RE: iSCSI: Question on SCSI INQUIRY response

["Asai Thambi S.P - CTD, Chennai." <sp_asai@ctd.hcltech.com>]

The target can send the status in the last SCSI Data-In

PDU with S bit set and need not send the SCSI response

PDU for that request.

 

The data segment of SCSI response PDU can only contain

sense data and/or response data (vendor specific info).

 

So the actual (I/O) data can not be part of the data segment

of a SCSI response PDU.

Subject: iSCSI: Question on SCSI INQUIRY response

Hi All,

Suppose I've sent an INQUIRY CDB as a part of SCSI request PDU
to the target, waiting for the INQUIRY response data. Is it legal to
get the same as part of data segment of SCSI response PDU(with
SCSI status GOOD)?
or should it be got  ONLY as part of data segment of a Data-In PDU
( with S bit set to 1)?

Please clarify !

Sastry
