Uninstall I/O Filters from a Cluster
You can uninstall I/O lters deployed in an ESXi host cluster.
Prerequisites
n
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 dierent
versions, the installation is considered an upgrade.
Prerequisites
n
Required privileges:.
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 identies 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 specic 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 congured, 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.
