Scsi Miniport: Throttled at 26 outstanding commands

NTDEV
1

I have an issue where no matter how many LUNs I have, and although I
believe that I am using ScsiPortNotification( NextRequest…) and
ScsiPortNotification( NextLuRequest…) correctly, I cannot get more than
26 outstanding commands from Scsi port.

Has anyone seen that before? Can anyone suggest values, fields, or
functions to look into to figure out why ScsiPort thinks he needs to stop
at 26 commands?

Thanks,
e.
