AST RESEARCH, INC.        TECHNICAL BULLETIN # 1585          09/17/96 
 
 
 
TITLE:  Installing SCO OpenServer 5 Manhattan P
 
 
SUMMARY 
 
   The Manhattan P may not recognize the DPT PM3224A controller.
   
   This issue affects the following systems: 501533, 501534, 501651, 
   501660, 501701, 501702, 501703, and 501754.    


ISSUE 
 
   When installing SCO OpenServer 5 on a Manhattan P system using 
   the CD-ROM on the NCR SCSI controller, and the hard disks on the 
   DPT SCSI controller, the system may not recognize the DPT PM3224A
   controller.    

 
BACKGROUND 
 
   N/A    

 
ACTION 
 
   Before beginning the installation, please read TB # 1022A which 
   is available on any of AST's On-Line! services. This TB explains 
   how to reconfigure the NCR controller for use with SCO Unix.
   
   1. Obtain the latest NCR SCSI drivers for OpenServer 5 
   ------------------------------------------------------- 
   Download RAWRITE3.COM and SCO30600.DD from 
   ftp.symbios.com/pub/symchips/scsi/drivers/Unix_Drivers/SCO_Unix, 
   or from the Symbios BBS in the USA: (719) 573-3562. Build the 
   diskette by typing "rawrite3" at a DOS prompt, then follow the 
   instructions on the screen. 
   
   2. Obtain the DPT SCSI drivers for SCO Unix
   -------------------------------------------
   Boot with DOS, start storage Manager (v1EB) and build the SCO 
   Unix driver diskette. Build the RAID if a RAID is wanted. 
   Alternatively, download SCO5BTLD.ZIP from 
   ftp.dpt.com/pub/techsup/unix/sco or from the DPT BBS in the USA: 
   (407) 831-6432 and build the diskette. 
   
   3. Move the CD-ROM to the DPT controller 
   ---------------------------------------
   The CD-ROM drive has to be connected to the DPT SCSI bus during 
   initial system installation. The DPT SCSI cable may not have 
   enough connectors to allow this. If this is the case, the NCR 
   SCSI cable will have to be used temporarily in its place. Turn 
   the system OFF. Disconnect the SCSI cable connecting the NCR SCSI 
   controller to the CD-ROM. Disconnect the SCSI cable connecting 
   the primary DPT SCSI connector to the upper row of hard disks on 
   the Manhattan backplane. Replace this cable with the SCSI cable 
   that was removed from the NCR controller. Take out the CD-ROM and 
   remove its termination resistor packs. Save the resistors. Plug 
   the second to the last SCSI connector of the SCSI cable coming 
   from DPT channel 0 into the CD-ROM, and the last connector into 
   the upper hard drive backplane. This order is important, as the 
   SCSI bus termination is done on the Manhattan backplane.
   
   4. Install SCO Unix
   -------------------
   Insert the SCO CD into the CD-ROM drive, then boot with the SCO 
   install disk. At the Boot prompt, enter
   
    "defbootstr ahslink=dptr5"
   
   This will install SCO Unix on the hard drives (s) attached to the 
   DPT. During the install, SCO will ask for the DPT driver 
   diskette. Make sure to create an emergency boot diskette during 
   the install (just in case).
   When the install has finished, shut down the system and turn it 
   OFF. Take out the DPT driver diskette.
   
   5. Move the CD-ROM back to the NCR controller 
   -------------------------------------------- 
   Unplug the CD-ROM from the SCSI cable, and unplug the SCSI cable 
   from DPT channel 0 and from the hard drive backplane. Put back 
   the original SCSI cable linking DPT channel 0 to the SCSI 
   backplane. Put back the termination resistors on the CD-ROM. Put 
   back the CD-ROM and its power connector into its original slot. 
   Put back the SCSI cable linking the NCR controller to the CD-ROM.
   
   6. Install the NCR SCSI drivers
   -------------------------------
   Turn the system ON, boot, and log on as root.
   Make a backup of the working kernel (just in case). Enter
   
    "copy /unix /unix.dpt"
   
   (The backup kernel can be accessed at the Boot: prompt by typing 
   its name "unix.dpt".) 
   Insert the NCR driver diskette.
   Pop up a Unix prompt. 
   Mount the NCR driver diskette: 
   Type "mount /dev/fd0 /mnt"
   Make the root of the NCR driver diskette your current directory. 
   Type "cd /mnt"
   Install the NCR BTLD driver from the diskette. 
   Type "btldinstall /mnt" 
   Choose the slha driver, which is the NCR driver for OpenServer 5. 
   When the driver install has finished, relink the kernel.
   Type "cd /"
   Type "/etc/conf/cf.d/link_unix"
   Once the kernel relink has finished, shut down the system. Take 
   out the NCR driver diskette.
   
   7. Configure the CD-ROM on the NCR controller 
   -------------------------------------------- 
   Boot the system back up and login as root. 
   Pop up a unix prompt.
   Type "mkdev cdrom"
   Delete the CD-ROM from the DPT (the dptr5 device driver), then 
   create it again on the NCR (choosing the slha device driver). 
   When "q"uitting out of mkdev, the system will prompt you to 
   relink the kernel and its environment. Follow the procedure. Shut 
   the system down and bring it back up again.
