There are two levels of removing the OS monitoring feature with this command. If you don't specify the uninstall keyword, the OS monitoring feature remains installed on the provisionable server, but the feature is no longer supported and the server's OS can no longer be monitored with N1 System Manager. If you specify the uninstall keyword, the OS monitoring feature is uninstalled from the provisionable server and consequently the OS monitoring feature is no longer supported. Once removed in either instance, the OS resource health state for the server becomes uninitialized.
When you remove the base management feature, the feature is uninstalled from the provisionable server and it is no longer supported. The OS monitoring feature must be uninstalled from a server before the base management feature can be removed.
After you remove a feature, you can always use the add server command to add it back again. The Base Management Supported and OS Monitoring Supported fields in the show server output provide the current status on a server's features.
