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 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 to access the DPT setup. The PCI DAC setup screen will appear in approximately one and one half minutes after pressing . 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 - Continue. Step 17: Press - 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 - 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 - OK. Step 25: The "Storage Manager - Local" window is displayed. Step 26: Select each disk drive in turn and format by pressing and then . 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 - Switch view - RAID configuration window. Step 30: Press - Create Array Group. Then OK to continue. Step 31: Select each drive to be included in the array. Press to select the drives. A check mark will be displayed on each of the drives to be included in the array. Step 32: Press - to include the drives in the array. Step 33: Press - to indicate that drive selection is complete. Step 34: Press 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 - (File pull down menu). Step 36: Press - to set the configuration. Then - 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 - (File pull down menu). Step 38: Press - to exit the configuration. Then - OK. Step 39: Press - 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 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 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 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 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 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.
