IBM DS6000 Series manual DS open application programming interface API

Tip: What is changed from the ESS CLI?

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.

6.3.4 DS open application programming interface (API)

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 MDM Replication Manager.

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