Re: iSCSI: Questions regarding iSCSI LUN Access Controls

["Mallikarjun C." <cbm@rose.hp.com>]

Nick,

As Jim points out, SPC-3 is the "clearer definition/reference".
iSCSI draft does not include references to numerous individual 
T10 proposals, but rather to T10 standards that incorporate the 
approved proposals.

The only thing I'd recommend is that a reference to SPC-3 be 
added explicitly in the quoted text - i.e. S/b "SCSI access controls"
W/ "SCSI access controls ([SPC3])" on the first reference.
