DS6000 Series: Concepts and Architecture

The DS open application programming interface (API) is a non-proprietary storage 
management client application that supports routine LUN management activities, such as 
LUN creation, mapping and masking, and the creation or deletion of RAID-5 and RAID-10 
volume spaces. The DS Open API also enables Copy Services functions such as FlashCopy 
and Remote Mirror and Copy. It supports these activities through the use of the Storage 
Management Initiative Specification (SMIS), as defined by the Storage Networking Industry 
Association (SNIA).

The 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 for managing the DS6000 by complementing the use of the IBM 
TotalStorage DS Storage Manager Web-based interface and the DS Command-Line 
Interface.

You must implement the DS Open API through the IBM TotalStorage Common Information 
Model (CIM) agent, a middleware application that provides a CIM-compliant interface. The 
DS Open API uses the CIM technology to manage proprietary devices such as open system 
devices through storage management applications. The DS Open API allows these storage 
management applications to communicate with a DS6000.

IBM will support IBM TotalStorage Multiple Device Manager (MDM) for the DS6000 under the 
IBM TotalStorage Productivity Center in the future. MDM consists of software components 
that enable storage administrators to monitor, configure, and manage storage devices and 
subsystems within a SAN environment. MDM also has a function to manage the Copy 
Services functions, called the 

. 

For further information about MDM, see 14.5, “IBM TotalStorage Productivity Center” on 
page 282.

 

There are differences between the ESS CLI and DS CLI. 

The ESS CLI needs two steps to issue Copy Service functions:

1. Register Copy Services task from the Web user interface.

2. Issue the registered task from CLI.

The DS CLI has no need to register a Copy Services task before you issue the CLI. You 
can easily implement and dynamically change your Copy Services operation without the 
GUI. 

For further information about the DS CLI, see Chapter 10, “DS CLI” on page 195.
