Uninstall I/O Filters from a Cluster
You can uninstall I/O lters deployed in an ESXi host cluster.
Prerequisites

Required privileges: .
Procedure
1 Uninstall the I/O lter by running the installer that your vendor provides.
During uninstallation, vSphere ESX Agent Manager automatically places the hosts into maintenance
mode.
If the uninstallation is successful, the lter and any related components are removed from the hosts.
2 Verify that the I/O lter components are properly uninstalled from your ESXi hosts:
esxcli --server=server_name software vib list
The uninstalled lter no longer appears on the list.
Upgrade I/O Filters in a Cluster
Use installers provided by I/O lter vendors to upgrade I/O lters deployed in an ESXi host cluster.
An upgrade consists of uninstalling the old lter components and replacing them with the new lter
components. To determine whether an installation is an upgrade, vCenter Server checks the names and
versions of existing lters. If the existing lter names match the names of the new lters but have dierent
versions, the installation is considered an upgrade.

Procedure
1 Run the vendor-providore installer to upgrade the lter.
During the upgrade, vSphere ESX Agent Manager automatically places the hosts into maintenance
mode.
The installer identies any existing lter components and removes them before installing the new lter
components.
2 Verify that the I/O lter components are properly uninstalled from your ESXi hosts:
esxcli --server=server_name software vib list
After the upgrade, vSphere ESX Agent Manager places the hosts back into operational mode.
I/O Filter Guidelines and Best Practices
When you use I/O lters in your environment, follow specic guidelines and best practices.
n
I/O lters do not support RDMs in physical compatibility mode.
n
Flash Read Cache and caching I/O lters are mutually exclusive because both functionalities use the
virtual ash resource on the host. You cannot enable Flash Read Cache on a virtual disk with the cache
I/O lters. Similarly, if a virtual machine has Flash Read Cache congured, it cannot use the cache I/O
lters.
n
You cannot change or assign the I/O lter policy when migrating or cloning a virtual machine.
