Upgrading and Uninstalling I/O Filter
Veeam Backup & Replication allows you to upgrade or uninstall I/O filter from clusters using the Veeam Backup & Replication console.
To upgrade or uninstall the I/O filter from clusters:
- Make sure that you have disabled or deleted all CDP policies as described in the Disabling and Deleting Policies section.
- [When uninstalling the filter] If you have manually assigned the Veeam CDP Replication storage policy to VMs that are parts of the clusters, or replicas are still present in the Veeam Backup & Replication configuration database, you must change the storage policy for these VMs.
For more information on how to change storage policies, see VMware Docs. To see the list of replicas, open the Home view. In the inventory pane, click the Replicas node.
- If VMware vSphere Distributed Resource Schedule (DRS) is disabled for the clusters, place the hosts of the clusters in the maintenance mode.
You can simultaneously place all hosts in the maintenance mode or place them one by one for each cluster. Veeam Backup & Replication will uninstall/upgrade the filter only on the hosts in the maintenance mode. That is why you must repeat the procedure (place a host in the maintenance mode and launch installation/upgrade) for each host in a cluster. When Veeam Backup & Replication uninstalls/upgrades the filter on the last host in the cluster, it also uninstalls/upgrades the filter on the cluster.
If DRS is enabled and the hosts use the shared storage, you do not have to put hosts in the maintenance mode manually. VMware vSphere will automatically place hosts in the maintenance mode one by one and migrate VMs from one host to another.
- Follow the instructions provided in the Installing Filters section. At the Clusters step of the wizard, do the following:
- To upgrade the filter, make sure that check boxes are selected near the necessary clusters.
- To uninstall the filter, clear the check boxes near the necessary clusters.
If the upgrade attempt has failed, fix the problems listed in the wizard and launch the upgrade again. During the next upgrade operation, you may see the following error: "The specified key, name or identifier 'vibUrl' already exists. The VIB contains the same filter as the one to be upgraded". If this is the only error, it can be ignored. The error is shown because during the previous upgrade filters were already upgraded on some components. The remaining components are upgraded on the current run. To make sure that upgrade completed successfully, launch the upgrade wizard once again.
As an alternative, you can uninstall the I/O filter from a specific cluster. To do this, open the Inventory view. In the inventory pane, navigate to the Virtual Infrastructure > VMware vSphere > vCenter Servers > <vCenter Server Name> > <Cluster Name> node and right-click it. Select Uninstall I/O filter.
