Re: Sense data and Response Data

["Eddy Quicksall" <ESQuicksall@hotmail.com>]

MessageDid anyone get back to you yet? As I see it, you do the following:

Send the data as SCSI READ Data (op/code 25) and S bit set to 0. Then send
the sense data as SCSI RESPONSE (op/code 21), the S bit set to 1, the status
set to CHECK CONDITION, the DataSegmentLength set to the length of the Sense
Data and the Sense Data to follow that.

Subject: Sense data and Response Data


In SCSI Response PDU, the target can send either Sense Data or Response
Data, but not both. In certain cases, such as when a filemark is detected on
the tape during read, the target needs to  return both the data read before
reaching the filemark and the sense data.

Is there anyway targets can do this?
thanks!
