Install EFA on TPVM for High Availability

Beginning with EFA 2.3.0, you can install EFA on a TPVM (Third-Party Virtual Machine) in a two-node deployment for high availability.

Before you begin

The EFA tar file must be available on the /efaboot partition of the SLX device. You need root access to the device.

About this task

EFA on TPVM is supported only on the platforms described in Supported Platforms and Deployment Models.

The installation process prompts you to select secure mode or standard mode. For more information about these modes, see EFA Installation Modes.

Installing EFA on a TPVM in a two-node deployment takes approximately 20 minutes.

Procedure

Verify that the TPVM is set up for an EFA deployment.
1. Verify the versions of TPVM and SLX-OS.
  For the latest supported version information, see Supported Platforms and Deployment Models.
```
device# show tpvm status
device# show version
device# lsb_release -a
```
2. Verify that the TPVM has an assigned IP address.
```
device# show tpvm ip-address
```
3. Verify that the SSH keys are uploaded.
```
device# show tpvm status
```
4. Verify that passwordless access is configured.
```
device# show tpvm status
```
5. Confirm NTP on the TPVM.
```
device# tpvm config ntp add server <ip>
```
6. Verify that NTP is synchronized.
```
device# show tpvm config ntp 
```
7. If necessary, log in to TPVM and configure the NTP time zone.
```
device# tpvm config timezone
```
8. If necessary, configure unique TPVM host names.
```
device# tpvm config host
```
Enter SLX Linux mode.
```
device# start-shell
# cd /efaboot
```
Copy the EFA tar file to the SLX device.
```
# scp efa-x.x.x.tar.gz
```

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.

When prompted, select Multi-node deployment and OK.

Tip
Use arrow keys to move between options and the space bar to select an option.
When prompted, select Enable secure mode or Standard mode and OK.
When prompted, enter the peer IP address or FQDN of the other node in the cluster.
When prompted, enter the virtual IP address for the cluster.
The installation proceeds. Messages describe the progress and indicate when EFA is deployed.
Verify the installation.
1. On the SLX device, run the show efa status command to see details of the installation and the state of services.
2. From the EFA command line, run the efactl status command to see the status of nodes, pods, and services.
