We have a a DRS cluster of 6 esx hosts. One of the hosts (now in maintenance mode) is having problems so my idea was to create a new cluster and move the host to that cluster to do some further testing and troubleshooting so no VM's are migrated to that hosts.
If i move the host to the new cluster (or a folder) will it lose all the configured networks / datastores / etc.. ?
No,you won't lose datastores, or network configurations. The only things that will be different are the cluster settings (HA, DRS, EVC, ...), and permissions (if individually configured on the cluster).
