VMware vSphere • Re: Veeam IO Filter Upgrade

Hi Lewisf

did not do the upgrade because there were questions regarding how many hosts would be affected and if any of the hosts would be affected,

I/O filters are installed on every ESXi host in a cluster. Therefore they need to be updated on every host. Use the I/O Filter Management Wizard to check which cluster have the I/O filters installed.

if the hosts would have to be put in maintenance mode,

Yes, they have to put into maintenance.

and if any hosts would need to be rebooted.

No, they won't be rebooted. But during maintenance on the host, all virtual machines must either be temporarily suspended or migrated to another ESXi host.
If you have DRS enabled and your hosts use Shared Storage, this can happen automatically one by one. If not, you need to enable maintenance host for one host and let Veeam update the I/O filter. Then disable maintenance mode for that host. Repeat the procedure for all other hosts.
