Using Srb->QueueTag in a Storport Miniport

NTDEV
1

I have a Storport Miniport driver. I want to do queued commands, and I would like Storport to pick the queue tag for me.

If I set TaggedQueuing to TRUE in my HwInitialization structure during init, will I get what I want by using the value passed to me in Srb->QueueTag as my tag value?

I’m assuming that I also have to pay attention to Srb->QueueAction - but in what way?

With SCSIPORT, you would also need MultipleRequestsPerLU.

Of course - but will I be able to rely on the value passed to me in Srb->QueueTag?
