Cannot discover secondary chassis

[Alex S.]

EDIT: FIXED!

Hello everyone,

I have two UCS 5108 AC2 chassis. One contains 6324 IOMs and the other contains 2204XP extenders. Connected between the two is two QSFP-H40G-CU1M (scalability 40g qsfp+ to 4 10g breakouts). All the links status shows as up on the 6324 IOMs side. 

Using a 1 link discovery policy, I cannot discover the other chassis. I have updated all the firmware to the latest, even UCS Manager 3.1, but I do not see any transient errors regarding the secondary chassis. 

Turns out, all of the Firmware was not 3.1. The 6324 IO Modules were still running 3.0. After updating, I was able to discover the chassis just fine. Thank you all for your help.

Here are my discovery policy settings for the chassis side:

Chassis/FEX Discovery Policy

Action: 1 Link

Link Grouping Preference: None

Rack Server

Action: immediate

Scrub policy: <not set>

Rack Management Connection Policy

Action: Auto

Power Policy: Grid (All 8 PSUs are plugged in and powered on)

MAC Table Aging:

Mode Default

Global Power Allocation Policy:

Policy Driven Chassis Group Cap

Firmware Auto Sync Server Policy

Sync State: User Ack

Global Power Profiling Policy

Profile Power (Checked)
Info Policy: Action - Disabled

Please let me know of any other details I can provide to discover the secondary chassis.

I also understand that the scalability port must be licensed in order for it to be used. Does the grace period count? Or do I need an actual license?

[Walter Dey]

You have to license the port; however, that's not the problem; grace period will start, and even if it expires, it wouldn't remove the configuration.

Could it be a simple issue ? are you connecting the correct one of the 4 available cables ? I would try to connect all 4 and see if it works.

Thank you for your reply Walter. I would imagine it is a simple configuration issue. 

All 8 cables are plugged in on the 2204XPs, however.

Doing show interface command , you can know the status

Connect UCS Mangeer via CLI

# scope eth-server

# show interface

Hi Alexs

Did you configure the server port ? 

I see extended chassis  in our environment .

1. I connected between scalability port and secondary chassis

2.configure the ciscovery policy

3.set server port

our license is as follows

# scope license

# show feature

License feature:
    Name                      Vendor Version Type               Grace Period
    ------------------------- ------ ------- ------------------ ------------
    ETH_PORT_ACTIVATION_PKG   cisco  1.0     Counted                     120
    SCAL_ETH_PORT_ACTIVATION_PKG   cisco  1.0     Counted                     120

Thank you for you reply Kashima,

The ports are configured as server ports, and my licenses feature output looks similar. Very interesting.
