RE: iSCSI SCSI Port Name

[pat_thaler@agilent.com]

Jeff,

It appears that the problem is that section 1.1. ignores details of the format (commas and pad). One way to fix this while still allowing the section 1.1 definition to be brief and keeping the rigorous definition in just on place would be to replace "and is" with "includes", "based on", or "containing" and adding a reference to the detailed description:
In Section 1.1
	SCSI Port Name: A name made up as UTF-8 characters containing the
		iSCSI name, 'i' or 't', and ISID or Portal Group Tag (see 2.4.2)
Perhaps the UTF-8 character part isn't needed at the glossary level of detail.
     SCSI Port Name: A name containing the iSCSI name, 'i' or 't', and ISID 
		or Portal Group Tag (see 2.4.2)

Subject: iSCSI SCSI Port Name


Julian,
In reading 12-96, I came across two different definitions of a
SCSI Port Name.
In Section 1.1
	SCSI Port Name: A name made up as UTF-8 characters and is the
		iSCSI name + 'i' or 't' + ISID or Portal Group Tag
In Section 2.4.2
	SCSI Port Name is mandatory in iSCSI. WHen used in SCSI parameter data,
	the SCSI port name MUST be encoded as:
	- The iSCSI Name in UTF-8 format, followed by
	- a comma separator (1 byte), followed by
	- the ASCII character 'i' (<snip>) or the ASCII character 't' (<snip>), followed by
	- a comma separator (1 byte), followed by
	- zero to 3 null pad bytes <snip>, followed by
	- the 6 byte value of the ISID or the 2 byte value of the Portal Group Tag

I'm assumming the definition in Section 2.4.2 is the "correct definition", and the one
in Section 1.1 needs to be changed to match this definition.
