iSCSI: First burst as immediate data

[Subrahmanya Sastry K V <skotra@npd.hcltech.com>]

Hi all,

I've a doubt regarding the action to be taken by the initiator given the following scenario :

Assume that the target and the initiator have agreed upon the following text parameters:

InitialR2T=Yes
ImmediateData=Yes
FirstBurstSize=64KB
MaxRecvPDULength=8KB (of the target)

The draft(11) says that if InitialR2T=Yes and ImmediateData=Yes then only immediate data are accepted in the first burst.If the FirstBurstSize is more than the MaxRecvPDULength of the target as shown above, how can the entire first burst size of data be sent as only immediate data? As per the negotiated parameters,in this case one cannot use unsolicited Data-Out PDUs to send the first burst.

Any clarifications please ?

Regards,
Sastry
