IBM TotalStorage DS Storage Manager
The IBM TotalStorage DS Storage Manager is a program interface that is used to
perform logical configurations and Copy Services management functions.
The DS Storage Manager program is installed as a GUI (graphical mode) or as an
unattended (silent mode) installation for the supported operating systems. It can be
accessed from any location that has network access using a Web browser. It offers
you the following choices:
Simulated configuration
You install this component on your PC or the Master Console which
provides the ability to create or modify logical configurations when your
storage unit is disconnected from the network. After creating the
configuration, you can save it and then apply it to a network attached
storage unit at a later time.
Real-time configuration
This component is preinstalled on your HMC. It provides you the ability to
create logical configurations and use Copy Services features when your
storage unit is attached to the network. This component provides you with
real-time (online) configuration support.
DS command-line interface
The IBM TotalStorage DS Command-Line Interface (CLI) enables open systems
hosts to invoke and manage FlashCopy and Metro and Global Mirror functions
through batch processes and scripts.
The command-line interface provides a full-function command set that allows you to
check your storage unit configuration and perform specific application functions
when necessary.
The following list highlights a few of the specific types of functions that you can
perform with the DS command-line interface:
v Check and verify your storage unit configuration
v Check the current Copy Services configuration that is used by the storage unit
v Create new logical storage and Copy Services configuration settings
v Modify or delete logical storage and Copy Services configuration settings
Note:
You cannot install the DS CLI on a Windows 64-bit operating system.
DS Open application programming interface
The DS Open application programming interface (API) is a nonproprietary storage
management client application that supports routine LUN management activities,
such as LUN creation, mapping and masking, and the creation or deletion of RAID5
and RAID10 volume spaces. The DS Open API also enables Copy Services
functions such as FlashCopy and Remote Mirror and Copy (formally known as
peer-to-peer remote copy).
The IBM TotalStorage DS Open API helps integrate DS configuration management
support into storage resource management (SRM) applications, which allow
customers to benefit from existing SRM applications and infrastructures. The DS
Open API also enables the automation of configuration management through
customer-written applications. Either way, the DS Open API presents another option
