Table 1: Changes

Newly added commands and functions

Command	Function / Comment
MOVE-DISK	Expand / reduce pubset and initialize disk. The function is available from BS2000 OS DX SP 20.2.

Table 2: New commands

Omitted commands and functions

From BS2000 OS DX onwards, the components GSMAN, GSVOL and SPACEPRO are omitted. Consequently, the commands for these components are omitted as well (commands with the partial name “GS” or “SPACEPRO”, e.g. ATTACH-GS-UNIT or MODIFY-SPACEPRO-PARAMETERS) and therefore no longer described in the manual.

The commands MODIFY-LIVE-MIGRATION-DEFAULTS and SHOW-LIVE-MIGRATION-DEFAULTS are no longer supported.

Since BS2000 OS DX only supports connection via Fibre Channel from V11.0 onwards, the operation of SPD disks is no longer supported (SPD disks were only supported on the type S channel). 

Notes on the SE server

The released versions of the BS2000 operating system supports the SE server's Server Units

Name of the Server Unit	Architecture	Periphery type
Server Unit /390 (SU /390)	/390 architecture	Channel peripherals
Server Unit x86 (SU x86)	x86-64 architecture	Bus peripherals

On the SE server the device peripherals are only supported via Fibre Channel. Type 2 and type S channels are not supported (exception: virtual console on SU /390).

SE servers have no global storage.

General information

The name of the BS2000 basic configuration has changed and from version V10.0 becomes: BS2000 OSD/BC. Previous versions will be referred to by the previous name BS2000/OSD-BC.

In the command descriptions, the name of the component to which the command belongs is indicated without information on the version. The version overview for the commands has been omitted. 

The device type table for BS2000 is also contained in the "System Installation" manual [46]. The devices currently supported are specified in the BS2000 OS DX Release Notice.

An overview over all system parameters (privileged and nonprivileged) is included with the description of the SHOW-SYSTEM-PARAMETERS command.
