Clustering Tips for Microsoft Windows Advanced Server, Limited Edition on Compaq ProLiant DL590/64 Server 3
Introduction to Clustering in Windows
Advanced Server, Limited Edition
The Windows Advanced Server operating system offers cluster functionality improvements over
previous Windows versions. Cluster services are no longer provided as an add-on component of
the operating system. Instead, cluster services are installed as part of the base operating system
installation. A cluster can consist of two to four server nodes. Compaq supports a fibre channel
interconnect for cluster storage. New features offered are listed in Table 1.
Table 1: New features of Microsoft Advanced Server, Limited Edition Cluster Services
Feature Description
64-bit support The Limited Edition of the operating system offers support for the Itanium 64
processor architecture.
Improved Terminal Server installation Terminal Server (also known as Terminal Services in application server
mode) is no longer blocked on servers in a cluster. In Windows2000, the
installation of Terminal Server was blocked if the server was a member of a
cluster.
Improved print driver installations In Windows 2000, each printer driver had to be manually installed on every
node of the cluster. This improved feature installs a printer driver on a virtual
cluster and propagates it to all nodes of the cluster.
Simplified cluster installation wizard This feature provides a new Cluster Configuration wizard that simplifies the
process of installing and configuring the cluster.
Improved Generic Script resource The cluster scripting feature simplifies the process ofclustering applications.
It provides a run-time environment that takes care of complex issues. It also
allows for easy creation of new resource types. Features of this new "generic
script" resource type include the following:
•Monitoring of cluster resources and instrumentation for
applications and services
•Simplifying the implementation new resource types.
•Simplifying scriptable application instrumentation by making the
applications cluster-aware
•Allows a run-time hosting environment
•Existing COM automation servers may be reused
4-node cluster support The Limited Edition operating system supports from two to four cluster
nodes.
Cluster Server Extension This feature provides an extension of the DeviceIOControl call that allows
applications to determine whether a disk is a cluster disk. This call is meant
for applications and services that intend to write to the disk.
Central administration for creating and
adding nodes to a cluster The administrator can use the remote console to configure all servers that form a cluster.
Feasibility analysis during the cluster
setup process During cluster setup, the installation wizard will provide an analysis of the system to ensure the system is correctly set up and the installation is
performed properly.
COM+ 1.x Enhancement: Configure
applications as Windows NT Services This enhancement of COM+ 1.x allows the ability to configure a COM+ server application as a Windows service and implement the Windows service
as a COM+ server application. This provides control over when the COM+
application starts. Marking the application to run as a Windows service
means that the component’s Dynamic Link Library (DLL) is loaded into
memory when the system boots.
When the COM+ application is configured as a Windows service, a Generic
Service cluster resource can be configured for the application. Adding the
COM+ application to a cluster makes the application highly available.

Hardware and Software Configuration Tips
For tips on setting up the ProLiant DL590/64 servers, see the white paper, Deployment of
Windows Advanced Server on Compaq ProLiant DL590/64 Servers. This white paper may be
found at the following link:
http://www.compaq.com/support/techpubs/whitepapers/158m-0801a-wwen.html
For more information on the Compaq StorageWorks MA8000 system see the following link:
http://www.compaq.com/products/storageworks/MA8kEMA12k/index.html.
To configure the cluster with the Compaq StorageWorks MA8000 storage subsystem follow the
guidelines in the Compaq ProLiant Cluster HA/F500 Administrator Guide. Use the basic
configuration with switches. The guide may be found at the following link:
ftp://ftp.compaq.com/pub/supportinformation/techpubs/installation_guides/355220-002.pdf
The fiber channel host bus adapter will require the Compaq 64-bit SCSI miniport driver,
CPQKGPSA.SYS, Version 6-4.52a8 or later. Unlike the HA/F500 cluster, the Windows
Advanced Server, Limited Edition cluster will not use any fibre channel filter driver.
Storage Configuration Tips
Shared Storage Drives must be NTFS
The shared storage volumes in a cluster must be configured as Basic, Master Boot Record
(MBR), NTFS volumes. Dynamic drives and Globally Unique Identifier (GUID) Partition Table
(GPT) drives are not supported in a cluster. The local drives and other drives that are not cluster
resources do not have this restriction.
Drive Letter Assignment
Before adding or removing hardware from a cluster, make sure the drive letter assigned to the
Windows Advanced Server, Limited Edition system partition (typically C or D) is fixed. The
drive letter assignment must remain constant because references to this drive letter are recorded in
the registry, and your cluster is affected by these references.
Consistent Drive Letters for Each Cluster Node
It is also necessary for drive letters on the cluster shared storage device to remain constant and for
the drive letter assignments to be the same on each cluster node. In addition, drive letters for the
cluster shared storage device must not conflict with any local drive letters.
Use Mount Points to Access More Than 23 Devices
If you assign drive letters to the cluster shared storage devices, Windows Advanced Server,
Limited Edition limits the total number of such devices to 23. Mount points are not subject to this
limit. You can use mount points to access more than 23 cluster shared storage devices in your
cluster. Mount points must fail over together with their “host” drive, therefore they both must
reside in the same resource group. The “host” drives must also have a dependency on their mount
points.

Installing Cluster Services
Since the cluster services are installed as part of the operating system, the user must simply
configure the cluster service by setting up a cluster profile. Before installing a cluster verify the
shared volumes are MBR, Basic volumes, not GPT or Dynamic.
Adding the First Node
To add the first node, follow these procedures:
Note: You must be an administrator to create a cluster.
1. Log on to a server you wish to be the first member in the cluster.

6. Enter the computer name of the first node to be added to the cluster. Click Next.
The wizard will analyze the system configuration to determine if a cluster is feasible. If there
are issues that arise during the analysis, the user may need to cancel the installation and
troubleshoot. Once the analysis is complete and no issues arise, click Next to continue.
7. Enter an IP address for the new cluster. Click Next.
8. Enter a user name and password for the Cluster Service account. The user name must have
Domain Admin rights. Click Next.
9. On the next window, verify the cluster configuration. The user may use the Back button to
make changes if necessary. The Quorum drive may be changed by clicking the Quorum
button and selecting the desired drive. Click Next. The cluster will now be created on the
node.

Removing Cluster Services
Windows Advanced Server, Limited Edition does not offer the ability to remove the cluster
services from a node that is part of an existing cluster. The following procedures will effectively
remove the cluster services from a node in an existing cluster.
To remove the cluster services from a node, follow these procedures:
1. Open a Command Prompt.
2. Enter the following command:
cluster node /force
Note: This command will forcibly remove any cluster-related services from the server node.
3. Repeat steps 1-2 on each node in which the cluster services must be removed.

Known Issues
The following is a list of issues of the Microsoft Windows Advanced Server, Limited Edition
clusters on Compaq ProLiant DL590/64 servers. The information is current as of the writing of
this document. This list is not comprehensive. For more information review the operating system
and server release notes.
Compaq Foundation Agent Does Not Start in a Cluster
In a cluster, the Compaq Foundation agent will not start if it is set to retrieve “Clustering
information” from the Compaq Management Agent applet in the Control Panel. This setting will
limit Management functionality of the cluster from Compaq Insight Manager and Compaq Insight
Manager XE.
Solution:
To resolve this issue, open the Compaq Management Agent applet in the Control Panel. Remove
the “Clustering information” agent from the list of “Active Agents” to the list of “Inactive
Agents”. Restart the Foundation agent. Compaq is working on a permanent solution to this issue.
FTDisk Reports Errors While Reading Disk Structures
Following moves of physical drive resources in the cluster (for example, move ownership of
Node 1 resources to Node 3), the Windows fault tolerant driver (FTDisk) reports a failure reading
the disk structures to the System Event log (event 31) of the receiving node.
Solution:
Compaq is working with Microsoft to resolve this issue.
Frequent SCSI Timeouts and Disk Errors During Disk Failovers
When cluster disk groups are moved, or failed over, there are errors reported by the Windows
disk and HBA drivers. The Windows disk driver will report errors encountered during paging
operations in the System Event log (event 51). The Compaq cpqkgpsa.sys driver will report SCSI
timeouts (event 9).
Solution:
Compaq is working with Microsoft to resolve this issue.
Extended Screen Blackout During the Installation of the Operating System
When first installing the Windows Advanced Server, Limited Edition operating system, the
display may black out for one and a half to two minutes. This black out occurs after the device
drivers are first loaded and before Windows prompts the user to begin the installation by pressing
the Enterkey. The server is not locked and the installation will continue normally.
Solution:
Compaq is working with Microsoft to resolve this issue.
Disk Management Refresh Issues
If the Disk Management utility is open on a cluster node while a group is moved from or to that
cluster node, the Disk Management utility may produce unreliable disk information. The disk
resources that are moved may appear in Disk Management blanked out or unreadable.

Clustering Tips for Microsoft Windows Advanced Server, Limited Edition on Compaq ProLiant DL590/64 Server 12
Solution:
To resolve this issue, perform a disk rescan and restart Disk Management.
Ghost Volume Images Exist Following Storage Reconfiguration
If access to the storage system is momentarily broken from all cluster nodes (for instance, by
resetting the controllers or rebooting the fiber switch), the cluster service will lose access to the
quorum. The cluster service will shutdown and retry access in a minute. When the storage system
is accessible and the cluster service successfully restarts, some hosts may have volume images.
These “ghost” volumes are disk resources owned by other hosts before the storage system went
down. There is limited list and read access to these volumes. A reboot of the host will clear these
“ghost” volumes.
Solution:
Compaq is working with Microsoft to resolve this issue.
Controller Does Not Fail a Raidset When Two Drives Are Removed From a
RAID 5 LUN
When two drives are removed from a RAID 5 unit, the controller may not mark the unit as failed.
If the units are replaced in their original slots, the controller may mark the unit as online with
only one disk marked as failed.
Solution:
Compaq is working to resolve this issue.
Cluster Service Hangs Are Reported After Boot
The cluster service may report in the event logs that it could not start after boot. The cluster
service then logs a successful start seconds later.
Solution:
Compaq is working with Microsoft to resolve this issue.
