Hi,
Our company is developing our product with generic scsi interface on
the Linux.
We have some options to improve the current generic scsi interface.
(1)
Generic scsi driver will inquire every device on every scsi
bus. If the device replies with device type "1f", it will consider the
device is not present. It is not convenient for us to send a command to
our adapter to do configuration. Currently we lie to OS. we reply it
with device type "3"(processor device type). Maybe it will cause some
side effects.
I hope this limit will be removed.
(2)
Generic scsi driver will not renegotiate with the device when it
get a check condition when the device is reset.
If i send a inquiry command to the device which was reset
previously, it cause OS hang and after the time is expire, the generic
scsi driver will reset the scsi bus and regotiate with device.
About this, i have no option. Maybe the scsi driver interface
should provide a method to do this. Or the generic scsi driver will do
negotiae again after the device is reset.
