node or Two?

It is possible that this 2 way target has two different Names.  However,
since the SCSI Initiator Port is a dynamically created entity, and the only
unique part of its ID (within the Initiator Node) is its ISID,  there is no
reason there has to be a different iSCSI Node Name.

An implementation, however, could create a node that is uses for all iSCSI
Initiator functions,  however, there is no hard reason for that, and
depending on how it is named it may either be more or less confusing to the
Administrator.

Subject:    iSCSI: One Node or Two?



As defined in the latest draft an iSCSI Node "... represents a single iSCSI
initiator or iSCSI target."

By this definition an LU that acts as both an initiator and a target, such
as a data mover for extended copy, is two iSCSI nodes.  This LU will have
two iSCSI names, one for the initiator side of the LU and one for the
target.  Therefore, there will be two  iSNS "entries" for this LU.

My question is: Is this intended?
