RE: iSCSI: Last call issues for the Naming and Discovery document

["THALER,PAT (A-Roseville,ex1)" <pat_thaler@agilent.com>]

Mark,

This doesn't seem consistent with the iSCSI (draft-ietf-ips-iscsi-16) use of "address". I can't find anywhere where it calls the address the iSCSI name plus a transport address. For example, in 11.8, it defines target address as:

TargetAddress=domainname[:port][,portal-group-tag]

This doesn't include iSCSI name and it does include portal-group-tag which isn't mentioned in the Naming and Discovery document. To harmonize the two documents, iSCSI address should not include the iSCSI name and the option for portal-group-tag should be added to Naming and Discovery.

Also, the use of Address in the iSCSI draft is asymmetrical. The iSCSI draft only applies the structure of address, <domain-name>[:<port>], to target addresses. Initiator address is generally not mentioned. While the iSCSI protocol doesn't explicitly use initiator addresses, they may be useful for other things such as management interfaces so a target can report address along with who is connected. The Naming and Discovery document should at least explain the difference between the asymmetry in the use of address in iSCSI and the symmetry in Naming and Discovery. One might also mention that a target will be only able to report the address of a connected initiator in one of the IP formats because it doesn't ever receive a DNS based name.

How about (page 5):

   iSCSI nodes also have addresses. An iSCSI address specifies a single
   path to an iSCSI node and consists of the iSCSI name, plus a transport
   (TCP) address which uses the following format:

      <domain-name>[:<port>]

   Where <domain-name> is one of:
