I am currently developing an external SCSI-3 target device and I wonder what
to do in case of reset or power off/on of the device.
My device supports PPR negotiation and is correctly detected at 160 MB/s by
a Windows 2000 machine with an adaptec 39160 board. If I reset my device,
the transfer parameters go back to the default mode which is narrow
asynchronous. Is there any way to indicate to the initiator that my target
has been resetted and thus that PPR negotiation has to be performed again ?
What happens now is that the initiator issues an INQUIRY command expecting
the data phase to be synchronous...
Is there something specified in the SCSI standard indicating how the target
should behave ?

Thanks for your help,
