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

[fletch2007]

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?

[fletch2007]

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?

[fletch2007]

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
