Determine how you want to configure the shared servers/subsystem SCSI
bus interconnect before you begin setting up (Chapter 1).
Install the host adapter into the server that requires one. Prior to installing
the host adapter, you must remove the resistor packs from the board.
Set up the shared servers/subsystem SCSI bus interconnect configuration that
you selected (Chapter 1).
Designate the existing server as Host A and the new server as Host B to
distinguish between them for software setup procedures that you must
perform on one server or the other (Chapter 2).
Run the Host Adapter Configuration Utility on both servers to set host
adapter SCSI IDs and (Adaptec host adapters only) to deactivate on-board
termination and disable power-on reset. You must set unique SCSI IDs for
the host adapters. Set Host A to SCSI ID 7 and Host B to SCSI ID 6.
Boot Windows NT on each of the servers.
Install host adapter device drivers onto the server into which you installed
the new host adapter. The host adapter requires drivers to operate with your
systems (Chapter 2).
Install the Command Console.
Install the HSZDISK driver on Host A (even though you previously loaded
it) and Host B. The HSZDISK driver are required for the RAID subsystem
to operate with your systems (Chapter 2).
Reboot both servers. You must reboot both servers for the HSZDISK drivers
to take effect.
Verify the HSZDISK drivers installed correctly on both servers. Use the
Event Viewer to locate an event for the HSZDISK in the event log. Clicking
on the HSZDISK event displays an event detail window that indicates
whether the HSZDISK drivers loaded (Chapter 2).
Run Disk Administrator on Host B to reassign C as the disk partition letter
of your system disk, if desired (Chapter 2). The installation of HSZDISK
drivers causes Windows NT to reassign the disk partition letters, particularly
reassigning the letter C from your system disk to the first HSKDISK, Disk 0.
You can use the cluster with the disk partition letters as assigned after the
HSZDISK installation or you can change the drive partition letters yourself.
Download controller firmware, if required.
EK–SMRAF–IG. D01
Getting Started
14. Install Windows NT Service Pack on Host B and on Host A as well, if not
already installed. DIGITAL Cluster software requires Windows NT Service
Packs for certain versions of Windows NT. Refer to the release notes to
determine the supported versions of Windows NT and the specific service
packs required to operate DIGITAL Clusters software with those versions of
Windows NT.
15. Reboot both servers after service pack installation. If you needed to install a
Windows NT Service Pack, you must reboot the servers for the service pack
to take effect. (Chapter 2).
16. Install the Cluster Management Software.
This completes the overview of steps required to configure a StorageWorks
RAID Array for Windows NT Clusters. Go to Chapter 1 to begin the
installation.
Configuring When You have Not Yet Installed a RAID Array
This section lists the major steps and provides a checklist-type roadmap for
setting up a StorageWorks RAID Array for Windows NT Clusters if you've not
yet connected a StorageWorks RAID Array subsystem to a server. See the
specified chapters for detailed procedures.
1.
Determine how you want to configure the shared servers/subsystem SCSI
bus interconnect before you begin setting up (Chapter 1).
2. Install the host adapters into the servers. Prior to installing the host adapters,
you must remove the resistor packs from the boards (Chapter 1).
3. Set up the shared servers/subsystem SCSI bus interconnect configuration that
you selected (Chapter 1).
4. Designate the servers as Host A and Host B to distinguish between them for
software setup procedures that you must perform on one server or the other
(Chapter 2).
5. Run the Host Adapter Configuration Utility on both servers to set host
adapter SCSI IDs and (Adaptec host adapters only) to deactivate on-board
termination and disable power-on reset. You must set unique SCSI IDs for
the host adapters. Set Host A to SCSI ID 7 and Host B to SCSI ID 6 (Chapter
2).
6. Boot Windows NT on each of the servers.
7. Install host adapter device drivers on both servers. The host adapters require
drivers to operate with your systems (Chapter 2).
8. Install the Command Console.
9. Install the HSZDISK driver (on both servers). The HSZDISK driver are
required for the RAID subsystem to operate with your systems (Chapter 2).
10. Reboot both servers. You must reboot both servers for the HSZDISK drivers
to take effect.

Installation Guide – RAID Arrays for Windows NT Clusters
11. Verify that the HSZDISK drivers are installed correctly on both servers. Use
the Event Viewer to locate an event for the HSZDISK in the event log.
Clicking on the HSZDISK event displays an event detail window that
indicates whether the HSZDISK drivers loaded (Chapter 2).
12. Run Disk Administrator on Host A to create partitions, assign drives, and
format and label the RAID array storagesets (Chapter 2).
13. Run Disk Administrator on Host B so that Windows NT can poll the current
device configuration and lock down the partition drive letter assignments.
After Disk Administrator starts and Windows NT has polled the current
device configuration, exit Disk Administrator.
14. Reboot Host B so that Windows NT can view the new device configuration
that you created from Host A.
15. Run Disk Administrator on Host B to verify that it sees the new device
configuration that you created from Host A.
16. Download controller firmware, if required.
17. Install Windows NT Service Pack on both servers, if necessary. DIGITAL
Cluster software requires Windows NT Service Packs for certain versions of
Windows NT. Refer to the DIGITAL Clusters software release notes to
determine the supported versions of Windows NT and the specific service
packs required to operate DIGITAL Clusters software with those versions of
Windows NT.
18. Reboot both servers after service pack installation. If you needed to install a
Windows NT Service Pack, you must reboot the servers for the service pack
to take effect. (Chapter 2).
19. Install the Cluster Management Software.

Determining How to Configure the Shared Servers/Subsystem SCSI
Bus Interconnect
The various components of the cluster (the servers, the RAID array subsystem)
connect through the SCSI bus. Therefore, you must determine where you plan to
locate each of the cluster components on the SCSI bus as the first step in
configuring. You also need to know how you plan to locate the cluster
components on the SCSI bus to properly set termination on the host adapters.
EK−SMRAF−IG. D01

Installation Guide –RAID Arrays for Windows NT Clusters
The major considerations for configuring the shared servers/subsystem SCSI bus
interconnect include:
•
Defining the two ends of the SCSI bus by selecting where you want to
situate the subsystem on the SCSI-bus. You can locate the subsystem:
⇒ In the middle of the SCSI bus (410/HSZ40 or 450/HSZ50 subsystems)
⇒ On an end of the SCSI-bus (all subsystems)
•
Terminating each end of the SCSI bus.
You must terminate a SCSI bus at each end.
Where you locate each of the cluster components on the SCSI bus with
410/HSZ40 or 450/HSZ50 subsystems matters only by your preference or any
physical limitations of the components in your facility. You must locate a
310/HSZ20 subsystem at an end of the SCSI bus.
Figures 1−1 and 1−2 show the SCSI bus interconnect configuration available for
dual controller RAID Array 410/HSZ40 and 450/HSZ50 subsystems. Figures 1−3
and 1−4 show the SCSI bus interconnect configuration available for single
controller RAID Array 410/HSZ40 and 450/HSZ50 subsystems. Figure 1−5
shows the SCSI bus interconnect configuration available for a RAID Array
310/HSZ20 subsystem. View these figures, and decide which configuration you
want to use. Section 1.2, Connecting the Cluster Components through the SCSIbus describes how to connect and terminate the cluster components according to
the configuration you select.
NOTE
Although the diagrams in Figures 1−1 through
1−4 specify the RAID Array 410 subsystem only,
these diagrams apply for HSZ40 and 450/HSZ50
subsystems also.

2.1
Designating Servers as Host A and Host B
You must perform many of the software setup procedures specified in this
chapter twice, once on each server. This chapter specifies which procedures you
need to perform on one, the other, or both servers. This chapter distinguishes
between the two servers by referring to them as Host A and Host B. Therefore,
prior to beginning the software setups, designate one of the servers as Host A and
one as Host B as specified in Sections 2.1.1 for new and 2.1.2 for existing RAID
array configurations.
2.1.1 New RAID Array Configuration
If you are configuring a cluster with a new RAID array subsystem, it does not
matter which server you assign as which host; designate one as Host A and one
as Host B. However, once you begin the software setups, you must consistently
perform the procedures for Host A on the specific server you designated as Host
A and the procedures for Host B on the specific server you designated as Host B.
2.1.2 Existing RAID Array Configuration
If you are configuring with a previously installed RAID Array, designate the
existing or server currently connected to the RAID Array as Host A and the
new server as Host B.
2.2

2.5
Using StorageWorks Command Console with Windows NT Clusters
The StorageWorks Command Console (Command Console) allows you to
configure and manage your RAID Array subsystem in the Windows NT Clusters
environment.
You can configure Command Console to operate on a remote management
station over the network, and/or through a direct serial connection between the
subsystem and a host.
Running Command Console on a remote management station requires Command
Console agent software on each of the cluster servers. The agent software
enables communications between the remote management client and the RAID
Array subsystem. The agent uses the TCP/IP transport to communicate with the
remote management client and a communications LUN storageset to
communicate with the RAID Array subsystem over the SCSI bus.
Typically, you can use any RAID Array storageset as a communications LUN
storageset. However, in the cluster environment you must configure your cluster
failover groups so that each cluster host is primary server for the RAID Array
drive you selected as the communications LUN storageset. This RAID Arraybased drive will act as the communications LUN storageset for the agent on that
particular server. If host failover occurs, remote RAID Array management is
maintained through the other server's communications LUN storageset.
Running Command Console in direct serial mode, requires a serial cable
connection between the management host's COM port and the RAID Array
subsystem.
2.5.1 Selecting a Command Console Set-up
For ongoing configuration and maintenance of your clustered RAID Array
subsystem, set up Command Console using one of the following specified
configurations. In addition, after reading about the various configuration options,
read the sections on Installing Command Console with a New RAID Array and
Installing Command Console with an Existing RAID Array, to determine which
configuration options are most appropriate for your situation.
2.5.1.1 Direct Serial Connection
This option configures Command Console to communicate with the RAID
subsystem through use of a direct serial connection. Connect a serial line
between the COM port or a local Windows 95 or NT PC on which you installed
Command Console and the RAID Array. This is the simplest method of
configuring Command Console. This method does not permit remote
management over the network.
EK−SMRAF−IG. D01
2−9
Installation Guide – RAID Arrays for Windows NT Clusters
2.5.1.3 Direct Serial Connection and Remote Management
This option configures a direct/serial connection in addition to a remote
management station. You must connect a serial line between the COM port of
the cluster or a local Windows 95 or NT PC on which you install Command
Console, and the RAID Array. You must also install Command Console agent
software on each of the cluster servers and the Command Console client software
(GUI) on the remote management station(s). In addition, you must install and
configure the TCP/IP protocol on both servers and on the remote monitoring
station.
This is the preferred option, because it permits RAID Array configuration and
monitoring to be performed locally, even if the network or SCSI channel is not
available, or through use of a remote management station during normal
operation.
2.5.1.4 Installing Command Console with a New RAID Array
If you are installing a new RAID Array and wish to use Command Console with
a remote management station, you still must set up to use the direct/serial mode
initially in order to create at least two storage sets. These two storage sets will
be used as the communications LUN storagesets. The communications LUN
storagesets, along with agent software, will be used to establish a communication
path through the SCSI bus for Command Console remote management.
2.5.1.5 Installing Command Console with an Existing RAID Array
If you have an existing RAID Array subsystem (previously configured) you may
not have to use Command Console in the direct/serial mode. If at least two
storagesets have already been configured on the RAID Array these may be used
as communications LUN storagesets, as long as one can be assigned to a primary
failover group on each server.
See the Command Console Version 1.1 User's Guide for more information about
the Command Console and the Getting Started - StorageWorks RAID Array for
Windows NT Installation Guide for more information about the communications
LUN storageset.

2.6.1 Running Disk Administrator
To run the Disk Administrator, follow these steps:
NOTE
To safeguard critical data, backup your system
using normal backup procedures before altering
device partitions.
The instructions provided here are summary in
nature; refer to your Windows NT documentation
for additional information.
1.
From the Start Menu, choose Programs and Administrative Tools group
for Windows NT 4.0 or the Administrative Tools group for Windows NT
3.51.
2.
Select Administrative Tools.
3.
Select Disk Administrator.
NOTE
The first time you run Disk Administrator after
adding new disks, one or more message
window(s) may appear asking you to confirm
whether you want to have Disk Administrator
provide its “signature” on the new disks. Confirm
doing so (by clicking on Yes) in order to have Disk
Administrator recognize these new disks. For
more information on this subject, refer to your
Windows NT documentation.
Disk Administrator creates a “Bar Chart” display of your disk configuration, as
shown in Figure 2−12. If you are installing a RAID Array for the first time, the
Disk Administrator displays the RAID Array storagesets as raw partitions of free
space, with no drive letter assignments, and no format.
Before proceeding, you should verify the following:
An entry exists in the Disk Administrator display for each of your local disks
and RAID Array logical disks.
•
EK−SMRAF−IG. D01
2−21
Installation Guide – RAID Arrays for Windows NT Clusters
•
If not, recheck your configuration. You may need to verify either the logical
or physical (or both) configuration of your RAID Array.
The capacity shown for each device should match the size of the physical disk
or the RAID Array storageset.
NOTE
Disk Administrator displays the “usable” capacity
of a RAIDset and Mirrorset, not the combined total
of the physical members.
If not, recheck the logical configuration for the RAID Array and its members.
Now, go on to Section 2.6.2 for a previously installed RAID Array, or skip to
Section 2.6.3 for a new RAID Array.
2.6.2 Removing Drive Letter Assignments Temporarily
Installing HSZDISK drivers when you have a previously installed subsystem
causes Windows NT to reassign the drive letters of Host B partitions. Windows
NT inserts all RAID array-based partitions ahead of any local (non-shared bus)
partitions. Windows NT would, for example, reassign drive letter C from your
Host B system disk to the first storageset partition, Disk 0.
Since drive letter reassignments could invalidate your drive mappings, this
section shows you how to remove your drive letter assignments prior to installing
the HSZDISK drivers.
Remove drive letter assignments for all partitions except the BOOT partition.
After you install and verify the HSZDISK installation, you start the Disk
Administrator and reassign the appropriate drive letters.
2−22
EK−SMRAF−IG. D01
Chapter 2. Performing Software Setups for Sharing a StorageWorks RAID Array in a Cluster
To remove drive letter assignments temporarily, follow these steps:

Installation Guide – RAID Arrays for Windows NT Clusters
When you finish removing all of the drive letter assignments, go on to Section
2.6.3 to install the HSZDISK Class Driver onto your hosts. After you install and
verify the HSZDISK Class Driver, you then reassign the appropriate drive letters
to the partitions.
2.6.3 Installing the HSZDISK Class Drivers from the CD-ROM
Install the RAID Array HSZDISK class drivers onto both servers in the cluster.
To install the HSZDISK class drivers, follow these steps:
1.
Install the StorageWorks RAID Array Cluster Utilities and Drivers
Distribution CD-ROM in the CD-ROM drive of Host A.
2.
For Windows NT 4.0 systems, choose “Run” from the Program Manager
File menu. Enter the command shown below substituting your CD-ROM’s
driver letter for the one shown:
3.
Drive_letter:\Drivers\HzInstal\Setup.exe
4.
Repeat Steps 1-3 on the other host.
2.6.4 Rebooting One Server at a Time After Drivers Installation
After installing the device and HSZDISK class drivers on both servers, reboot
Host A. When Host A has completely rebooted, reboot Host B.
NOTE
If HSZDisk is already installed on Node A, you do
not need to reboot it.
You must reboot the servers for the drivers to take effect. Device drivers must
be in effect prior to installing any Windows NT Service Pack, if necessary.

EK−SMRAF−IG. D01
Chapter 2. Performing Software Setups for Sharing a StorageWorks RAID Array in a Cluster
2.6.5 Verifying HSZDISK Drivers Installed
Verify that the HSZDISK class driver properly installed on each of the servers.
To verify the HSZDISK installation, follow these steps:
1.
Open the Event Viewer from the Administrative Tools group.
2.
Locate an information icon in the Event Viewer window with HSZDISK for
the Source, similar to the event shown in Figure 2−17.
Figure 2−17 Event Viewer Log
3.
Double click on the HSZDISK entry and an entry detail screen appears
similar to the screen shown in Figure 2−18.
The message in the detail screen indicates whether the HSZDISK class driver
was successfully installed.
EK−SMRAF−IG. D01
2−27
Installation Guide – RAID Arrays for Windows NT Clusters
Figure 2−18 Event Detail
If the HSZDISK class driver was successfully installed on Host A, repeat steps
1−4 of this section to verify that it was successfully installed on Host B.
If the HSZDISK class driver did not load successfully, verify that no errors
appear in the Event Viewer window for the DECKZPSX driver for Alpha
systems or the AIC78XX driver for Prioris systems.
If errors appear for either of these drivers in the Event Viewer window, a
connectivity problem may exist on the shared SCSI-bus. HSZDISK will not load
while these problems exist. Check for the following:
•
Correct termination
•
Faulty cables or connections
•
Proper adapter seating in the system backplane
•
SCSI ID conflicts
Also, review Chapter 1 for installation procedures.
After resolving any of these problems, reload the HSZDISK driver.
If the HSZDISK driver still fails to reload, call field service (as specified on the
warranty card) or your Sales Representative.
Now, go on to Section 2.6.6 for directions on how to prepare storagesets for use
in a new RAID Array subsystem. Otherwise, skip to Section 2.6.7 for instructions
on how to reassign drive letters to partitions of a previously installed RAID
Array.

Chapter 2. Performing Software Setups for Sharing a StorageWorks RAID Array in a Cluster
2.6.6 Preparing Storagesets for Use in a New RAID Array Subsystem
NOTE
Storagesets should be created using SWCC
before proceeding with this step.
When installing a cluster with a new RAID Array subsystem, you need to
prepare the storagesets for use.
Follow these steps for creating partitions, assigning drives, formatting and
labeling the storagesets in your RAID Array subsystem:
1.
2.
Run Disk Administrator as specified in Section 2.6.1.
Create partitions as follows:
For each disk shown, select the partition area that you wish to create.
• Click on the Partition pull-down menu. From the Partition pull-down
menu, choose Create (see Figure 2–19).
•
The Create window opens (see Figure 2–20).
NOTE
A disk cannot be accessed unless it contains at
least one valid partition formerly created under
Disk Administrator.
Figure 2–19 Partition Pull-Down Menu
EK−SMRAF−IG. D01
2−29
Installation Guide – RAID Arrays for Windows NT Clusters
Figure 2–20 Create Primary Partition Window
In the window, enter the partition size you want, then click on OK. (Depending
upon the partition size you choose, a message window may appear asking you to
confirm your selection.)
3.
Continue to create new partitions until all disks have been partitioned.
4.
Optional: Make disk logical names permanent.
The process of creating partitions assigns a logical name (the letter “C,”
“D,” etc.) to each partition. These letter assignments, under Windows NT,
will normally “float.” That is, they are subject to changing (after reboot), if
the disk configuration changes.
You may, however, make these assignments “permanent.” (For more
information on this subject, you should consult your Windows NT
documentation.) If you wish to make the letter assignments “permanent,”
access the Tools pull-down menu. From the choices given, select Drive
Letter then choose To Assign. This process must be repeated for each
partition (drive letter) that you wish to make “permanent.”
5.
When you have created all your partitions, go back to the Partition pull
down menu and click on Commit Changes Now (see Figure 2–19).
A message window will then appear asking you to confirm that you wish to
commit these changes.
2−30
EK−SMRAF−IG. D01
Chapter 2. Performing Software Setups for Sharing a StorageWorks RAID Array in a Cluster
After confirming that you wish to commit the changes, a new message
screen should appear advising that the “Commit Changes” action was
successful.
NOTE
A message window will appear following this step
asking you if you wish to save a copy of the
configuration to a floppy. You may do so at this
time, as prompted by the screen display.
6.
While still running Disk Administrator, click on the Tools pull-down menu,
then select Format (see Figure 2–21). The Format menu choices (see
Figure 2–22) allow you to choose either FAT or NTFS. You must select
NTFS options to use the disks as clustered disks.
NOTE
Windows NT Clusters requires the NTFS format
for clustered disks.
You may also choose the Quick Format option. Select OK to begin the
format process. For further information regarding these options, refer to your
Windows NT documentation.
A message window appears advising you when the formatting is complete.
Figure 2–21 Tools Pull-Down Choices
EK−SMRAF−IG. D01
2−31
Installation Guide – RAID Arrays for Windows NT Clusters
Figure 2–22 Format Menu
7.
Continue to format each new partition until all partitions have been
formatted.
8.
When all partitions have been formatted, close Disk Administrator. At this
point, the configuration has been completed on Host A, and is recognized by
Windows NT.
2.6.6.1 Running Disk Administrator on Host B
After preparing the storagesets for use on Host A, run Disk Administrator on
Host B, so that Windows NT can view the current device configuration. Once
you start Disk Administrator on Host B and Windows NT has polled the current
device configuration, exit the Disk Administrator on Host B.
2.6.6.2 Rebooting Host B
Reboot Host B so that Windows NT will recognize the new device
configuration.
This completes the procedures for preparing disks for use with a new RAID
Array subsystem.

after you install the HSZDISK class drivers, follow these steps:
1. Start Disk Administrator as described in Section 2.6.1. The disk
administrator displays all the existing partitions, similar to the window
shown in Figure 2−23. The only partitions with drive letters are the boot
partition and any non-disk devices, such as a CD−ROM drive.

Using the Command Console
as a Remote Application
Using the Command Console as a Remote Application for networked RAID management
entails the selection and installation of the Command Console on both the PC and each
clustered host.
To use the Command Console as a remote application, for networked RAID
management, you must select a PC for your management station, install the
Command Console on the PC and install the Command Console Agents on each
of the clustered hosts. For more information about networked remote Command
Console installations, see the Command Console V1.1 User's Guide.
The major steps for using the Command Console as a remote application include
the following:
4.1
•
Installing Windows NT TCP/IP Network Transport
•
Selecting a network PC for your management station and installing the client
software
•
Installing the Agents on your cluster servers
Installing Windows NT TCP/IP Transport
The SWCC Command Console uses the TCP/IP transport for communications in
a networked remote client environment. Both hosts in the cluster must be
configured for simple TCP/IP services. If either of the hosts have not been
configured for simple TCP/IP services, see the Windows NT Server System Guide
to configure them.

4.2
Installing the Command Console on a Networked, Remote Client
Select Windows 95 or Windows NT PC clients for management stations and
install the client software. See the Command Console Version 1.1 User's Guide
for more information.
Command Console installs from the StorageWorks RAID Array Controller
Software distribution CD-ROM using a standard Windows installation routine.
To install Command Console:
1.
Place the CD in the CD-ROM drive.
2.
Open the File menu in the Program Manager for Windows NT 3.51 or click
on the Start Button for Windows NT 4.0.
3.
Select the RUN option.
4.
In the text box, type drive_letter:\SWCC\CLIENT\INSTALL and
click OK.
5.
Follow the instructions in the setup program to complete the installation.
4. 3 Installing the Agent
The Command Console Agent is a companion application to the Command
Console Client graphical user interface (GUI) program. The Command Console
Agent runs on your cluster host systems.
You must install the Command Console Agent on each of your hosts.
Install Agents only after installing the Cluster Management software and
defining failover groups. Each of the clustered servers must be configured as the
primary server for at least one of the RAID Array storagesets. This allows the
Command Console to communicate with the RAID Array through either host
SCSI channel in the event of a server failurea failover situation.
You install the agents as a service on each server. The agents enable
communication between the RAID Array and the Command Console on a remote
client system. The agents communicate with the RAID Array through the SCSI
bus and the communications LUN storageset. They communicate with the
remote clients through the Windows NT TCP/IP network transport.
Installing the Command Console Agent requires the following major steps:
