Changing the configuration of devices via X2000 (SU x86)

The configuration of the devices managed on the SU x86 by X2000 can be changed during ongoing VM2000 operation using the SE Manager, see the “Operation and Administration” manual [19].

1. Adding new devices
   When it has been physically connected, the new device is defined and parameterized. The new device is reported by X2000 and is automatically recognized by VM2000, the monitor system and all guest systems. The VM2000 administrator is informed of this with the message VMS4065. The VM2000 administrator can then assign the new device to a VM, e.g. with /ADD-VM-DEVICES.

2. Changing device properties
   When use of the device concerned has been prohibited in all guest systems by detaching it with /DETACH-DEVICE, the device properties can be changed. In this case the device must be removed from the VM only if its mnemonic device name changes. When the device properties have been changed, the device can be attached again to the guest system with /ATTACH-DEVICE.

3. Removing devices
   The device concerned should be detached from all guest systems beforehand and removed from the VM with /REMOVE-VM-DEVICES. The relevant device is made invalid in the configuration of VM2000, in the monitor system and all guest systems.

The adding and removing of devices is immediately taken into account by the monitor system and all active guest systems.
