Upgrade EFA in a Multi-node Deployment

With EFA 2.3.0 and later, you can upgrade EFA in a multi-node, high-availability deployment.

About this task

Expect the upgrade process to take approximately 10 minutes, during which EFA services are down but users or automated systems can continue to make calls into EFA.

The upgrade process also backs up the EFA database, so that you can easily recover data if the upgrade fails.

Procedure

Download the image (*.tar.gz) to a new sub-folder.
Untar the image.
```
device# tar -xfz efa-v2.x.x.tar.gz
```
Verify the PGP signature as described in article 48172 on the Extreme Portal.
Change to the EFA directory.
```
device# cd efa
```
Run the deployment script.
```
device# source deployment.sh
```
The EFA Installer begins in a series of dialogs.
When prompted, select Upgrade or Redeploy.
The upgrade proceeds. Messages describe the progress and indicate when the upgrade is complete.
Verify the status of EFA after the upgrade.
```
device# efactl status
```
