I agree with Dennis.

I think though that Paul is right that these keys should NOT be used as an
excuse to permit interoperability problems. They can though be
informative. If a customer has problems with my code, I'd love to have
revision info, which could be conveniently conveyed with these keys.

As to the poster this morning (whose message I deleted too fast) who said
this is wrong because the info should be available in SCSI sense data, I
disagree. Consider the case of an iscsi->parallel scsi gateway (a box that
has a traditional scsi drive, and exports it over iSCSI). There the scsi
sense data & mode pages are (well might be) those of the attached drive,
which can be from a different vendor than the iscsi device.

Also, don't forget we're talking about an optional thing (they are X-keys
after all). :-)

Take care,

Bill
