The same device peripherals can be operated in native mode and in VM2000. VM2000, the monitor system and all of the guest systems know and manage the same device peripherals.
Information on generating, configuring and determining device peripherals is provided in the section "Generating and configuring the device peripherals".
Devices and pubsets
From the set of available devices, VM2000 assigns individual devices or the devices of a pubset to the virtual machines.
The VM2000 administrator obtains detailed information on the device properties and on the assignment of devices to the VMs using /SHOW-VM-DEVICE-STATUS. The VM administrator obtains information on the devices of his/her VM using /SHOW-VM-ATTRIBUTES.
Devices
Detailed information on devices and their management in BS2000 is provided in the “Device management” chapter of the “Introduction to System Administration” [2].
Information on managing individual devices under VM2000 is provided in the section "Assigning and removing devices of a VM".
Pubsets
Pubsets (public volume sets) are sets of public disks which, in addition to the private volumes, are the storage locations for files in BS2000. Pubsets contain not only the actual files, but also all the metadata required for file management (e.g. device configuration, file catalog, user catalog). Pubsets are distinguished by their categories (e.g. home, user, shared pubset) and their types (SF and SM pubset).
Detailed information on pubsets and their management in BS2000 is provided in the “Pubset-Management” chapter of the “Introduction to System Administration” [2].
The product HIPLEX MSCF is required for shared pubsets and XCS pubsets, see the “HIPLEX MSCF” manual [10].
In the device management and information commands of VM2000, pubsets can be addressed by means of their catalog ID or their pubres device. VM2000 determines the devices which belong to the pubset and executes the command for all devices of the pubset, see the section "Assigning and removing pubsets of a VM". When the pubset devices are assigned to a VM in this way, VM2000 reacts automatically to changes in the pubset configuration, adapting the assignment and usage mode and the attributes of the devices concerned as needed.
The VM2000 administrator can also manage the devices of the pubset individually, e.g. assign them to the VMs. Changes in the pubset configuration must then be entered manually by the VM2000 administrator. This procedure is not very user-friendly, but also possible.
