    Hi,
    
    	We have been experiencing problems of file corrupted in
    	4*4GB disks configured as RAID 5 with Mylex controller.
    
    	Attached please find the problems that I posted in the
    	other conference which I have been advised to look for
    	help in this conference.
    
    	Can someone please help and shed some light on this?
    
    	If you need more information, please let me know with
    	the instruction as I don't know much about Mylex.
    
    	Thanks in advance.
    
    	Regards,

    Hi,
    
    	I need help on Mylex RAID-5 drive running on WIN-NT 4.0 SP1 .
    
     	What happens is that the drive F: with 4x4GB disks configured
    	as RAID-5 has been running into 'file corruption' conditions
    	from time to time. It begins to happen when there are *many*
    	files in the disk.
    
    	(This happened before we upgraded to NT 4.0! So NT 4.0 does
    	 not seem to know/fix the problem. )
    
    	Is there a limit on number of files in a drive in NT? If so,
    	what is the limit and what limits it? Can it be resolved ?
    
    	FYI:	All other drives (C,D,E) with 3*2GB are also configured
    		as RAID-5 too and they are running fine. No problem at
    		all.
    
    	So, what happens to the RAID-5 drive F: ?
    
    	Can someone please shed some lights on this?
    
    	Thanks and regards,
    
    /Jimmy

    Hi, Chet,
    
    It is a Prioris Intel HX 5133 DP currently running with WNT 4.0 SP1.
    
    I am not familiar with the firmware and bios, which were came with
    the box. Regarding the 4 gig disk firmware and drives, I don't know
    neither.
    
    I'll have to check it out tomorrow. By the way, as I am new to it,
    can tell me where I can find this info. in the system?
    
    Thanks and regards,

                              README.TXT
            For PRIORIS HX Server Startup/Utility Diskette

This README.TXT is intended for the Prioris HX Server user.  Its
purpose is to provide additional information and corrections to
the user documentation.

DIGITAL BULLETIN BOARD SERVICE:

        Technical information is available 24 hours a day on the
        Digital bulletin board service (BBS).  For access to the
        Digital BBS, dial 508-496-8800 (U.S.).

IMPORTANT INFORMATION:

        WARNING:  Removing the side panels activates the Power Switch
        Interlock (contact switches) and will turn off power to your
        server.  Refer to the Prioris HX User's Guide or Systems and
        Options Configuration Guide for more information.


CONNECTING YOUR MONITOR:

Color monitors may default to monochrome if you don't connect and
turn on your monitor before you power-on your server.


GETTING STARTED

Requirements:

1. Getting Started is designed to run when the Prioris HX
   server is booted from the Startup/Utility diskette
   or when the Getting Started CD is run on a system that is
   running either Windows 3.1 or Windows for Workgroups 3.11.

2. Getting Started will not run with Windows NT, OS/2,
   NetWare or UNIX environments.

3. Getting Started requires a mouse.

4. Getting Started requires SVGA, 256 color environment.
   In VGA or 16 color environments the appearance of the user
   interface is not optimum.

5. Getting Started requires a VESA- compliant video adapter
   (such as the Prioris HX on-board video adapter).
   Other video adapters may prevent Getting Started
   from launching Windows on the CD-ROM with the
   startup diskette.


Accessing the Getting Started Program:

A language and video selection screen appears before you can
view the Getting Started program.  Follow the instructions on
the screen to select the language and video controller that you
want to use.  Your language selection will automatically update the
country and keyboard settings.


Getting Started Notices:

Several Windows WinHelp features are not fully operational when
Getting Started is booted from the startup diskette and runs
Windows on the CD-ROM. These functions ARE fully operational
when Getting Started is run on Windows or Windows for Workgroup
installed on a system's hard drive.  (See the the Prioris HX Server
User's Guide section on Accessing the CD-ROM from a Server or
Workstation.)

These are the Windows WinHelp functions that may produce
error messages:

        ALL OF THESE ERROR MESSAGES MAY BE SAFELY IGNORED

  File/Print Topic selection displays an error message beginning:
    "No Printer Selected. Use Print Setup".
  File/Print Setup selection displays an error message beginning:
    "No Default Printer. Use Control Panel ...".
  Edit/Annotate selection displays an error message beginning:
    "Annotations Damaged. Please exit WinHelp ..."
  Bookmark selection displays an error message beginning:
    "Bookmarks are Damaged. Please exit WinHelp ..."


RAID CONTROLLER:

Booting a Prioris HX server with the RAID controller
installed the following error messages may appear:

        SWXCR FIRMWARE = VERSION 1.99
        SWXCR MEMORY   = 4 MB

                INSTALLATION ABORTED

        PRESS ANY KEY TO CONTINUE

For the purpose of launching the Getting Started program, 
THIS MESSAGE MAY BE SAFELY IGNORED. However, to resolve the RAID
installation problem reference the users manual for the RAID controller.
Follow the instructions on the screen to continue.



NETWARE CONFIGURATION INFORMATION

The StorageWorks RAID Array 200 Subsystem Family Installation
and Configuration Guide (Order Number: EK-SWRA2-IG. A01)
contains a configuration error for NetWare installations.

The following setting should not be used for configuring
the RAID controller interrupt level 15 (reference page 2-11):

    15 Level    15 Edge   (For NetWare only, do not use
                           interrupt 15)




USING ADAPTEC 2940 AND 2940W SCSI ADAPTERS:

Version 1.1 the Adaptec 7800 Manager Set (diskettes)
and BIOS version 1.16 on the 2940 and 2940W are required
for both primary and secondary PCI slots to work with
these adapters.


CORRECTIONS TO THE QUICK SETUP GUIDE:

Step 4 should read:

Connect the monitor power cord to the back of the monitor
(if necessary), and then into a wall outlet or to the
corresponding connector at the back of the server.

Step 6 refers to the Operator Control Panel (OCP) located
at the front of the server.  Push the OCP (LCD) button to
turn the back-lighting on or off.


CORRECTIONS TO THE PRIORIS HX SERVER USER'S GUIDE:

In Chapter 3, the list of files in the UPGRADE directory
should include:

        MINIDOS.SYS
        PHLASH.EXE
        DEVTBLS.DAT
        PHLASH.INI
        PRIORIS.ROM
        MAKEBOOT.EXE
        MAKECRD.EXE

In Chapter 3, "Accessing the CD-ROM", the 2 lines following
item 4 should read:

        If you want to install Getting Started as an icon
        in Windows, select the SETUP button in the country
        selection box.

In Chapter 4, SCSI DRIVE IDs should read:

        SCSI ID Settings:

SYSTEM AND OPTIONS CONFIGURATION GUIDE

The following list contains additional configuration guidelines for the
PRIORIS HX server system.

CPUs
 ----
Do not mix different frequency CPU chips in a dual processor system.
If you have a 5133 CPU card, the J4 jumper should be installed for
the 2/1 clock setting.

Memory
 ------
Do not mix standard parity SIMMs with ECC SIMMs.
Remember that the 590 and 590DP have a maximum DRAM capacity
of 512MB of standard parity SIMMs and 256MB of ECC SIMMs.

Expansion Slots
 ---------------
There are 6 EISA slots available for EISA expansion modules or
adapters and 6 PCI slots available for PCI expansion modules or
adapters.

Storage Space or Slots
 ----------------------
The enclosure can accommodate two 5.25-inch, 1.6-inch height
SCSI devices above the hot swap bays. These spaces can also be
used as one space for a DLT tape backup drive if the system chassis
is modified. There are seven hot swap bays maximum in each system.

Disk Drives
 -----------
There are a number of SCSI hard disk drives available for your servers. They 
come alone or in storage building blocks (SBBs), and either narrow (8-bit)
or wide (16-bit). If you are building a RAID solution try to use drives with
similar formatted capacity and rotational speed. This ensures that you get
the maximum performance from your RAID controller. If you are installing 4GB 
hard disk drives in the system you MUST add a second fan.

Tape Drives
 -----------
If you are adding a DLT series drive to the two 5.25-inch bays
the two metal tabs in the drive bay must be removed.  Contact Digital
Service.

CDROM Drives
 ------------
If you are going to swap out the existing 2X drive with a 4X or simply
are adding a 4X CDROM drive, you have to install the 4X drive in one
of the 5.25-inch bays. The slot for the existing 2X CDROM is a 1-inch
height slot.

Expansion Boxes
 ---------------
BA3xx series expansion boxes connect to the system at the rear of the
system either at a SCSI adapter or at a bulkhead connector.

Other Storage
 -------------
Any other external storage device that will be in a BA3xx expansion
box will connect to the system at the rear of the system either at a
SCSI adapter or at a bulkhead connector.

    Thanks for that, but everything is not there.  Is the system able
    to be brought down?  If so, then you can get the firmware/bios level
    for the controller.  Also I suspect it's a pre-Rev E controller.
    Any firmware with 3.xx is Rev E. and 2.xx is Rev b c or d.
    Depending on the rev, you should go to our web site at 
    
    http://akin40.ako.dec.com/~FTP/Library/OptionsDrivers/STORAGE/SCSI/CTRL/
    PCI/MYLEX/1-05-kit/
    
    if the firmware and bios are not correct. Current is 1.29 bios and 2.39
    firmware.  The kit also includes the latest NT driver for the Mylex.

    Hi, Chet,
    
      Thanks for the information and your pointer to the kit.
    
      Today I have got the kits. However, we have found trouble
      of which one is for upgrade and how . So, finally we have
      it done with the utility Dac960fl.exe in Config.exe kit
      and found a driver file missing, which you mentioned version
      2.39
    
      So, we went to www.mylex.com home page and downloaded the
      file. We then ran the utility Dac960fl.exe with the file
      and got the firmware upgraded to 1.29 and 2.39 .
    
      Above are what we have done. Is that it all?
    
      Since this upgrade is new to me and it does not have the
      detail instructions how it is done. So, I hope I have it
      done right and not missing anything else.
    
      Can you please let me know if you see anything I did wrong
      or missed above?
    
      Thanks again.
    
      Regards,
