Replace a Node in a Multi-node TPVM Deployment

You can use the upgrade process to replace a faulty node in a multi-node TPVM deployment.

Before you begin

Ensure the cluster with the faulty node is running EFA 2.3.0 or later.

Ensure you have completed the high-availability prerequisites in EFA Requirements.

Ensure that EFA is not deployed on the replacement node.

About this task

During this process, the faulty node is decommissioned, the replacement node is provisioned, and the active node is reconfigured to form the cluster.

Perform this procedure on the active node where EFA is installed.

Procedure

  1. Enter SLX Linux mode and copy the EFA tar file to the SLX device. 
    device# start-shell

scp <username>@<hostip>:<buildpath>/efa-3.1.0.tar.gz
  2. Deploy EFA on TPVM from the SLX shell. 
    device# efa deploy
Starting "efa deploy", DO NOT hit CTRL+C
Step 1: Checking if TPVM is deployed ...
Step 2: Get IP Addressed assigned to TPVM to deploy EFA
IP Address of the TPVM 10.x.x.x
Step 3: Checking for EFA packages in /efaboot directory
Step 4: Deploying EFA package efa-2.x.x.tar.gz on 10.x.x.x

    The EFA Installer begins in a series of dialogs.

  3. When prompted, select Multi Node Build Upgrade with Node Replacement and OK.
