Upgrade I/O Filters in a Cluster

Use installers provided by I/O filter vendors to upgrade I/O filters deployed in an ESXi host cluster.

An upgrade consists of uninstalling the old filter components and replacing them with the new filter components. To determine whether an installation is an upgrade, vCenter Server checks the names and versions of existing filters. If the existing filter names match the names of the new filters but have different versions, the installation is considered an upgrade.

Prerequisites

• Required privileges:Host.Config.Patch.

Procedure

1. To upgrade the filter, run the vendor-provided installer.
   During the upgrade, vSphere ESX Agent Manager automatically places the hosts into maintenance mode.
   The installer identifies any existing filter components and removes them before installing the new filter components.
2. Verify that the I/O filter components are properly uninstalled from your ESXi hosts:

Results

After the upgrade, vSphere ESX Agent Manager places the hosts back into operational mode.
