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.

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.
