[storm] I_T nexus identifier editorial

[Mallikarjun Chadalapaka <[e-mail]>]

In responding to editorial comments on iSCSI-SAM-4 draft, I have just
noticed a related editorial in the consolidated draft that dates back to RFC
3720.

I_T nexus - a relationship between a SCSI Initiator Port and a
SCSI Target Port, according to [SAM2]. For iSCSI, this
relationship is a session, defined as a relationship
between an iSCSI Initiator's end of the session (SCSI
Initiator Port) and the iSCSI Target's Portal Group. The
I_T nexus can be identified by the conjunction of the SCSI
port names or by the iSCSI session identifier SSID. iSCSI
defines the I_T nexus identifier to be the tuple (iSCSI
Initiator Name + 'i' + ISID, iSCSI Target Name + 't' +
Portal Group Tag).

The parenthetical expression at the end should really have four commas in
it:

(iSCSI Initiator Name + ',i,' + ISID, iSCSI Target Name + ',t,' + Portal
Group Tag).

This is how the mapping table captures the nexus identifier in the
iSCSI-SAM-4 draft.  And it'd be good to have consistency between the two
drafts.  I am assuming it'd be possible to make this tweak during the
authors' 48 hour review before the publication (David/Tom?)

Thanks.
