New 3270: no link on switch from T320E-SFP+ after 7.3.5.1P2 upgrade

Hi - I am staging a new Netapp 3270 with Chelsio Dual  10gig nic connected to an HP 5406zl - but after upgrading from 7.3.5.1P1 to 7.3.5.1P2 and rebooting I am getting no link on any of the 4 ports on the  5406zl side.

(I'm not sure the upgrade was the culprit, but its one of the last changes before the link  on all 4 went down) - previously we had link


When I bring up the nic with ifconfig e1a up, the status changes to  auto-unknown-enabling for a few seconds, then auto-unknown-down)

Netapp:

na04> sysconfig -v 1
slot 1: Dual 10G Ethernet Controller T320E-SFP+
Device Type:        CT-31-3
Version Number:     T3-SRAM1.1.0-BR1114-30-A0-FW7.7.2-DR04
Serial Number:      PT12110481
e1a MAC Address:    02:a0:98:99:50:ea (auto-unknown-down)
e1b MAC Address:    02:a0:98:99:50:ea (auto-unknown-down)

5406zl:
> sho int brief c3,c4

Status and Counters - Port Status

| Intrusion                           MDI   Flow  Bcast
Port   Type      | Alert     Enabled Status Mode       Mode  Ctrl  Limit
------ --------- + --------- ------- ------ ---------- ----- ----- ------
C3     SFP+SR    | No        Yes     Down   10GigFD          off   0
C4     SFP+SR    | No        Yes     Down   10GigFD          off   0

Should I try swapping out the tranceivers?
The weird thing is I was getting link earlier in the day and the switch  was logging up and down entries when I was bringing netapp vifs up and  down during testing - but now nothing - the link is stuck DOWN on the  5406zl.

Anyone seen this after going to P2?
We've tried disabling/enabling, reseating fiber connections - still no LINK.

Thanks for any tips!

If you do a sysconfig -ca or a sysconfig -v are you seeing the correct cards being reported? Do you have light coming out of the cards?

na03> sysconfig -ca
sysconfig: slot 1 OK: X1107A: Chelsio S320E 2x10G NIC

na03> sysconfig -v 1
    slot 1: Dual 10G Ethernet Controller T320E-SFP+
        Device Type:        CT-31-3
        Version Number:        T3-SRAM1.1.0-BR1114-30-A0-FW7.7.2-DR04
        Serial Number:        PT12110496     
        e1a MAC Address:    00:07:43:07:71:1b (auto-unknown-down)
        e1b MAC Address:    00:07:43:07:71:1c (auto-unknown-down)

I need to do the "unplug fiber and shine on white paper test at the switch end" test

thanks!

Have you tried to boot back into P1?

Just downgraded back to P1 and the link is BACK!?

Why would P2 affect this? - no networking related items in the notes I can see

The new 3270 shipment came with  2 different models (AVAGO & Finisar) - we installed 4 AVAGO in the Chelsio card and 4 Finisar in the c0a + c0b x2 interconnect

Turns out it was not compatible - they needed to be swapped
Once they were swapped - LINKS UP!

Back to P2 and we are all good for the upgrade to proceed...

Moral: not all transceivers are equal - check them!

thanks
