Overview NetWare 5.0
This section provides information about the following:
• Installation procedures and the functionality of the Mylex Disk Array
Controller drivers for Novell NetWare 5.0. The software is provided on
the appropriate Software Kit distribution diskette.
• Installation, verification, and startup of the Global Array Manager
Server software and utilities for Novell NetWare 5.0. The software is
provided on the appropriate GAM Server distribution diskettes.
Mylex Disk Array Controller Driver Files for NetWare
All hardware installation, system configuration, and disk array controller
configuration must be properly completed before proceeding with the
NetWare driver installation. These basic installation procedures follow the
Novell Installation manual, with only the few minor differences that are
described in this section, Netware 5.0.
The subdirectory \NW on the NT/NW drivers diskette contains the following:
MDAC.HAM: The driver to support Mylex Disk Array Controllers
with NetWare 5.0.
MDAC.DDI: NetWare installation file for MDAC.HAM.
Tape and CD-ROM Support
Tape drive support is available to the Mylex Disk Array Controller under
NetWare by means of the NWASPI driver module that provides ASPI
compatibility. Most NetWare applications that communicate through ASPI
on the server will work with the controller.
Similar to tape drive support, CD-ROM is also supported by the controller
for use under NetWare. The NWASPI driver module must first be loaded to
provide ASPI support to the CD-ROM application running on the server. An
NWASPI driver and a CD-ROM driver will also have to be loaded. These are
included with the Novell NetWare releases.

14 eXtremeRAID DAC1164P Quick Installation Guide
Installing Peripherals Under NetWare 5.0
Non-disk peripheral devices, such as tape or CD-ROM drives, can be
installed on any channel of the controller. Each non-disk device will require
a unique SCSI ID, different from any other non-disk device connected to the
controller regardless of the channel.
1. The NetWare 5.0 NWASPI must be loaded. For example:
:load nwaspi.cdm
☛Note
NWASPI.CDM must be loaded during startup,
otherwise you will need to copy it from the Novell
distribution CD-ROM.
2. After the nwaspi driver is installed, other appropriate drivers should be
loaded before trying to access the non-disk devices. For example, to
use NetWare's Sbackup utility, do the following:
:load mdac.ham
:load nwaspi
:load tsa500
:load tapedai
:scan for new devices
:load sbackup
Except for the mdac.ham driver, .NLM files are supplied by Novell.
Refer to the Novell documentation for instructions on running Sbackup.
3. Load the following drivers (.NLM) to use a CD-ROM under NetWare
5.0 (the NLM, CD-ROM, is supplied by Novell):
:load mdac.ham
:load scsicd.cdm (in the startup file)
:load cdrom
:cd mount [volume name]
After the CD-ROM is mounted, the volume on the CD-ROM can be
mapped from any workstation and accessed.
