automatically selected by host type during

host access configuration.

Disk Storage Manager graphical user interface

(GUI) or command-line interface (CLI). The GUI

includes wizard-based tools and a task-based

structure designed to simplify installation, con-

figuration, management, and diagnostic tasks.

Modular Disk Storage Manager enables admin-

istrators to discover storage systems through

either Serial Attached SCSI (SAS) or Ethernet,

troubleshoot using diagnostic utilities, and

manage virtual disks, hot-spare drives, firm-

ware upgrades, and event logs (see Figure 4).

It includes both in-band and out-of-band man-

agement capabilities, along with an optional

event monitoring service (used to send alerts

when a critical problem occurs).

In-band management is available when the

PowerVault MD3000 is connected to the host

server using SAS and Modular Disk Storage

Manager is fully installed, including the host-

based storage agent, multipath drivers, and

management station package. Out-of-band man-

agement is available when client systems can

connect to the PowerVault MD3000 using

Ethernet and the Modular Disk Storage Manager

management station package is installed.

The Modular Disk Storage Manager CLI gives

administrators direct access to a script engine

utility that reads commands and runs script files.

Tasks administrators can perform using the CLI

include the following:

•

Create script command batch files when

installing the same configuration on multi-

ple storage arrays

•

Run script commands on a storage array

directly connected to a host, a storage array
