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
6.3.3 DS 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.
