Introduction Assumptions
The AcceleRAID 150, AcceleRAID 200 and the AcceleRAID 250 are very versatile Ultra2 SCSI, LVD RAID controllers. There are literally thousands of possible hardware configurations. In order to keep this Quick Installation Guide down to a manageable size, the following assumptions are being made: A RAID 0, 1, or 5 installation is being installed. The user is familiar with Windows NT or Novell NetWare. The user is familiar with disk drive and RAID terminology.

Types of Installations

There are two types of installations: Standard Installation SCSI Interrupt Steering Logic (SISL) Installation

Standard Installation

In a standard installation, the AcceleRAID 150 or the AcceleRAID 250 functions as a single-channel, standard PCI to Ultra2 SCSI, LVD RAID controller. In a standard installation, the AcceleRAID 150 or 250 can be installed into any system board with an available PCI (2.1 compliant) slot.
SCSI Interrupt Steering Logic (SISL) Installation
In a SISL installation, the AcceleRAID 200 adds RAID functionality to a system board that has one or more embedded SCSI channels. The AcceleRAID 150 or 250 adds an Ultra2 SCSI, LVD RAID channel as well as RAID functionality to a system board that has one or more embedded SCSI channels. For a SISL implementation, the AcceleRAID controllers must be plugged into a special, pre-wired PCI slot in a system board that is specially designed for this type of installation. Check with the manufacturer of your system board to find out if it has embedded SCSI channels that can be controlled by a PCI to SCSI RAID controller with SCSI Interrupt Steering Logic (a requirement for the AcceleRAID 200).
Performing a Standard Installation

(AcceleRAID 150 and AcceleRAID 250 only)

Caution

If an operating system or existing data resides on SCSI disk drives already installed on the system, a full backup should be performed on these drives prior to this installation. 1. Be sure power is turned off and the system is not plugged into an electrical outlet.
To avoid electrical shock, do not attempt to perform this hardware installation with power on. Disconnect the system from the electrical wall outlet. 2. If JP10 on the AcceleRAID 150 or 250 is installed, remove it, as shown in Figure 1 and in Figure 2.

4. Set the SCSI ID on each internal drive to a unique address between 0 and 15, but do not use address 7, as it is reserved for the controller. See the documentation that comes with your drives for instructions on how to do this.
If internal and external drives are used, be sure that no drive addresses are duplicated. External SCSI cabinets usually automatically assign drive addresses according to where in the cabinet the drives are located. 5. Be sure termination is disabled on all drives connected to the controller. See the documentation that comes with your drives for instructions on how to do this. 6. Be sure that termination power is enabled on all drives connected to the controller. See the documentation that comes with your drives for instructions on how to do this. 7. Connect a wide, high-density, 68-pin SCSI ribbon cable to the internal SCSI connector on the AcceleRAID 150 or 250 and connect the other cable connectors to any internal SCSI drives as required. See Figure 5. 8. Connect an active terminator to the end of the SCSI ribbon cable at the end farthest from the controller. See Figure 5.

When an AcceleRAID 150 or 250 is plugged into the SISL PCI slot, the channel on the controller automatically assumes the address of Channel 0. The addresses of the channels on the system board are pushed out by one.

4. For each channel, set the SCSI ID on each internal drive to a unique address between 0 and 15, but do not use address 7, as it is reserved for the controller. See the documentation that comes with your drives for instructions on how to do this.
If internal and external drives are used, be sure that no drive addresses on a given channel are duplicated. External SCSI cabinets usually automatically assign drive addresses according to where in the cabinet the drives are located. 5. Be sure termination is disabled on all disk drives connected to the controller or connected to the system board. See the documentation that comes with your drives for instructions on how to do this. 6. Be sure that termination power is enabled on all disk drives connected to the controller or connected to the system board. See the documentation that comes with your drives for instructions on how to do this. 7. Connect a wide, 68-pin, high-density SCSI ribbon cable to the internal SCSI connector on the AcceleRAID 150 or 250 and connect the other cable connectors to any internal SCSI drives as required. See Figure 10.
Figure 10. Connecting Internal and External Drives
8. Connect an active terminator to the end of the SCSI ribbon cable at the end farthest from the controller. See Figure 10. 9. Connect a wide, round, 68-pin VHDCI cable to the external SCSI connector on the AcceleRAID 250 and connect the other end of the cable to an external drive cabinet as required. See Figure 10. External drive cabinets usually have termination built into the end of the SCSI bus. 10. Connect a wide, 68-pin, high-density SCSI ribbon cable to the SCSI connector on the system board and connect the other cable connectors to any internal SCSI drives as required.
If a narrow SCSI connector is available on the system board, this should be used for non-disk SCSI peripherals, such as tape or CDROM drives which will not be a part of a RAID array.

Using RAID EzAssist

RAID EzAssist, the on-board BIOS Configuration Utility is used to build several types of RAID configurations. Since this is a Quick Installation Guide, only the Automatic Configuration option will be described here.
A first time installation is being assumed. The following limitations apply to Automatic Configuration: Only one array will be configured using the Automatic Configuration option. All drives being controlled by the AcceleRAID board can be different sizes, but will all be formatted to the size of the smallest disk controlled by the AcceleRAID board. A maximum of 7 drives can be configured into an array using Automatic Configuration. Any additional drives will become hot spares. The drives with the largest capacity (if mixed drive sizes are used) will be the drives selected to become hot spares.
If you want to do anything other than an automatic configuration, refer to the RAID EzAssist Configuration Utility User Reference Guide. To perform a RAID configuration with the Automatic Configuration option using RAID EzAssist, do the following: 1. First power on any disk enclosures connected to the AcceleRAID controller, and then power on the computer. The AcceleRAID controller is furnished with the BIOS enabled by default. 2. Watch the messages on the screen for the following prompt to be displayed:
Press <ALT-M> for BIOS options
Wait approximately 5 seconds. Do not press any keys at this time.
If the BIOS has been disabled on the controller, You will need to press AltM to enable it (See your controllers Installation Guide for details). 3. Watch the messages on the screen for the following prompt to be displayed:
Press <ALT-R> for RAID Configuration options
4. Press AltR to get into RAID EzAssist (the configuration utility).
For more detailed information on how to run the RAID EzAssist, refer to the RAID EzAssist Configuration Utility User Reference Guide (P/N 775029), which is included on the distribution CDROM. The utility will scan all available drive channels for SCSI devices. Upon completion of the scan, the following will occur under the following conditions: a. More than one controller:

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.
Mylex Disk Array Controller Driver for NetWare 5.0
Installing the Mylex Disk Array Controller as the Primary NetWare 5.0 Controller
If the Mylex Disk Array Controller will be the primary (bootable) controller, you must install the controller driver at the time of NetWare 5.0 installation.
Installing NetWare 5.0 Drivers
NetWare version 5.0 is available on CD-ROM. Drivers provided in the \DOS subdirectory of the Software Kit Distribution diskette (packaged with the Mylex Disk Array Controller and Disk Array Controller Configuration Utility manual) are required to install NetWare 5.0 from a CD-ROM drive connected to a Mylex Disk Array Controller. The procedure below assumes that the CD-ROM drivers are available. 1. Boot the system from a newly created DOS boot drive, and then create (or edit) the CONFIG.SYS and AUTOEXEC.BAT files to include the drivers required for accessing the CD-ROM as a logical drive under DOS. The following example assigns the CD-ROM as drive D: under MS-DOS 6.00 or above. CONFIG.SYS contains the statements:

The device name is that of the specific CD-ROM drive (e.g., MSCD001). 2. Boot the system with the new CONFIG.SYS and AUTOEXEC.BAT, and make sure the NetWare CD-ROM files are accessible under DOS. 3. Follow the standard NetWare 5.0 upgrade or installation procedure, as described in the NetWare 5.0 documentation. While the files are being copied, a message will appear stating matching drivers to hardware devices.
4. Watch for the status screen that displays the drivers found for storage adapters: Select Modify Select Storage Adapters Delete the MDAC.HAM line entries 5. Press the Insert key two times in order to add new drivers from another source.

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

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, cdrom, is supplied by Novell):
