sbp2port.sys, SCSI Passthrough - Unsolicited Target Status

NTDEV
1

Hi Folks,

I am current looking into using the SBP2PORT.sys driver as a SCSI pass
through for a device we are implementing.

The actual Protocol we will be using needs to have support for Asynchronous
event notification from the device.

From what I understand, the SBP2 Protocol supports this via the initiator
setting up the UNSOLICETED_STATUS_ENABLE register. If the target needs to
notify the host of some kind of status, it writes to this register. This
results in the CSR register being updated on the host SBP2Layer. Under
normal, direct SBP2 implementation, the host/initiator application would
register a callback at SBP2 login to be notified of this event.

Is there a way to accomplish this via SCSI pass-through mechanisms over
SBP2PORT.sys ?

Thanks

IIRC async event notification is not supported properly even in
SCSIPORT, not to say in SCSI over-something implementations.
