Re: Retry question

[Santosh Rao <santoshr@cup.hp.com>]

It looks like Rev 05 does support partial data recovery and the target
can send back either all the data or data starting from EndDataSN on a
"retry" command.

I thought the Orlando consensus was to perform error recovery at command
granularity and not do partial data re-transmission (?).

Quoting from David Black's mail
(http://ips.pdl.cs.cmu.edu/mail/msg03221.html) :

"- DataSN (formerly DataRN) functionality will be removed.  Error
   recovery is now at the granularity of commands, not within a
   command."

Regards,
Santosh
