Problem Description

Some Cisco M81KR Virtual Interface and Qlogic M71KR-Q CNA mezzanine cards prevent discovery of UCS blades due to an incorrect programming of card type.

Affected units can be identified using the procedure in the 'How to Identify Affected Products' section of this Field Notice.

Background

Several N20-AC0002 and N20-AQ0002 mezzanine cards shipped during July, 2010 were mis-programmed with an incorrect card type. Depending on the UCS Manager version that is running, this can have the effect of making a blade undiscoverable.

Problem Symptom

The problem symptom observed is a UCS blade will not be discovered by UCS Manager if an affected mezzanine adapter is installed. The failure occurs only with certain combinations of UCS Manager and affected hardware.

UCSM release 1.2 and earlier:

N20-AQ0002 will cause the problem
N20-AC0002 will cause the problem

UCSM release 1.3:

N20-AQ0002 will cause the problem
N20-AC0002 will not cause the problem

The following example shows a Cisco M81KR Virtual Interface with UCSM version 1.2 failing discovery:

The following example shows a Qlogic M71KR-Q CNA failing discovery:

Workaround/Solution

First, confirm whether you have affected N20-AC0002 or N20-AQ0002 mezzanine cards using the procedure in the 'How to Identify Hardware Levels' section.

If N20-AC0002 (UCS M81KR Virtual Interface) is the only affected mezzanine card, you may use option A or B below:

Use UCS Manager release 1.3 or higher.
Use UCS Manager release 1.2 after running the FixFrus Debug Plug-in procedure described farther below.

If N20-AQ0002 (M71KR-Q QLogic CNA) is among the affected mezzanine cards, you should use UCS Manager release 1.3, or use UCS Manager release 1.2 after running the FixFrus Debug Plug-in procedure described below.

If you are running UCS Manager release 1.1 and are unable to upgrade for some reason, the affected mezzanine card must be fixed manually. Please contact the Cisco Technical Assistance Center if this is required.

FixFrus Debug Plug-in

This is a debug tool that will check and fix mis-programmed card_type on M71KR-Q QLogic CNA and M81KR Cisco Virtual Interface mezzanine cards identified by this Field Notice.

Supported UCSM Version

This debug plug-in works with versions 1.2(1x) and 1.3(1x) UCS Manager software.

Caveat

To fix a mis-programmed mezzanine interface on a server, the server must be decommissioned manually. This is a service disruptive activity.

How to Use

Download ucs-fixfrus-dplug.1.0.1.0.gbin onto the Fabric-Interconnect. The debug plug-in can be downloaded using the following steps:
1. Navigate to www.cisco.com and log in with your Cisco.com user id.
2. Navigate to Support > Download Software.
3. Select Products > Unified Computing > Cisco UCS Manager > Unified Computing System (UCS) Complete Software Bundle.
4. The FixFrus debug plugin can be found in either the 1.2(1d) folder or the 1.3(1n) folder. The files are named uniquely for each folder but the image is the same i.e. either image will work with either release. The FixFrus debug plugin is named:
```
ucs-fixfrus-dplug.1.0.1.1-1.2.1.gbin

or

ucs-fixfrus-dplug.1.0.1.1-1.3.1.gbin
```
5. Download one of these files and place it in a location accessible to UCS Manager.

Load the plug-in. When it runs, affected mezzaanine cards will be detected and fixed after the user is prompted for verification.
