In chapter "Storage systems in BS2000" the manual describes the basic functions and how the storage systems are connected to the BS2000 servers and to the BS2000 operating system.
The chapter "Software product SHC-OSD" provides an overview of the SHC-OSD product and StorMan. The functions of SHC-OSD are implemented using commands. These are described in the chapter "Commands".
The chapter "Overview of the replication functions" is followed by a description of the storage systems' various replication functions and their use with SHC-OSD in BS2000.
The provisioning functions of the storage systems are described in the chapter "Thin provisioning".
The functions of Automated Storage Tiering (AST) are described in chapter "Automated Storage Tiering".
The functions of Storage Cluster Option (SCO) are described in chapter "Storage Cluster Option".
At the end of the manual you will find various lists which are designed to make it easier for you to use the manual.

Terminology used and explanations
The term storage system (previously also called disk storage system or disk storage subsystem) refers to an ETERNUS DX or ETERNUS AF storage system.
The terms unit and device each refer to a logical volume (logical disk) and a physical disk (physical device) in the storage system.
The term replication function (previously also called: mirroring function) refers to the functions of the storage systems which mirror all or some of a unit's data to another local or remote unit. See also the chapter "Overview of the replication functions".
The terms original unit and source unit in a replication function refer to the unit on which the data of an application is originally stored.
The terms clone unit, snap unit and target unit refer to the units to which the original data is mirrored.
In SHC-OSD commands the UNIT operand is used to define the (logical) volumes of the storage systems. In most commands one of the following can be specified for UNIT:
MN (mnemonic device name of the logical volume in BS2000)
VSN (Volume Serial Number)
Pubset ID or volume set ID (ID of an SF/SM pubset or ID of a volume set)
Serial number of the storage system and internal number of the logical volume in the storage system
One or more logical volumes can therefore be specified for UNIT.
