I am aware of the following Dual-port target device behaviors:
1) Target device will export lun(s) and accept commands on only
one port at a time.
2) Target device will export lun(s) on both ports, but both ports
will NOT accept commands equally.
3) Target device will export lun(s) on both ports, and both ports
are will accept commands equally.
It would be nice if the SCSI initiator driver could discover
which dual-port model is being implemented at the target device.
I think the Standard Inquiry MultiP bit may be used to distinguish
(1) from (2 & 3). Though, I don't think (2) and (3) can be distinguished
|from each other.
Comments ?
Regards,
Larry
