Hi Mike Just want to point out that the previous mail from Larry (llw3) was the response from Qlogic on this subject (Larry works for Qlogic). This is a decision driven by QLogic. I agree that its hard to see full range of issues without having access to qlogic development docs. But as stated by Larry, the firmware differences do inhibit us from doing a comstar target mode support for 2G adapters using the qlt driver. Hopefully Qlogic will respond to your post to explain it further.
