			  INSTALLATION OF DPT PCI RAID CONFIGURATIONS


PROBLEM

During installation of the DPT PCI Disk Array Controller (DAC) in the 
Manhattan P and V Servers, the DAC may not properly configure the drives as a 
RAID configuration.  Problems may also be encountered when mounting Novell 
Netware 4.X volumes after installation of the DAC.


CAUSE

The documentation which accompanies the PCI DAC does not make clear the 
importance of following a specific set of steps during the installation of the 
product.  Any deviation from the installation procedure may result in 
complications after the installation. 

Follow the installation procedure below for precise instructions.

Note: The current DPT Storage Manager diskette part numbers are: 911709-034 
and 911709-035.  For additional information on the DPT PM3224 PCI Storage 
Manager Utilities, see Software Bulletin 0207 on AST's BBS.

Part I - Configuring the PCI DAC for RAID

Step 1: Ensure that all SCSI IDs are correctly jumpered either on the drives 
themselves or on the SCSI backplane if one is installed.  Make sure to check 
that the SCSI ID cables fit tightly and are installed over the correct pins.  
At all times during the installation, all drives should be seen by the 
configuration utilities. If any drive is not seen by the utility, check to 
make sure that the SCSI ID is set correctly and that no SCSI IDs are in 
conflict. (For additional information on the Manhattan P And Incorrect SCSI 
ID Assignments, see TB1078 located on AST's BBS.)

Note: When two drives in the system have the same SCSI ID, the system may 
crash, or drives may intermittently drop on and off-line.  Also note that if a 
SCSI ID jumper is not installed, the default setting is ID 0.  If all drives 
are not recognized, try setting any installed device with ID 0 to another ID 
and re-test the system.

Step 2: Ensure that termination is installed at the ends of the SCSI bus 
sub-system.  Termination is enabled by default on the PCI DAC.  It is 
recommended that all drives have terminators removed, using the terminators on 
the SCSI backplane for termination.  If a single channel is being used for all 
devices, the CD-ROM should be the last SCSI device on the chain, and 
termination should be enabled on the CD-ROM.

Step 4: Boot the system and when prompted press <F2> to access System Setup.

Step 5: Ensure that the video's 640 x 480 refresh rate is set to "60Hz 
Non-interlaced" for standard VGA and SVGA monitors.

Step 6: Boot the system and when prompted press <Ctrl+D> to access the DPT 
setup.  The PCI DAC setup screen will appear in approximately one and one 
half minutes after pressing <Ctrl-D>.

Step 7: Check the settings indicated in the setup program.  The following are 
the recommended settings:

HBA I/O address:     AUTO
HBA SCSI ID:         7
PCI Parity:          Enabled
SCSI Termination:    Enabled
SCSI Cmd Queuing:    Enabled
SCSI TERMPOWER:      Enabled
PCI Xfers/Burst:     AUTO
SCSI Xfer Rate:      10MHz
Extended PCI REQ:    Disabled
Ext Cable Detection: OFF 10MHz

Step 8: Boot to a DOS floppy disk and load a mouse driver.

Step 9: Insert the Storage Manager utility/configuration disk.

Step 10: Clear all of the drives by typing DPTMGR   /ZAP

Note: This command clears the area on the drives used by the DPT to save RAID 
configuration information.

Step 11: Once the "ZAP" has completed, turn the system power OFF and then back 
ON again.

Step 12: Boot the DOS disk.

Step 13: Insert the Storage Manager utility/configuration disk.

Step 14: Run INSTALL.BAT

Step 15: The screen will blank for about 2 minutes while loading the Storage 
Manager utility/configuration program.

Step 16: Press <Alt+C> - Continue.

Step 17: Press <Alt+C> - Continue.

Step 18: View each device in turn.  Make sure the same make and model hard 
disk drives have the same firmware version and number of blocks.  If the 
firmware versions on identical make and model drives are different, upgrade 
all the drives with a revision of firmware that is recommended for SCSI drives 
used in a hardware RAID environment (or AST qualified firmware revisions for 
AST drives).  If the number of blocks are different, check the number of 
blocks after the drives have been formatted.

Step 19: View the HBA settings:
Model: DPT PM3224A/9X
IRQ: 11 level
Firmware: 7A0
Address: FCF0
Cache:  4MB 
Attached Modules SX4000/1  Raid ready
1: 4mb ECC SIMM 
SCSI Bus Width:  8bit 
Type: single ended 
Transfer: 10
SCSI ID: 7
SCSI buses: 2

Step 20: Press <Alt+C> - Continue.

Step 21: Select the OS required.

Note: Steps for installation of Novell Netware follow.  To install Novell 
Netware, select Netware at this step. 

Step 22: The steps will vary depending upon the chosen operating system.  
Generally, the Storage Manager utility will either create a setup or driver 
diskette for the chosen operating system, or will display information 
pertinent to the particular operating system selected.

Step 23: When the operation is complete, Storage Manager will issue the 
following message: "Initial System Installation is now complete."

Step 24: Press <Alt+O> - OK.

Step 25: The "Storage Manager - Local"  window is displayed.

Step 26: Select each disk drive in turn and format by pressing <Alt+F> and 
then <Alt+Y>.

Step 27: A blue flag indicates that each drive is formatting.

Step 28: Wait for all drives to finish formatting before continuing.

Step 29: Press <Alt+V> - Switch view - RAID configuration window.

Step 30: Press <Alt+C> - Create Array Group. Then <Alt+O> OK to continue.

Step 31: Select each drive to be included in the array. Press <Shift+Spacebar> 
to select the drives. A check mark will be displayed on each of the drives to 
be included in the array.

Step 32: Press <Alt+I> - to include the drives in the array.

Step 33: Press <Alt+D> - to indicate that drive selection is complete.

Step 34: Press <Alt+O> and read the screen carefully.

Note: The logical drive and the array drive will display a black flag to 
indicate that the logical drive's configuration is different from the 
configuration stored on the PCI DAC.  Only when the logical drive is "built" 
and you have exited Storage Manager will the configuration be saved to the PCI 
DAC.

Step 35: Press <Alt+F> - (File pull down menu).

Step 36: Press <Alt+S> - to set the configuration. Then <Alt+O> - OK.

Note: The logical array drive displays blue flag indicating it is "building" 
the array. The individual drive will show a white flag.  Wait until the 
logical drive has finished building - no flags on the drives.

Step 37: Press <Alt +F> - (File pull down menu).

Step 38: Press <Alt +X> - to exit the configuration. Then <Alt+O> - OK.

Step 39: Press <Alt+Y> - to save the configuration.

Step 40: The system will reboot.  Wait until the system finishes rebooting 
before turning the system OFF and ON again.  The system is now ready for the 
OS to be installed.


Part II - Additional information regarding Novell Netware 4.X  

When installing Novell Netware, follow the documentation included with Netware.  
Ensure that the latest DPT Server Disk Driver is used (PM14NW40.DSK).  
The driver is available from AST's electronic BBS and forums, as well as from 
DPT, as part of the latest storage manager utilities, part numbers 911709-034 
and -035 (file names 709034.EXE and 709035-EXE).

What follows is a sample step by step approach to installation of Novell 
Netware 4.X.

Step 1: Boot DOS from a diskette and prepare the hard disks for installation 
of Novell Netware.  Refer to Novell's documentation for specific information.  
Generally, a DOS partition should be created on the hard disk of approximately 
20MB and set active.  Leave the remainder of the drive un-partitioned.  
The DOS partition should then be formatted and DOS should be installed.  

Step 2: SCSI drivers must be loaded in the CONFIG.SYS file and the 
AUTOEXEC.BAT file in order to access the CD-ROM during the Novell Netware 4.X 
installation.  Sample configuration files are:

CONFIG.SYS
Device=doscam.sys
Device=cdrom.sys  /d:phil_001
Files=12 
Buffers=15

AUTOEXEC.BAT
Path=C:\DOS
MSCDEX   /d:phil_001

Step 3: Reboot the system to load the SCSI drivers.

Step 4: Type 
	D: 
to access CD-ROM

Step 5: Type 
	CD:\NETWARE\ENGLISH

Step 6: Type 
	INSTALL

Step 7: Select "Install new netware v4.x"

Step 8: Select "Retain current disk partitions".

Step 9: Choose a name for the Server.

Step 10: Choose an Internal IPX network address.

Step 11: Select the installation directory (Default is C:\SERVER.40).

Step 12: Select Country codes information <F10> to continue.

Step 13: Select Filename Format (Default is DOS format).

Step 14: Select "No Startup Commands".

Step 15: Make a selection at "Do you want AUTOEXEC.BAT to load SERVER.EXE?"

Step 16: System scans for available drivers.

Step 17: Press <INS> to select an unlisted driver.

Step 18: Put diskette into drive A which contains PM14NW40.DSK; 
"Netware v4.xx DPT PCI SCSI driver"

Step 19: Install switches to Server Console and loads drivers

Step 20: Select "Continue with installation".

Step 21: Create Netware disk partition.

Step 22: Choose "Automatically".

Step 23: Select <F10> to save.

Step 24: Choose "YES" to confirm save.

Step 25: Insert Netware License diskette as requested.

Step 26: Install system and public files.

Step 27: Choose <Alt - F10> to exit the installation program.

Step 28: Bring down the Server by typing 
	DOWN

Step 29: Exit to DOS by typing 
	EXIT

Step 30: Remove SCSI device drivers from CONFIG.SYS and AUTOEXEC.BAT to avoid 
conflicts with Netware SCSI drivers.
	
Step 31: Reset the system by pressing the <RESET> button.

Step 32: Type 
	CD\SERVER.40.

Step 33: Type 
	SERVER 
As Novell Netware loads, the PM14NW40.DSK drivers will load and display status 
messages.  After successfully loading, Volume SYS will be mounted.

Step 34: Type Load install to start the Novell Netware installation program.  
Continue with the installation by adding Network drivers and creating the 
AUTOEXEC.NCF and STARTUP.NCF files.

Step 35: When complete, DOWN the Server, EXIT to DOS, and reboot.  The Server 
should come up without errors.
