In This Chapter

Adaptec Disk Array AdministratorTM is a utility that manages the

storage devices connected to your DuraStor RAID controllers. It is

embedded in the firmware of the controller, and can be used with

any Operating System (OS).

You can use Adaptec Disk Array Administrator to create and

reconfigure arrays, initialize disk drives, manage spares, monitor

the status of your storage devices and more. You can also use it to

access newly-created arrays immediately after creating them.

About This Guide

This User’s Guide describes the features available in Adaptec Disk

Array Administrator and how to use them. It assumes that you are

familiar with the basic functions of your OS.

It also assumes that you are familiar with basic computer hardware

and network administration terminology and tasks, and that you

have a working knowledge of Redundant Array of Independent

Disks (RAID) technology.

Accessing Adaptec Disk Array Administrator

You can access Adaptec Disk Array Administrator using the

RS-232 serial port on the DuraStor 6200S RAID appliance. Use the

port associated with the controller you wish to access. Refer to the

DuraStor Installation and User’s Guide for more information.

You must connect a computer with terminal emulator software,

such as HyperTerminal, to the serial port. You must use a straight-

through serial cable. You cannot use a null modem cable.

Note: If you are using HyperTerminal as your terminal

emulator software, you must be using HyperTerminal

Private Edition (HTPE) 6.3 for the up and down arrow

(↑or ↓) keys to work.

If you are not using HTPE 6.3, you can download it for free

at www.hilgraeve.com/htpe/index.html.

Configure the RS-232 port in your terminal emulator software

using the settings in Table 1-1.

Set the communications parameters for the terminal emulator

software as shown in Table 1-2.
