Description

rcxadm server is the command used to control server resources. This function provides the following functionality:

- Display of server statuses (physical OS, VM host, or VM guest)

- Startup, shutdown, or restart of a designated server (physical server, physical OS, VM host, or VM guest)

- Switchover, failback, or takeover of a designated server (physical OS or VM host)

- VM guest migration

- VM maintenance mode settings for VM hosts

- Migration to VM Home Position

- Change the boot agent of the specified server (physical server)

When stopping or restarting a VM host, any VM guests that are running will also be stopped.

Verify that stopping the affected VM guests will not cause any problems before stopping or restarting a VM host.

For details on the switchover, failback and takeover operations, refer to "Chapter 8 Server Switchover Settings" of the "User's Guide VE".

For details on VM guest migrations, refer to "7.1 Migration of VM Guests between Servers" of the "Operation Guide VE".
