5420 "unsupported version"

[jmlevy]

Wondering if anyone's seen this one. 5420, 2.1.2 running. Any initiator I try to connect -- Cisco (Windows and Linux), MS, Novell, old versions, new versions, -- is rejected with an "unsupported version" reason. Ethereal trace shows an error 0205 and that the target version max = 2 and the version active = 2, where the initiator proposes 0 in both fields. Same failure occurs with 1.1.5... any ideas?

Thanks!

You are probably trying to use draft 20 drivers on the initiators and the 5420 only understands up to draft 8. The 5428 and 5428-2 began using the draft 20 specifications with the 3.x code. 2.x code is draft 8 and that is the highest the 5420 can run.

This information is documented in the end of sales announcement for the 5420 at:

So I guess the MS initiator is out (even though MS appears to qualify it with the 5420 -- wonder how that's possible...) and I'll need to drop back to an ancient version of the Linux and Windows initiators if I want to see this work. Any chance of a fix appearing? There have to be people out there using 5420s...

Thanks!

If you use the latest 2.x code in the 5420 and latest 2.x drivers, it will work in draft 8 mode. There will be no draft20/3.x 5420 code-only for the 5428 and 5428-2.

AFAIK 2.1.2 is the latest 5420 code (if not, what is?). Is there any way to get the MS initiators down to draft 8?

thx

Yes, 2.1.2 is the last for the 5420. I don't think MS released anything less than draft 20 but you would have to ask them to make sure.

Ouch. Neither the MS nor the Cisco sites seem to have downrev (2.x) code, and there doesn't seem to be anyplace else that has them posted for either MS or Linux. I'm still confused -- Cisco had to have sold a pile of these boxes -- other than seeking out old initiators how is anyone using them?
