320La Disk Maintenance Utility Software Notes 3
Introduction
This document provides information for installing and using the
Express5800/320La ft Server Disk Maintenance Utility (DMU). Using the DMU
you can display the relationship between the physical locations of disk drives in
your system and their logical designations. This utility can also identify the
physical to logical mapping of hard disk drives located in 320La ft Disk
Expansion Units connected to your server. Using the Disk maintenance Utility
you can:
!
Identify and display the physical positions of all disks in you server and
DEUs (if applicable).
!
Display the status of disks. This feature allows you to quickly identify
the physical location of a defective disk in your system.
!
View the mapping between physical disks and logical disks in your
system.
Installing the Disk Maintenance Utility

name it “DMUVIEW.” To create the DMUVIEW folder:
Right-click on “Start” and left-click on “Explore” to open Windows
Explorer.
Select a location on your hard drive for the DMUVIEW folder.
Left-click on “File – New – Folder. Name the folder “DMUVIEW.”
2. Insert the DMUVIEW diskette labeled “Physical to Logical Drive Mapping”
into the diskette drive.
3. Using Windows Explorer, copy the DMUVIEW.exe application from the
diskette to the DMUVIEW folder on your hard drive.
4. For easy access to the DMUVIEW utility, it is recommended that you create
a DMUVIEW shortcut icon on your desktop. To create a desktop shortcut:
Select the DMUVIEW.exe located in the DMUVIEW folder on your

Running the Disk Maintenance Utility (DMU)
1. Double-click on the DMUVIEW shortcut located on the Windows Desktop.
The DMU starts and the FT Disk Maintenance Utility screen displays.
Slot Position displays the physical slot locations for hard disk drives in your
320La ft server, whether your server is a tower model or a rack-mount model.
As an example, facing the front of a tower model server, the physical drive slot
locations are numbered 1 through 6, left to right.
Note:
The
Slot Position screen shows only the physical
numbering of disk drive slots, and does not display actual
disk drives installed in these slots. Use this information along
with information in the right pane to determine the physical
location of logical drives in your server.
Slot-1 through Slot-6 shown in this display refers to the physical slot locations
shown under Slot Position. Referring to the above screen, the rectangular green
boxes at Slot-1 and Slot-4 indicate that a disk drive is located in each of these
slots. Within the green box is displayed the logical SCSI disk number and the
current status of the drive. The logical disk IDs are Disk 1 and Disk 0. The
formatted capacity of each disk drive is also shown.
