MC communicates with each server in the storage units via the Ethernet network. Therefore, the MC is a key component to configure and manage the DS6000.

The client must provide a computer to use as the MC. If they want, they can order a computer from IBM as the MC. An additional MC can be provided for redundancy.

For further information about the Management Console, see Chapter 8, “Configuration planning” on page 125.

6.3.2 DS Storage Manager Web-based interface

DS Storage Manager is a Web-based management interface. It is used for managing the logical configurations and invoking the Copy Services functions. The DS Storage Manager has an online mode and an offline mode; only the online mode is supported for Copy Services.

The client will install the DS Storage Manager on the Management Console. You can also install it in other computers that you prepare. When you manage Copy Services with DS Storage Manager in your computers, DS Storage Manager issues its commands to the Management Console via the Ethernet network.

The DS Storage Manager can be used for almost all functions for Copy Services. The following functions cannot be issued from the DS Storage Manager in the current implementation:

￿Consistency Group operation (FlashCopy and PPRC)

￿Inband commands over Remote Mirror link

6.3.3DS Command-Line Interface (CLI)

The IBM TotalStorage DS Command-Line Interface (CLI) helps enable open systems hosts to invoke and manage FlashCopy and Metro and Global Mirror functions through batch processes and scripts. The CLI provides a full-function command set that allows you to check your storage 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 CLI:

￿Check and verify your storage configuration.

￿Check the current Copy Services configuration that is used by the server enclosure.

￿Create new logical volumes and Copy Services configuration settings.

￿Modify or delete logical volumes and Copy Services configuration settings.
