Supported Operating Systems for the Raid Array 3000
You have purchased support for the Windows NT operating system version 4.0 with Service Pack
3, 4, 5 and Windows NT operating system version 3.51 with Service Pack 5 on an Alpha PCI
platform. The supported host adapter is the SWXA3-BD differential PCI host adapter for Alpha
systems.
Supported Configurations
Your RAID Array 3000 contains a single dual-ported controller. This allows support for eight
SCSI logical units (LUNs) per port, or a total of 16 LUNs per controller. A second controller (DS-
HSZ22-AA) can be added for redundancy and performance. The minimum version of controller
firmware for both controllers is D11U. The controller firmware contained on the CD-ROM is
D11V (in the \firmware directory) that is part of this kit. If the controller is running an earlier
revision of Firmware (D10I, D11O, or D11U), you will need to upgrade the Firmware prior to
making the RA3000 operational.
You may create a Windows NT boot partition on the RAID Array 3000 storage subsystem. The
Windows NT boot partition can be at most 4 GB in size. Ensure that the host adapter is configured
to default parameters (BIOS enable, wide negotiation, >1 GB translation).
Table 1 lists the minimum system requirements needed for the RA3000 operating software,
Version 1.2.

Required Driver Revisions
HSZDISK
HSZDISK.SYS is a class driver required for all RAID Array 3000 Windows NT configurations. It
is designed to enhance the error recovery features built into your Compaq RAID system, and to
provide more robust operation than the native Windows NT SCSI disk class driver.
HSZDISK.SYS only affects DIGITAL RAID devices. Other SCSI disk drives in your system
continue to be serviced by the native SCSIDISK.SYS class driver. The drivers are included in the
CD–ROM labeled RA3000 Solution SW V1.2 for Windows NT (Alpha).
Version 4.11 of the HSZDISK.SYS class driver supports Microsoft Windows NT Server 4.0 and
Windows NT Server 4.0 Enterprise Edition with Microsoft Cluster Server (MSCS).
Version 2.72 supports Microsoft NT Server 3.51. The setup procedure automatically installs the
correct version for you.
SCSI Host Adapter Description
The host adapters qualified for use with your StorageWorks RAID Array 3000 for Windows NT is
the SWXA3–BD Ultra-Wide Differential SCSI Host Adapter. Table 2 lists the exact specifications
of the qualified host adapter.

On-line Documentation
Your RAID Array 3000 reference manuals are part of the RAID Array 3000 V1.2 for Windows
NT –Alpha CD-ROM. They can be viewed and printed using Adobe Acrobat Reader when
installed on an Alpha-based Windows platform. A copy of the reader is included in the CD-ROM
for your convenience.
RAID Array 3000 Operating Constraints
Controller
Always Operate Your RAID Array 3000 with the UPS-to-Pedestal Serial Cable Connected
The UPS serial cable must be connected at all times. This cable is used to communicate a power
failure to the controller. When the controller senses a power failure, it automatically saves your
data to disk. The purpose of the UPS is to keep your system running until the controller
accomplishes its task of saving cache data to disk.
Wait Until the Disk Drive Fault Indicator Clears Before Using the Disk
Disk Drive fault LED clearing takes approximately two minutes. Do not attempt to use a disk drive
until its fault indicator turn off.

Changing the RAID Array Configuration
NOTE
To safeguard critical data, backup your system using normal
backup procedures before altering device partitions. Do not
alter partitions that contain important data.
When making changes to an existing RAID Array configuration, any existing disk partitions to be
changed (or removed) must first be deleted using the Windows NT Disk Administrator. After they
have been deleted, you may use the StorageWorks RAID Array 3000 Storage Subsystem
Command Console Client to create new virtual disks. (Refer to the Command Console User’s
Guide and on-line help to make the changes).

Release Notes
AA–RACVC–TE 5
Removing Disk Partitions
1. From Disk Administrator, click the partition you wish to delete.
2. Access the Partition menu and choose Delete.
3. Continue selecting and deleting the partitions until you have deleted all the partitions you wish. When
finished, click on Commit Changes Now. You may now reconfigure the StorageWorks RAID Array
3000 Storage Subsystem Array using Command Console Client.
4. Reboot your system so Windows NT will recognize the changes.
Shutdown Procedure
You must issue shutdown from SWCC. Do not turn off the system power before shutdown is
issued. (When shutdown is issued from SWCC, the controller first flushes the cache to the disk
drive, then stops blinking).
•If a controller requires a rebind, the SCSI bus must be quiesced before performing this
operation. All I/O must be stopped before replacing the failed controller.
•Reconnecting the SWCC client may be necessary if any of the following conditions occur:
1. Controller failover.
2. Lost connection to the subsystem.
3. SWCC does not reflect the correct state of the controllers after a FAILBACK (rebind).
4. Deletion of virtual disks and/or RAIDsets.
StorageWorks Command Console (SWCC)
This version of SWCC software is for use with the StorageWorks HSZ22 controllers only. This
product CANNOT be used for configuring any other StorageWorks controllers. The following is a
list of known issues and limitations of the SWCC Client software.
•Initial configuration – The SWCC Client requires one serial connection for the controller
in the RA3000 subsystem for initial configuration. The initial configuration of a dual
controller system requires a PC with two serial ports. You must connect each controller to
a different communications port on the PC on which the SWCC Client software is running.
Check the Getting Started manual, AA–RACZB–TE, for details. If the PC is equipped
with a single serial port, refer to the Single Controller Option Guide, DS-HSZ22-AA.
•Firmware download – If you must upgrade the controller firmware, you must connect via
the SCSI bus or network. If the boot device is located on the RA3000, refer to the Read
Me File on the CD-ROM which explains how to download firmware using a serial
connection.
•Save/Restore Utility – Your RA3000 SWCC configuration application includes a
“Save/Restore” utility. If the restore operation is unsuccessful, use the HSZ22
UltraFix.exeDOS utility included in the /SWCC directory on the CD-ROM to repair
the “Restore” feature. The utility is executed from a DOSSHELL in the format HSZ22
UltraFix.exe‘x:’, where ‘x’ is a virtual disk on your RA3000 storage system. This
will correct the problem and allow you to successfully restore your RAID configuration.
