Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document describes the Fabric Interconnect firmware auto-sync feature of the Cisco Unified Computing System (UCS). This feature can be used when introducing a second Fabric Interconnect (FI) to the existing one or when replacing a broken FI.

Prerequisites

Requirements

Cisco recommends that you have a working knowledge of these topics:

Cisco Unified Computing System (UCS)
Cisco Fabric Interconnect (FI)

Components Used

The information in this document is based on these software and hardware versions:

Cisco UCS Fabric Interconnect 6248
Cisco UCSM versions 2.2(5a) and 2.2(6c)

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

About the feature

When you introduce a second Fabric Interconnect to the existing one to form a cluster or when you replace a broken Fabric Interconnect, the firmware version on the new FI needs to match with the existing one.

The usual procedure is to configure the new FI as standalone and upgrade or downgrade it manually to the same version as the existing FI before adding it to the cluster.

Starting with UCSM 2.1(2), the firmware auto-sync feature will automatically upgrade or downgrade the new FI to the same version as the existing one. This eliminates the requirement of manually upgrading or downgrading the FIs.

The existing FI needs to be at UCSM 1.4 or later and the new FI needs to be at UCSM 2.1(2) or later for this feature to work. Also, the FIs need to be of the same model for this to work.
