Support Central: KB #4595: Grid Members Communication Fail To Join Back to Grid

This week, we're bringing you an important KB article you may find helpful if your Grid Members are communicating with the Grid Master.  Specifically communicating through the Management interface with hardcoded port speed and duplex settings, but fail to join back to Grid

 

Problem Summary

Grid Members communicating with the Grid Master through the Management (MGMT) interface with hardcoded port speed and duplex settings will fail to join back to the Grid when  upgrading to NIOS 7.1.x or NIOS 7.2.x from earlier releases.

 

Customer Environment

Infoblox Grid running NIOS versions prior to NIOS 7.1.x or NIOS 7.2.x releases and planning to upgrade to NIOS 7.1.x or NIOS 7.2.x

 

Affected Versions

NIOS 7.1.x and NIOS 7.2.x

 

Cause

This issue is specifically related to Members configured to use the MGMT interface for Grid communications, and that have hardcoded speed and duplex settings. Grid Members using other ports for Grid communications, or that are configured to use auto-negotiation are unaffected.

 

Resolution

If you have Grid Members configured to use MGMT Interface for Grid communication with hardcoded port settings, please change the MGMT interface speed and duplex settings to auto/auto before upgrading to NIOS 7.1.x or NIOS 7.2.x.  This issue will be addressed in future patches.
