E.5 Upgrade the Host Image
Arista provides an ISO with all updated packages and a tool to mount the images ISO and upgrade the
system.
Make sure you use the correct upgrade procedure based on your current CV Appliance configuration.
The two basic upgrade procedures are:
• Single-node configurations .
• Multi-node configurations .
E.5.1 Single-node configurations
Use the following procedure to upgrade a single-node CV Appliance configuration.
Note: Allow 20 minutes for the CVP application to be accessible again after the CV Appliance
host comes up. The CV Appliance host will come up after the system reboots (running the
upgrade script, which is done near the end of the procedure, automatically reboots the system).
Complete the following steps to upgrade single-node CV Appliance configurations.
1. Go to arista.com .
2. Download the mfg tgz tools (
arista-cv-<version>-mfg.tgz
).
3. Extract
tar -xvf arista-cv-<version>-mfg.tgz
. This ensures you have the new version of
upgradeCva.py.
4. Download the update ISO.
5. Run the upgrade CV appliance tool.
