CONTROLLER TERMINOLOGY
In reading the accompanying RAID Array 200 documentation, please
note the following terminology associations:
This Refers to Or
RAID Array 210 EISA KZESC-xA, KZESC-xB SWXCR-EA, SWXCR-EB
controller
RAID Array 230 PCI KZPSC-xA, KZPSC-xB SWXCR-PA, SWXCR-PB
controller
The RAID Array 200 Controller documentation and software uses
SWXCR for generic references to controllers.
NUMBER OF SWXCR CONTROLLERS SUPPORTED
All of our drivers and utilities are setup to support four
controllers (any combination of EISA or PCI) with the exception
of SCO UNIX. The total number of EISA/PCI SWXCR controllers
supported under SCO UNIX is two (in any combination).
CONFIGURATION WITH SHARED INTERRUPTS
We recommend using edge triggered interrupts for the SWXCR
controller.However, if you choose to use level interrupts,
limit the number of boards sharing the same interrupt to
avoid performance problems.
TERMINATION
The SWXCR-Px (KZPSC-xx) must be at the end of the SCSI bus in an
8 bit environment for proper termination of the unused SCSI
signals. You do not need to make any changes on the shelf end of
the SCSI connection, simply follow the appropriate documentation.
When using Fault Management the terminators used must support
Fault Management. The SWXCR controllers are supplied with
termination that supports Fault Management. Check with your
system supplier to be sure that system/device termination
supports Fault Management, otherwise the Fault Management option
must be DISABLED on the controller. If there is termination
attached to any channel of the SWXCR that does not support Fault
Management the results are unpredictable with Fault Management is
not DISABLED.
REVISION MATRIX
The following table cross references the hardware board revision
levels for the RAID Array 200 family of controllers with the
release date and revision level of the software accompanying the
board. The FW and BIOS columns refer to firmware and BIOS
revision levels; the other columns refer to the version numbers
of the respective distribution diskettes for the release of all
Intel based utilities (KIT), the Standalone Configuration Utility
(RCU), Windows NT (NT), NetWare (NW) and SCO UNIX (SCO)
utilities.

WRITE BACK CACHE
If you plan to use write back cache on the SWXCR-Px controllers
you should order the Battery backup option for the controller to
avoid data loss under circumstances where the controller is
unable to complete a write operation to disk (for example, power
failure). Also we recommend that the disk drives attached to the
controller have their write cache disabled; contact your drive
vendor for more information.

option will spin the drive up and allow a format under the
rebuild option.
NOVELL NETWARE NOTES
RAID Array 200 Software V3.0 for Intel NetWare 3.1x/4.x
USE OF INTERRUPT 15 IN NETWARE
SWXCR controllers in the Novell NetWare operating environment
must not be configured to use IRQ 15.
PASSTHRU DEVICE SUPPORT ON THE SWXCR CONTROLLER UNDER NETWARE
Use of passthru devices (for example, CD-ROM and tape drives) is
possible by loading the included ASPI drivers for NetWare
(SWXCRASP.DSK for v3.1x and SWX40ASP.DSK for v4.x). Please note
that only one ASPI driver from any vendor may be loaded under
NetWare at any one time. Some vendors (for example, Adaptec) do
not allow optional loading of their ASPI module. If you choose
to use drivers of this type you will not be able to use the SWXCR
ASPI modules to provide passthru support. This would not prevent
use of the SWXCR to controller disk devices.
When using passthru devices on the SWXCR, the following
restrictions apply:
Each controller may be configured with a maximum of 7
passthru devices.
Each passthru device must occupy a unique SCSI ID (for
example., ID 0 to ID 6) within the controller.
NETWARE DOCUMENTATION
Chapters 2 and 3 of the RAID Array 200 Online Management Utility
for NetWare 3.1x and 4.x indicate by example two methods for
loading the NetWare utilities. The method in Chapter 2 describes
copying the utilities to the NetWare SYS: volume. This method
enables loading the utilities from the system console without
specification of a path component. The alternative method
described in Chapter 3 is to copy the utility files to a MS-DOS
directory. This procedure avoids the necessity of logging into
the server from a client workstation to complete the
installation. You may choose which ever method is most
convenient for your needs. Note that the disk driver modules
(SWXCRDRV.DSK for v3.x and SWX40NET.DSK for v4.x) must be
installed into a MS-DOS directory in order to remain accessible
to the server at boot time.

SCO UNIX Notes
RAID Array 200 Software V2.0 for Intel SCO UNIX
SCO UNIX DISTRIBUTION DISKETTE FORMAT
The distribution diskette for SCO UNIX is a UNIX formatted floppy
for BTLD installations. It is unreadable under MS-DOS.
CONFIGURATION OF DEVICES ON THE SWXCR CONTROLLER
Configuration of disk and passthru devices is performed using the
standard SCO UNIX command, mkdev. Disk devices are configured
using mkdev hd syntax. Likewise, tape and CD-ROM drives use
mkdev tape and mkdev cdrom syntax. In use, the mkdev command
will prompt for a SCSI ID and logical unit number (LUN) when
creating each device. All disk devices should be configured with
LUN = 0. All passthru devices should be defined with LUN = 1.
Each of the controller痴 8 possible disk drives must be assigned
a unique SCSI Id (for example, ID 0 to ID 7).
Each controller may be configured with a maximum of 7 passthru
devices. Each passthru device must occupy a unique SCSI ID (for
example, ID 0 to ID 6) within the controller.
SCO UNIX SWXCR NAMING CONVENTIONS
Name Description
swxcr Driver package name
xcr Driver name
/dev/rreX00 Controller node name
where X is 0 for the first SWXCR controller
where X is 1 for the second SWXCR controller
Use SCO standard device names For Hard disk/Tape/CD-ROM
node names
PARTITION RESTRICTIONS UNDER SCO UNIX
SCO UNIX imposes a file system size limit of 2 GB for each of 7
partitions per logical drive. This yields a total usable logical
RAID drive size of 14 GB (7x2 GB). Please note this when
configuring Logical RAID Drives with the Standalone Utility.
SCO UNIX DOCUMENTATION
In the Main Menu of the swxcrtk utility, options 3, 4, 5, and A
contain a Note referring the user to the SWXCR manual chapter
entitled "Terminology." Please refer to table 2-2 in the
StorageWorks RAID Array 200 Online Management Utility for SCO
UNIX Users Guide in these instances.
UPGRADES SHOULD BE PERFORMED IN SINGLE-USER MODE
To upgrade an existing SCO UNIX installation with the RAID Array
200 Online Management Utility, bring the system to a single-user
mode prior to beginning the upgrade. This will ensure that the
swxcrmon process is properly updated.
FRESH SCO UNIX INSTALLATIONS ON THE SWXCR CONTROLLER
When performing a fresh installation of SCO UNIX in conjunction
with the RAID Array 200 Online Management Utility, the following
devices are automatically configured to facilitate the SCO
installation:
First Hard Disk: @SCSI ID 0 on the first SWXCR controller,
LUN 1
Tape @ SCSI ID 2 on the first SWXCR controller, LUN 0
STOPPING AND STARTING THE SWXCRMON PROCESS
The swxcrmon process is configured to start automatically when
installed. If you do not want the swxcrmon process to
automatically start at system startup, you can relocate the
script file xcr which is located in the directory /etc/idrc.d.
Move the xcr script file to another directory for safekeeping;
the swxcrmon process will then not start automatically.
Restoring the file to the /etc/idrc.d directory will resume the
automatic invocation of the swxcrmon process on system startup.
You can start the swxcrmon process anytime by manually running
the command swxcrmon from a shell prompt.
DEFAULT LOCATION OF THE SWXCRMON LOG FILE
The default location for the swxcrmon log file is
/usr/adm/swxcrmon.log. You can change this to another file
specification by giving the desired file specification as a
command line argument when manually invoking swxcrmon or by
editing the /etc/idrc.d/xcr file. In the latter case, add the
new log file specification after each occurrence of the swxcrmon
command.
SWXCRMON MESSAGE OUTPUT
When swxcrmon is invoked as a foreground process, its message
output is sent to its log file and the terminal window from which
is was started. In the case of invoking swxcrmon as a daemon
process (for example, with the -d switch), the message output will
go to the log file and the console.

WINDOWS NT NOTES
RAID Array 200 Software V2.1 for Intel Windows NT
WINDOWS NT ON THE DIGITAL PRIORIS HX 590 FAMILY OF SERVERS
When a PCI SWXCR controller is used on the Digital Prioris HX 590
server, it must be installed in the primary PCI bus slots (slots
1, 2, and 3). Windows NT version 3.51 is the minimum required
revision level of the NT operating system on this platform.
INSTALLATION OF NT ON SWXCR BOOT PARTITIONS WITH MULTIPLE LOGICAL
DRIVES
There is a limitation in the Windows NT installation mechanism
which results in a failure to successfully complete an
installation to a SWXCR boot device when more than one logical
drive is defined on that device. The failure will occur when the
system attempts to boot after the first three floppy disks are
loaded. This limitation can be overcome by one of two methods.
Method one is to simply install an MS-DOS partition on the first
logical drive before beginning the Windows NT installation.
Method two is to postpone creation of the second and subsequent
logical drives until after Windows NT is completely installed on
the first logical drive.
PARTITION RESTRICTIONS UNDER WINDOWS NT
The Windows NT boot partition size cannot exceed 2024 MB in size.
Please note that any FAT partition created which is over 2 GB in
size will be inaccessible to MS-DOS. Please see Microsoft痴
Windows NT documentation for further details.
PASSTHRU DEVICE SUPPORT ON THE SWXCR CONTROLLER
Windows NT v3.1 does not support passthru devices such as tape
drives and CD-ROMs, for example. Windows NT 3.5 and later support
any number of passthru devices without restrictions.
SYSTEM SERVICES VERSION OF THE SWXCRMON UTILITY
There is provided an alternative version of the SWXCRMON utility
that operates as system service under Windows NT. This version
will start automatically whenever the NT system is booted.
Otherwise, the system service monitor is identical in
functionality to the standard version provided through the SETUP
routine. You may use each version separately or together. We
welcome any comments you have regarding this utility; please see
the address shown under the feedback section of the General
release notes.
The files for the system service monitor utility are located on
the NT release disk under the directory \serv_mon. The
instructions for installation and removal of the utility are
contained in the file SWXCRSRV.REL located in that directory.
UTILITY VERSION NUMBERS
The revision levels for the Windows NT utilities are:
SWXCRMON v1.35
SWXCRMGR v1.26
SWXCR DRIVER ON THE WINDOWS NT V3.5 CD-ROM
The miniport driver for the SWXCR controller is included on the
Windows NT distribution media for Windows NT 3.5. The version of the
driver included on the v3.5 CD has the following problems:
a) Level interrupts can not be used for any SWXCR controller as this
will cause the system to hang.
b) There is a bug while using tape devices to backup data on any
Logical RAID Drive while there is activity to the same or other
Logical RAID Drives which will cause the system to panic and crash.
The above problems have been fixed and a new version of the SWXCR driver
is included on this floppy in the root directory. To load and use this new
driver simply copy the file DAC960NT.sys from the floppy to the
Winnt35\system32\drivers directory of your system. This can only be done
after installing the operating system and the controller using the driver on
the distribution CD.
USE OF DISK ADMINISTRATOR IN WINDOWS NT 3.5
There is a problem in the Windows NT 3.5 operating system that may be
seen while using the SWXCR Monitor or SWXCR Manager in conjuction with
the Disk Administrator utility. Using the above utilities together may
cause the system to crash. Contact Microsoft support and say you want the
fix for bug #25912, which is a new SCSIPORT.SYS file for Windows NT 3.5,
to correct this problem.
HELP FILE IN THE SWXCRMGR
The 'Help file...' option under the Help menu of the SWXCR Manager has
not been enabled. Windows NT default help will be displayed.
