NOTE: Since Datacenter Server is one of four operating systems in the Windows 2000 platform, some of the core services incorporated within Datacenter Server are common to all Windows 2000 platforms. In the following sections, “Win­dows 2000” is used to identify the services common to all Windows 2000 platforms and “Windows 2000 Datacenter Server” is used to identify services and components specific to the Datacenter Server platform.
Overview of a Dell PowerEdge Cluster FE100/FL100 Datacenter Server Configuration
The PowerEdge Cluster FE100/FL100 Datacenter Server is a cluster solution that implements 2-node to 4-node clustering technology based on the Microsoft Windows 2000 Cluster Service (MSCS) software incorporated within the Windows 2000 Datacenter Server operating system.
NOTE: In this guide and in other cluster documentation, MSCS is also referred to as Cluster Service.
PowerEdge Cluster FE100/FL100 Datacenter Server solutions provide the following benefits in meeting the needs of mission-critical network application programs:
• High availability of system services and resources to network clients
• Redundant storage for application program data
• Failure recovery for cluster application programs
• Flexible maintenance capabilities, allowing you to repair, maintain, or upgrade a
cluster node without taking the entire cluster offline
• Load balancing between the cluster nodes
A PowerEdge cluster consists of two or more PowerEdge 8450 server systems (referred to as cluster nodes) that are interconnected with hardware and software components, providing a single point of continuous access to network services (including file systems, databases, enterprise resource planning [ERP], and other application programs, and services) for network clients. Each cluster node is config­ured with software, storage, and network resources that enable it to monitor and interact with the other nodes to provide mutually redundant operation. Because the cluster nodes interact in this way, they appear as a single system to the network clients.
In a standard client/server environment, a user accesses a network resource by con­necting to a physical server with a unique Internet Protocol (IP) address and network name. If the server fails for any reason, the user will no longer be able to access the resource. In a cluster environment, a user does not access a physical server, but a vir- tual server—a network resource managed by the Cluster Service that is not associated with a physical server, and can failover to another cluster node. Virtual servers are designed to dynamically reconfigure user resources during a connection or hardware failure, providing a higher availability of network resources as compared to a nonclustered PowerEdge system.

NOTE: For more information on failover, failback, and groups, see “Configuring Failover and Failback Support” in Chapter 6, “Configuring the System Software.”
SAN-Attached Cluster Configuration
A PowerEdge Cluster FE100/FL100 Datacenter Server configuration is a SAN-attached cluster configuration where all four cluster nodes are attached to a single PowerVault™ storage system or to multiple PowerVault storage systems through a Dell PowerVault SAN using a redundant Fibre Channel switch fabric.
NOTE: A PowerEdge Cluster FE100/FL100 Datacenter Server configuration cannot coexist on the Fibre Channel switch fabric with other clusters or stand-alone servers.
A Fibre Channel switch fabric is an active, intelligent, and private connection of one or more fibre channel switches that provide high-speed, point-to-point connections between servers and storage devices. Using instructions that are programmed into the switch, the switches in a Fibre Channel fabric provide point-to-point connection through inbound and outbound points from one device (sender) to another device or switch (receiver) on the network. If the data is sent to another switch, the process repeats itself until a connection is established between the sender and the receiver. One or more PowerVault Fibre Channel switches make up a Fibre Channel fabric.
Figure 1-1 shows an advanced SAN-attached cluster configuration.

in terms of price and performance because one cluster node sits idle all of the time.
support.dell.com Getting Started 1-5

However, this configuration is appropriate for business-critical systems since the application can use the full power of another cluster node in case one cluster node fails.
NOTE: For clarity, future references of activen/active and activen/passive configura­tions will use “n” to equal the number of active cluster nodes. For example, an active/active/active/active configuration consisting of four active cluster nodes will be referred to as an active
4
configuration.
Failover and Failback Support
One of the key features of Cluster Service is failover and failback support. Failover is the process of automatically moving resources from a failed cluster node to other healthy node(s) in the cluster. Failback is the process of returning the resources back to the original cluster node. Both failover and failback can be an automatic or manual process, depending on how you configure the Cluster Service.
NOTE: For more information on failover, failback, and cluster groups, see “Configuring Failover and Failback Support” in Chapter 6, “Configuring the System Software.”
PowerEdge Cluster FE100/FL100 Datacenter Server Failover Options
The PowerEdge FE100/FL100 Datacenter Server configuration provides the following failover options:
• N + 1
• Multiway
• Cascading
• N-Way migration solution
The following subsections describe each of these failover options.
N+1 Failover
N+1 failover is an activen/passive failover solution where one cluster node provides backup for multiple cluster nodes. This solution provides the following features:
Advantage:
• One cluster node is a dedicated backup node for all cluster nodes, providing the
best solution for critical applications.
Disadvantages
• High expense, as one node is not used to provide network resources.
• Backup cluster node may lack the resources to support multiple cluster node
failures.
Figure 1-2 shows an example of N + 1 failover configuration.

Figure 1-2. N+1 Failover
Table 1-3 provides a N+1 failover configuration for the cluster shown in Figure 1-2. For each cluster resource group, the failover order in the Preferred Owners list provides the order that you want that resource group to failover. If that resource group or its cluster node fails, the cluster will try to fail that resource group to the first available node in the list. In this example, node 1 owns cluster resource group A, node 2 owns cluster resource group B, and node 3 owns cluster resource group C. Cluster resource groups A, B, or C would failover to cluster node 4, if cluster node 1, 2, or 3 fails, respectively.

NOTE: When implementing this type of failover solution, failback should be config­ured if the cluster node lacks the resources (such as memory or processing power) to support one or more cluster node failures.
Multiway Failover
Multiway failover is an activen/active failover solution where running applications from a failed node migrate to multiple nodes in the cluster. This active failover provides the following features:
Advantage:

Table 1-4 provides an example of a multiway failover configuration for the cluster shown in Figure 1-3. For each cluster resource group, the failover order in the Preferred Owners list outlines the order that you want that resource group to failover. In this example, node 1 owns cluster resource groups A, B, and C. If node 1 fails, the cluster resource groups A, B, and C will failover to cluster nodes 2, 4, and 3, respec­tively. The cluster resource groups on cluster nodes 2, 3, and 4 need to be configured similarly.

C 1, 3, 4, 2
NOTE: When implementing this type of failover solution, failback should be config­ured to avoid performance degradation.
Cascading Failover
With Cascading failover, all running applications migrate from the failed node to the next preassigned cluster node. If you do not make a failover selection, cascading failover will be the default failover type. This type of failover provides the following features:
Page 21
Advantage:
• High resource availability to users.
Disadvantage:
• The cluster node next in line for failover may not have ample resources available
to handle the additional workload of the failed node.

CHAPTER 3
Preparing PowerEdge and PowerVault Systems for Clustering
This chapter provides the necessary steps for performing the following procedures:
• Adding peripherals to your cluster
• Configuring Fibre Channel host bus adapters (HBAs) on separate peripheral com-
ponent interconnect (PCI) buses
• Configuring disk processor enclosure (DPE) and disk array enclosure (DAE)
addresses
Adding Peripherals to Your Cluster
WARNING: Hardware installation should be performed only by trained service technicians. Before working inside the computer system, see the safety instructions in your Dell PowerEdge System Information document to avoid a situation that could cause serious injury or death.
You may need to add peripheral devices and expansion cards to the system to meet the minimum cluster requirements for a PowerEdge FE100/FL100 Datacenter Server configuration. For example, each cluster node must have two network interface con­troller (NIC) cards to meet the minimum configuration requirements and two HBAs to enable node-redundant access to the shared storage system.
If you are adding storage area networking (SAN) components, see Chapter 10, “SAN Components” for more information on supported configurations and components.
If you are upgrading an existing PowerVault storage system to meet the cluster requirements for the shared storage subsystem, you may need to install additional Fibre Channel hard-disk drives in the shared storage system. The size and number of drives you add depend on the redundant array of independent disks (RAID) level you want to use and the number of Fibre Channel hard-disk drives already present in your system.
For information on installing Fibre Channel hard-disk drives in the PowerVault storage system, see the Installation and Troubleshooting Guide for your PowerVault storage system.

For instructions on installing expansion cards or hard-disk drives in your node, see the Installation and Troubleshooting Guide for your PowerEdge system.
Configuring Fibre Channel HBAs on Separate PCI Buses
Dell recommends configuring Fibre Channel HBAs on separate PCI buses. While con­figuring the adapters on separate buses improves availability and performance, this recommendation is not a requirement.
The following list provides the PCI slot assignment information for the PowerEdge 8450 system PCI buses, RAID controllers, HBAs, and the Dell OpenManage Remote Assistant Card (DRAC).
• PCI buses
— PCI bus 0: PCI slot 1 and 2 are 64-bit, 33-MHz.
— PCI bus 1: PCI slots 3 through 6 are 64-bit, 33-MHz.
— PCI bus 2: PCI slots 7 and 8 are 64-bit, 33/66-MHz
— PCI bus 3: PCI slots 9 and 10 are 64-bit, 33/66-MHz.
• RAID controllers
— Install the RAID controller for the system’s internal drives in PCI slot 1.
• HBAs
— For dual HBA configurations, Dell recommends installing the HBAs on sepa-
rate PCI buses (PCI buses 2 and 3, which includes PCI slots 7 through 10) to balance the load on the system.
• DRAC
— If you are currently using a DRAC or plan to use one in the future, install it in
PCI slot 2.
Configuring PowerVault DPE and DAE Enclosure Addresses
When adding a PowerVault DAE to a PowerVault DPE, each DAE must have a unique enclosure address (EA). Be sure to set the EA of each enclosure attached to a PowerVault DPE to a unique value.
See the Installation and Troubleshooting Guide for your PowerVault storage system for more information on setting enclosure addresses.

These systems and components are intercon­nected to provide four independent functions listed below, each of which is described in more detail throughout this chapter:
• Shared storage system—Connects the servers' redundant host bus adapters
(HBAs) to the cluster's shared storage system. The server-to-storage connection can be achieved through a direct connection or through a storage area network (SAN). See Chapter 10, “SAN Components,” for more detailed information on SAN configurations.
• Cluster interconnect (private network)—Connects the cluster nodes to each
other to exchange cluster information and health status, such as the cluster heart­beat and access to the quorum resource. This connection can be made by using a Broadcom NetExtreme Gigabit Ethernet network interface controller (NIC) (for the FE100) or Giganet cLAN 1000 NIC (for the FL100) with Category 5 (CAT 5) or cLAN cabling, respectively, connected to each cluster node.
• Network connection for public traffic (public network)—Provides a connec-
tion between each cluster node and the public network. This connection can be made using the Broadcom NetExtreme Gigabit Ethernet NIC and Category 5 (CAT 5) ethernet cabling or the Intel PRO/1000 Gigabit Server Adapter and fibre optical cabling to connect the NIC to the public network.

Page 34
• Power connection - Provides a connection between the power supplies in your
system and the power source. By using power strips or power distribution units (PDUs) and separate AC circuits, the cluster can fully utilize the redundant power supplies.
Fibre Channel Copper Connectors
To connect a PowerVault storage system to a PowerEdge system (cluster node), Dell uses the DB-9 connector and the high-speed serial data connector (HSSDC). The DB­9 connector, shown in Figure 4-1, attaches to the PowerVault disk-processor enclo­sure (DPE) and PowerVault disk-array enclosure (DAE).
Figure 4-1. DB-9 Connector
The HSSDC, shown in Figure 4-2, attaches to the HBA on the PowerEdge systems and the copper connections to the gigabit interface converters (GBICs) on the Power­Vault Fibre Channel switch. The connector is used on the PowerVault DAE and all Giganet connections.
Figure 4-2. HSSDC Connector
NOTES: Fibre Channel HSSDC cables should not be used to connect Giganet HSSDC devices because they are not properly shielded for Giganet use.
4-2 User’s Guide
Page 35
Fibre Channel devices using HSSDC connections must not be connected directly to Giganet devices using HSSDC connections.
Cabling Your Public Network
The NICs in the PowerEdge systems (cluster nodes) provide at least two network connections for each cluster node—a dedicated private network (cluster interconnect) between the nodes and a public network connection to the local area network (LAN). NICs connected to the LAN can also provide redundancy at the communications level in case the cluster interconnect fails. See your Microsoft Cluster Service (MSCS) doc­umentation for more information on cluster interconnect redundancy.
Using NICs in Your Public Network
Connection to the public LAN is provided by a Broadcom NetExtreme Gigabit Ether­net or Intel PRO/1000 Gigabit Server Adapter installed in each node. The Dell PowerEdge Cluster FE100/FL100 Datacenter Server supported NICs running Trans­mission Control Protocol/Internet Protocol (TCP/IP) may be used to connect to the public network. Additional NICs may be installed to support additional separate public LAN segments.
Cabling Your Private Network
Your cluster configuration can use Broadcom NetExtreme Gigabit Ethernet NICs or Giganet cLAN 1000 host bus adapters for the private network (cluster interconnect).
The private network is established by using a network switch and/or Giganet cLAN switch. You can use standard Ethernet cables to connect these Broadcom NetExtreme Gigabit Ethernet NICs to a network switch or the GigaNet cable to con­nect from the Giganet adapter to the cLAN GigaNet switch.
The private network can be used for intracluster communications, intercluster com­munications, or a separate, dedicated network, which can provide some or, all of the following features depending on the applications:
• Database replication, snapshots, and synchronization
• High-speed network backup
• Application-to-database communications
• Web server-to-application or web server-to-database communications
Using Broadcom NetExtreme Gigabit Ethernet Controllers in Your Private Network
The private network is established by using a straight-through Category 5 (CAT 5) unshielded network cable to connect the Broadcom NetExtreme Gigabit Ethernet NICs to the private network through a network switch.

Using Giganet cLAN for the Private Network
PowerEdge Cluster FE100/FL100 Datacenter Server systems can be connected to each other using the following Giganet high-speed interconnect products:
• GigaNet cLAN host adapters
• Giganet cabling
• Giganet cLAN cluster switches
Giganet cLAN 1000 HBAs provide high band-width, low-latency server-to-server, server-to- cluster, and cluster-to-cluster interconnections. A faster network connec­tion, however, will not increase the speed of application failover on a cluster or enable an application to failover to a PowerEdge server (cluster node) outside of the cluster.

Protecting Your Cluster From Power Failure
Dell recommends the following guidelines to protect your cluster configuration from power-related failures:
• Use uninterruptible power supplies (UPS) for each cluster node
• Implement backup generators and power from separate electrical stations
(depending on your situation and environment)
NOTE: See your server and storage system documentation for more information on the specific power requirements for your cluster system's components.
Connecting Standby Power Supplies in the PowerVault System
PowerEdge Cluster FE100/FL100 Datacenter Server configurations require dual standby power supplies (SPS) in the PowerVault storage system. This configuration provides maximum integrity of the storage processor write-cache. The SPS allows the write-caching to complete in the event that the primary power supply fails.
Figure 4-5 shows the location and cabling for the SPS units in the PowerVault system.

Configuring the LUNs and RAID Level for the Shared Storage Subsystem
The storage system hard-disk drives must be bound into logical unit numbers (LUNs) using the Dell OpenManage Data Supervisor or Dell OpenManage Data Administrator.
All LUNs, especially the LUN used for the Microsoft Cluster Server (MSCS) quorum resource, should be bound using a redundant array of independent disks (RAID) level to ensure high availability. See “Cluster Quorum Resource“in Chapter 6, “Configuring the System Software” for more information on the quorum resource.
NOTICE: Dell recommends that you use a RAID level other than RAID 0 for your PowerVault shared storage system. RAID 0 does not provide the level of availability required for the quorum resource. See the Installation and Troubleshooting Guide for your PowerVault storage system for more infor­mation about setting up RAID levels for the system.
Configuring Internal SCSI Hard-Disk Drives
If you have added new hard-disk drives to your cluster node or you are setting up the internal drives in a redundant array of independent disks (RAID) configuration, you must configure the RAID before you can install the operating system. For instructions on setting up the internal drives, see the appropriate small computer system interface (SCSI) controller or RAID controller documentation for your system.
RAID Level for the Internal SCSI Hard-Disk Drives
Configure the hard-disk drives using the RAID controller's basic input/output system (BIOS) configuration utility. For optimum balance of fault tolerance and performance with a limited number of drives, the recommended configuration for the internal drives is RAID 1.
NOTE: Most of the RAID hard-disk drives should be in the shared storage system.
For more information on RAID configurations, see the documentation for your specific PowerEdge RAID controller.

(see Chapter 4, “Cabling the Cluster Hardware”)
support.dell.com Configuring the System Software 6-1
Page 42
• Configure the storage systems and small computer system interface (SCSI)
drives attached to your Dell PowerEdge Clusters FE100/FL100 Datacenter Server system (see Chapter 5, “Configuring Storage Systems (Low-Level Configuration))”
NOTICE: When you install Datacenter Server, do not enable the standby mode or hibernation mode incorporated in Windows 2000 Datacenter Server. These modes are not supported in cluster configurations.
When you install Datacenter Server, you must configure the operating system to enable clustering. These configuration requirements are described in the Microsoft Windows 2000 Datacenter Server documentation. The following sections briefly dis­cuss these configurations.
Configuring the Cluster Nodes in a Windows 2000 Domain
Windows 2000 operates on a domain model in a server-based network. In a Windows 2000 cluster, all of the cluster nodes must belong to a common domain—a logical grouping of servers (such as cluster nodes) that share a common database and security policy.
In a Windows 2000 cluster domain, all cluster nodes are assigned one of the follow­ing tasks:
• Domain controllers—A cluster node that contains the master copy or a copy of
the domain security policy and domain database, and authenticates user logon to the network. Multiple domain controllers provide redundancy for the network if one of the domain controllers goes offline.
• Member servers—A cluster node that is not a domain controller and usually
provides user resources as a file, application, database, or remote access server (RAS).
The Dell PowerEdge Cluster FE100/FL100 Datacenter Server configuration supports the following domain assignments for each cluster node:
• All cluster nodes are member servers in a Windows 2000 domain.
• All cluster nodes are member servers in a Windows 2000 Active Directory
domain.
• All cluster nodes are domain controllers in a Windows 2000 Active Directory
domain.
• One cluster node is a domain controller in a Windows 2000 Active Directory
domain and the other cluster node is a member server in that domain.
If a cluster node is not a domain controller and is unable to contact a domain control­ler, the cluster node will not be able to authenticate client requests. If a cluster node is a domain controller, client access to the cluster node’s cluster resources may be discontinued if the cluster node cannot contact the remaining domain controller(s).
6-2 User’s Guide
Page 43
NOTE: Domain controller functions may cause additional logon, authentication, and replication traffic and overhead on the node.
Configuring the Windows 2000 Cluster Service
To configure the Windows 2000 Cluster Service during the Windows 2000 Datacenter Server installation, perform the following steps:
1. Ensure that you have performed the tasks in the section, “Preparing for Microsoft Windows 2000 Datacenter Server Installation,” found earlier in this chapter.
2. Click the Start button, and point to Settings—> Control Panel.
3. Click Add/Remove Programs.
4. Click Add/Remove Windows Components.
5. Click Configure next to Configure Cluster Service.
The Cluster Service Configuration Wizard appears.
Follow the steps in the wizard to complete the installation.
When you configure the Cluster Service, you are prompted to assign a function for the public and private networks. To provide added fault tolerance for the pri­vate network, Dell recommends that you configure the private network by performing the following steps:
a. Set the private network to Use for internal communications only.
NOTE: Dell suggests that you rename your private network to avoid confusion.
b. Set the public network to All communications.
This setting provides a redundant path for the cluster-to-cluster communica­tion in the event the private network fails.
c. Set each subsequent NIC to Public communications only.
d. Assign the private network with the highest priority for internal
communications.
If you did not check the box for Cluster Service during the Windows 2000 Datacenter Server installation, perform the following steps:

Configuring the Public and Private Networks
Configuring the public and private networks correctly in each node is critical to install­ing the Cluster Service. The following subsections provide the principles and procedures necessary to configuring your network.
Static IP Address
A static Internet Protocol (IP) address is an Internet address that a network adminis­trator assigns exclusively to a system or a resource. The address assignment remains in effect until the network administrator changes the address.
The Cluster Service requires a static IP address for the name of each cluster node in order to manage the cluster. Because each node in a cluster has at least two NICs for
6-4 User’s Guide
Page 45
both the public and private networks, the minimum number of static IP addresses required for a four-node clustering is nine—two for each NIC in the cluster nodes and one for the cluster.
Cluster-aware applications running on the cluster may require additional IP addresses. For example, Microsoft SQL Server requires at least one static IP address for the vir­tual server (Microsoft SQL Server does not use the cluster's IP address). Also, each cluster node containing Internet Information Server (IIS) that is configured for failover requires a unique static IP address.
Configuring the IP Addresses for the Private Network
A PowerEdge Cluster FE100/FL100 Datacenter Server configuration requires at least two NICs in each PowerEdge server (cluster node), with each NIC dedicated to one of the following networks:
• Public network (local area network [LAN])
• Private network (node-to-node communications through the cluster interconnect)
Attaching two networks to the cluster enables fault tolerance for cluster communica­tions. If the cluster interconnects fails, the cluster can still use the public network for cluster communications.
The NICs installed in a cluster node must reside on different IP subnets with the cluster interconnect assigned to a separate IP subnet or a different network ID than the LAN subnet(s) used for a client connection.
Dell recommends using the static IP address assignments in Table 6-1 for the NICs assigned to the private network.
Table 6-1. IP Addresses for the Private Network
Cluster Node IP Address Subnet Mask
Node 1 10.0.0.1 255.255.255.0
Node 2 10.0.0.2 255.255.255.0
Node 3 10.0.0.3 255.255.255.0
Node 4 10.0.0.4 255.255.255.0
NOTE: The IP address assignments for the public LAN segments may vary according to your network environment.
If multiple private network NICs are connected to a network switch, make sure that all of the NICs connected to the private network have a unique IP address. For NICs con­nected to the private network in any other cluster connected to the same switch, you can continue the IP address assignment displayed in Table 6-1 by using 10.0.0.5 and
10.0.0.6, and continuing the address assignment scheme for any additional NICs con­nected to a private network NIC in the same cluster.
The IP address assignments for the public network may vary according to your net­work environment. If the IP assignments are set up correctly, all of the NIC resources
support.dell.com Configuring the System Software 6-5
Page 46
will respond to ping commands and will appear online after installing Cluster Service (MSCS) on the cluster nodes. If the IP address resources are not set up correctly, the cluster nodes may not be able to communicate with the domain and the Windows 2000 Cluster Configuration wizard may not allow you to configure all of your networks.
Installing and Configuring Your Windows 2000 Datacenter Server Network
The following sections describe an example for using Windows 2000 for configuring your PowerEdge Cluster FE100/FL100 Datacenter Server network.
NOTE: The IP addresses for the public network, default gateway, domain name sys­tem (DNS) servers, and Windows Internet naming service (WINS) servers used here are examples and are not representative of actual addresses that should be used for your environment.
Overview of a Windows 2000 Datacenter Server Network Installation
The Windows Networking Components wizard detects each individual adapter installed in your system and allows you to configure them separately. If your adapter is not detected by Windows 2000, you will need to manually add its Windows 2000 digitally-signed driver. If there are two or more identical NICs installed in the cluster node, it may be difficult to determine which NIC you are trying to configure.
There are several factors that can determine how Windows 2000 scans the peripheral component interconnect (PCI) buses. If you cannot communicate with the domain or cannot ping other adapters on the same subnet after you have completed the follow­ing steps, you must reconfigure Transmission control protocol/Internet protocol (TCP/IP).
Table 6-2 provides the configuration information that is used in the following procedure.

13. After completing the network configurations for the NICs installed in the cluster
®
nodes, select the option to join a Windows NT
or Windows 2000 domain. When prompted, enter a user account with account operator or administrator privileges on the domain.
NOTE: If you receive an error message indicating that the domain cannot be found, verify that a network link is present using the light emitting diode (LED) indicators on the NICs (if available) and that the TCP/IP configuration is correct, including the default gateway, DNS server(s), and WINS server(s).
If problems persist, ensure that each NIC is configured for the correct network. If this problem occurs, switch the NIC cables (if both NICs are identical) or reconfig­ure the TCP/IP addresses for each NIC.
14. Repeat steps 1-13 for other cluster nodes using unique static IP addresses for each networking segment. Be sure to use the same network subnet for each net­work segment used on Cluster Node 1.
Updating the Host Bus Adapter Driver
Windows 2000 Datacenter Server automatically detects and installs a driver for some host bus adapters (HBA). Before you configure the shared storage system, you must update this driver with the latest driver version.

Windows 2000 Cluster Service recognizes the logical drives of the shared storage system only if the drives are partitioned, formatted using Windows NT File System (NTFS), assigned drive letters, and configured as basic disks (as opposed to dynamic disks). Also, the assigned drive letters for each shared storage partition must be iden­tical on both nodes.
To assign drive letters and format shared hard-disk drives, perform the following steps:
1. C l i ck t h e Start button, select Programs, select Administrative Tools, and click Computer Management.
2. Select the Disk Management folder to display Windows drive configuration set­tings. If you are using the Disk Management tool for the first time, the Write Signature and Upgrade Disk wizard appears.
A list of all shared drives is displayed in the Disk to Write Signature window.
NOTE: If the Upgrade Disk wizard does not appear and the unformatted drives are not visible, verify that the updated HBA driver is installed and that the Cluster Service is not installed and running on another cluster node. If the Cluster Service is running on another cluster node, you cannot configure the shared storage disks.
3. Click the check box for each disk, and then click Next.
4. In the Select disks to be upgraded window, deselect all checked boxes.
5. Click Next.
The disk configuration information appears.
NOTICE: The upgrade procedure creates dynamic disks or volumes from the selected disks that can not be used by Cluster Service. Before you proceed to the following step, ensure that the disks are not being upgraded by deselecting each disk.
support.dell.com Configuring the System Software 6-11
Page 52
The right column shows the shared drives as raw, unformatted drives, with unal­located disk capacity. The left column shows Basic disks.
If the left column shows Dynamic disks, right-click that box and select Revert to Basic for each disk in the shared storage system.
NOTICE: Reverting disks to Basic destroys all data on the drive.
6. For each shared disk, run the Create Partition wizard by performing the following
steps:
e. In the row for the first shared disk, right-click over the right-column box.
f. Select Create Partition, and then click Next.
g. Select Primary partition, and then click Next.
h. In the next dialog box, Dell recommends choosing all available disk space.
NOTE: For additional information on partition size recommendations, see “Cluster Quorum Resource,” found later in this chapter.
If you create multiple partitions on a single disk, the partitions will not be able to individually move between the cluster nodes. All partitions on a given disk move together. Therefore, Dell recommends that you run separate applications on sep­arate disks, rather than using separate partitions on the same disk.
You may want to create a separate partition on one of your shared storage disks for the quorum resource log files. For more information, see “Installing and Con­figuring the Windows 2000 Cluster Service,“found later in this chapter.
i. In the next window, select the drive letter and the disk format parameters.
NOTE: All shared storage drives must be formatted with NTFS.
j. Review the selections in the windows and click Finish.
After formatting is complete, the right column for each drive shows a health status of Healthy.
Using the Windows 2000 Dynamic Disks and Volumes
Windows 2000 does not support the use of dynamic disks (upgraded disks) or vol­umes for shared storage disk drives. If shared storage disk drives are configured as dynamic disks, the Cluster Configuration wizard will not be able to discover and access the disks. If your shared storage disk drives are already configured as dynamic, see the previous section, “Assigning Drive Letters and Formatting Drives on the Shared Storage System” for the procedure on changing dynamic disks to basic disks.

Verifying Cluster Readiness
Before you install Cluster Service in the PowerEdge cluster nodes and the PowerVault storage systems, check the system and verify that the cluster meets the following conditions:
• All cluster nodes are able to log in to the domain.
• The shared drives are partitioned, formatted, and named on each node.
• All IP addresses and network names for each NIC and each cluster node can
communicate with each other.
For example, open a command prompt and use the ping command to verify clus- ter node communications.
Installing and Configuring the Windows 2000 Cluster Service
When you install Windows 2000 Datacenter Server and install the Cluster Service, the Cluster Service configuration files are copied to the system. Before you configure a PowerEdge server as a cluster node, Cluster Service must be configured using the Cluster Configuration wizard.
See Microsoft's online help for configuring the Cluster Service located at http://www.microsoft.com.
The following subsections explain some of the necessary procedures for installing and configuring Windows 2000 Datacenter Cluster Service.
Cluster Quorum Resource
A quorum resource is typically a hard-disk drive in the shared storage system that serves the following purposes in a Cluster configuration:
• Provides Windows 2000 with a list of active nodes that can communicate with
each other so the operating system can form a working cluster
• Acts as an arbiter between the cluster nodes to ensure that the specific data
necessary for system recovery is maintained consistently across the nodes
• Logs the recovery data sent by the cluster node
Only one cluster node can control the quorum resource at a time, and this cluster node remains running when it cannot communicate with the remaining nodes in the cluster. If the cluster node containing the quorum resource is unable to communicate with another cluster node, the Cluster Service automatically shuts down the node that does not control the quorum resource.
If one of the cluster nodes fails, any changes to the cluster configuration database are logged to the quorum disk. This logging process occurs to ensure that the node that gains control of the quorum disk can access an up-to-date version of the cluster con­figuration database.
support.dell.com Configuring the System Software 6-13
Page 54
Cluster Resource Group
When you create a new cluster, the cluster will contain (by default) a cluster group that contain the default settings and resources for the cluster. This group contains a list of the cluster resources, which includes the following:
• Cluster IP address
• IP network name (cluster network resource name)
• Quorum disk
When you install the Cluster Service and configure the cluster in the Cluster Configuration wizard, the IP address and the name of the cluster you enter in the
wizard becomes the IP address and IP network name of the cluster. If you prefer to relocate the quorum disk, you can move the quorum disk to another disk group.
Adding Additional Applications and Data to the Quorum Disk
The quorum disk, by default, is installed in the “Cluster Group.” Dell recommends that you do not install additional applications into the Cluster Group. The Cluster Group also contains a network name and IP address resource, which is used to man­age the cluster. However, if you choose to use the quorum disk for applications and data, Dell recommends that you perform the following steps:
1. Create a small partition on one of the shared RAID drives.
2. Allocate 100 megabytes (MB) to the partition.
One hundred megabytes (MB) (100 MB) is a satisfactory size for this partition, but no other applications or data should be stored there.
3. Assign a drive letter to the partition.
4. Assign the Cluster Service files (quorum disk) to this drive letter during installa-
tion.
This procedure will prevent other application programs or data from filling the par­tition where the quorum resource is located.
NOTICE: If the quorum disk's partition becomes full, the quorum resource is not able to expand and may become corrupt. If a separate partition is not used for the quorum resource, ensure that the quorum disk’s partition does not become full when used by other applications or files.
You can place applications and data on the remaining partitions or space on the shared disk with the quorum resource partition. These partition(s) must be placed in the same cluster group as the quorum resource partition to ensure failover consistency.
5. Move the quorum disk (which the quorum resource partition) out of the cluster group and into another group.
6-14 User’s Guide
Page 55
The status of any applications and data using the quorum disk will not affect the status of the Cluster Group.
NOTE: For information on moving the quorum files, see Microsoft's online help.
Because the quorum disk plays a crucial role in cluster operation, losing the quorum disk will cause the entire cluster to fail. To prevent this type of failure, configure the quorum resource on a shared disk drive protected by a fault tolerant redundant array of independent disks (RAID) set, preferably on a volume that spans multiple storage enclosures.
Verifying Cluster Functionality
To ensure that a PowerEdge FE100/FL100 Datacenter Server Cluster configuration functions properly, check the system's functionality and configuration settings and verify that the cluster meets the following conditions:
• All IP addresses and network names in the cluster are communicating with each
other and other components in the network.
• The Cluster Service is running.
• All resources and recovery groups are online.
• All resources and recovery groups come online on the remaining cluster node(s)
after manually moving them.
Verifying Cluster Service
The Cluster Service manages all of the activity on the cluster node, including mem­bership management, communication management, and failover management. When Cluster Service is properly installed, it starts on each cluster node and responds auto­matically in the event that one of the nodes fails or goes offline.
To verify that Cluster Service is running on the cluster node, perform the following steps:
1. C l i ck t h e Start button and select Programs—> Administrative Tools—> Services.
The Services window appears.
2. Confirm that Cluster Service is started and that it is set to start automatically.
Verifying Cluster Resource Availability
In the context of clustering, a resource is a basic unit of failover management. Appli­cation programs are made up of resources that are grouped together for recovery purposes. All recovery groups—and therefore the resources that comprise the recov­ery groups—must be online (or in a ready state) for the cluster to function properly.
support.dell.com Configuring the System Software 6-15
Page 56
To verify that the cluster resources are online, perform the following steps on the monitoring cluster node:
1. Click the Start button and select Programs—> Administrative Tools—> Cluster Administrator.
2. Open a connection to the cluster and check the running state of each recovery group. If a group has failed, one or more of its resources may be offline.
Troubleshooting the failed resources is beyond the scope of this document, but exam­ining the properties of each resource and ensuring that the specified parameters are correct are the first two steps in this process. In general, if a resource is offline, it can be brought online by selecting it, right-clicking it, and selecting Bring Online from the pulldown menu. For information about troubleshooting resource failures, see the Microsoft Cluster Service help files.
Configuring the Dell OpenManage Manage Node (Data Agent) for a Cluster Environment
The following procedure provides the necessary steps to configure your Dell OpenManage Managed Node (Data Agent) for clustering.
To configure the Dell OpenManage Managed Node (Data Agent) in a cluster, perform the following steps:
1. O p e n t h e Agent Configurator.
2. In the Host Description field, type the description of the server.
3. In the Contact Person field, type the name of the contact person (optional).
4. Click the Enable Cluster Support check box to enable the new cluster support functionality.
5. In the Devices pulldown menu, click Auto-Detect.
This selection forces the Agent Configurator to discover the RAID configuration of the storage subsystem.
6. In the Privileged Users field, type the name(s) of the privileged user(s).
7. In the File pulldown menu, click Save to save the new configuration.
Configuring the Data Agent for Cluster Failover
The Dell OpenManage Managed Node (Data Agent) should be installed as a cluster resource and managed by the Cluster Service so only one Data Agent is running at
6-16 User’s Guide
Page 57
any one time. Only one Data Agent should be running to ensure that the nodes have a consistent view of the PowerVault storage system.
To install the Data Agent as a cluster resource, perform the following steps:
1. Confirm that Dell OpenManage Managed Node (Data Agent) is installed on all of the cluster nodes and is configured to start manually.
2. Open the Cluster Administrator.
3. Right-click Cluster Group, point to New, and click Resource.
4. In the Name field, type Manage Node Agent.
5. In the Resource Type menu, select Generic Service.
6. Click Next.
7. In the Possible Owners window, verify that all of the cluster nodes appear in the window.
8. Click Next.
9. Highlight Cluster IP Address and Cluster Name, move them to the Resource Dependencies window, and then click Next.
Enabling these dependencies ensures that as soon as the Data Agent starts, the Administrator can connect to the Data Agent through the cluster IP address or the cluster name.
10. In the Service Name field, type Dell_OpenManage_Data_Agent and then click Next.
11. C li ck Finish.
12. Click OK.
13. Right-click the new resource and select Properties.
The Properties window appears.
14. Deselect Affect group and click OK.
15. Right-click Cluster Group and select Bring Online.
If the resource is online, a message window appears stating “Dell OpenMan- age Data Agent has started.”
NOTE: When the Dell OpenManage Managed Node Agent is installed as a generic resource in the cluster, the cluster software is responsible for managing the Data Agent. If you try to stop the Data Agent in the Control Panel or in the Agent Configurator, the cluster will try to start the Data Agent automatically. If this event happens, stop or start the Data Agent by using Cluster Administrator to bring the Managed Node Agent resource offline or online.

Configuring Failover and Failback Support
When an individual application or user resource (also known as a cluster resource) fails on a cluster node, Cluster Service will detect the application failure and try to restart the application on the cluster node. If the restart attempt reaches a preset threshold, Cluster Service brings the running application offline, moves the application and its resources to another cluster node, and restarts the application on the other cluster node(s). This process of automatically moving resources from a failed cluster node to other healthy cluster node(s) is called failover.
When the system administrator repairs and restarts the failed cluster node, the oppo­site process occurs. After the original cluster node has been restarted and rejoins the cluster, the Cluster Service will bring the running application and its resources offline, move them from the failover cluster node to the original cluster node, and then restart the application. This process of returning the resources back to their original cluster node is called failback.
You can configure failback to occur at any given time, or not at all. However, be sure to configure the failback time during your offpeak hours to minimize the effect on users, as they may see a delay in service until the resources come back online.
In order to failover and failback running applications, cluster resources are placed together in a group so the Cluster Service can move the cluster resources as a com­bined unit. For example, an application such as Internet Information Server (IIS) requires a virtual disk, IP address, and a network name resource. IIS also requires a resource called “IIS Server Instance.” The IIS services and the IIS Server Instance resource can be placed in its own group and labeled, “IIS Group” for identification. Since the IIS Group (the resource group) contains all of the resources for the applica­tion (IIS), Cluster Service can bring all of the necessary components online in their proper order to ensure that failover and/or failback procedures transfers all of the user resources as transparently as possible.
6-18 User’s Guide
The following section provides information on failover support for 4-node clustering, and provides tables for each failover option that includes a preferred cluster node list for cluster group failover or failback that will help you implement your failover configuration.
Failover Support Through Four-Node Clustering
One of the key features of Datacenter Server is that it supports a 2-node, 3-node, and 4-node failover clustering solution. The PowerEdge FE100/FL100 Datacenter Server systems provide the 2-node to 4-node failover cluster solution and is designed to pro­vide higher levels of availability through improved service offering and additional cluster functionality.
When a failover situation occurs, the Cluster Service will take the resources offline and (by default) move them to the next cluster node number. For example, if cluster node 1 fails, Cluster Service will move the resources to the next cluster node number, which is cluster node 2. This default type of failover is called “Cascading failover.” After the malfunctioning cluster node is repaired and failback is enabled, Cluster Ser­vice will failback the resources using the same procedures as failover.
Page 59
You can also change the failover order for your resources by modifying the Preferred Owners list in the Modify Preferred Owners window, which is accessed through
Cluster Administrator. If some of your cluster nodes lack the resources to handle the additional workload of a failover application, rather than using the “Cascading failover” order (node 1—> node, 2—> node 3—> node 4), you can change the failover configu­ration to a preselected order of cluster nodes.
For example, if you know that node 2 and node 3 have ample resources to handle one application and nodes 1 and 4 are borderline, you can configure that application with this failover order: node 2—> node 3—> node 1—> node 4.
Modifying the Failover Sequence of the Disk Groups
To modify the failover sequence of the disk groups, perform the following steps:
1. Click the Start button and select Programs—> Administrative Tools—> Cluster Administrator.
2. Locate the disk group that contains the resources you want to failover in a pre­ferred failover order.
3. Right-click the disk group and select Properties.
The Properties window appears.
4. In the General tab, click Modify.
The Modify Preferred Owners window appears with a list of available cluster nodes in the left pane and a list of preferred owners in the right pane. The cluster nodes in the Preferred Owners pane are listed in order of failover attempt.
5. Reorder the disks groups by selecting a disk group and clicking the Up and Down arrows on the right side of the window.
6. Click OK.
The Properties window appears.
7. C l i c k OK.

support.dell.com Maintaining the Cluster 9-1
Page 68
PowerVault storage systems using one of the following graphical user interfaces (GUIs):
• Data Supervisor—allows you to configure and manage the disks and compo-
nents in a single PowerVault storage system, as well as bind and unbind logical unit numbers (LUNs), change configuration settings, and create LUNs.
• Data Administrator—provides the same capabilities as Data Supervisor, but also
allows you to configure and manage multiple PowerVault storage systems in a single GUI window.
NOTE: Data Agent must be installed on one of the cluster nodes with either Data Supervisor or Data Administrator.
The following subsection explains how to connect to the Data Agent using Data Administrator and Data Supervisor.
Connecting to Data Agent Using Data Administrator
To connect to the Dell OpenManage Data Agent using Data Administrator, perform the following steps:
1. Start Data Administrator.
2. In the Dell OpenManage Data Administrator Query dialog box, enter the name of the cluster that contains the Data Agent.
Using the cluster name to connect to the Data Agent ensures that Data Adminis­trator can always connect to the Data Agent, regardless of which cluster node is running the Data Agent.
NOTE: Do not enter the cluster node (server) name.
Identifying the Cluster Name
To identify the cluster name that is running Data Administrator, perform one of the following steps:
• Create a host file in your home directory containing the name of the cluster.
• Create a different file with the cluster name in another directory (not your home
directory) and specify the location of the file using the RAID_ARRAY_HOSTS variable.
• If the previous two options are not available, specify the cluster name in the
Data Administrator's Host Administration window.
NOTE: Do not run Data Administrator if you are using Dell OpenManage Data Management Station.
See the Dell OpenManage Data Agent Installation and Operation Guide and the Dell OpenManage Data Administrator Installation and Operation Guide, and the Dell PowerVault Storage Area Network (SAN) Administrator’s Guide for instructions on

(ATF) from the failed logical unit number (LUN). ATF will reestablish the communica­tion link between the cluster node and storage device, or reroute the connection through a secondary path. If multiple LUN failures occur in your cluster, run ATF from all of the cluster nodes.
To run ATF, perform the following steps:
1. O p e n a Command Prompt window.
2. Change to the directory where the ATF executable programs are stored.
For example, directory c:\\program files\dell openmanage\powervault manager\dell openmanage atf).
3. Type atf_restore atf_sp0 and press <Enter>.
The failed access path is restored.
For more information on using Dell OpenManage ATF, see the Dell OpenManage
ATF Operation Guide and the Dell PowerVault Storage Area Network (SAN) Administrator’s Guide.
Using the QLogic Fibre Channel Configura­tion Software for PowerVault 65xF Storage Processor Replacement
The QLogic Fibre Channel configuration utility is used in the event of a storage pro­cessor failure. When the failed storage processor is replaced with the new storage processor, the QLogic Fibre Channel configuration utility updates the list of worldwide name associations stored in the firmware of the HBA and eliminates the need to reboot the server in the event of a storage processor failure. This update must be performed on all of the cluster nodes.
You must run the QLogic Fibre Channel configuration utility each time the hardware on the SAN changes to create the appropriate settings for the replaced device.
If the failed storage processor is part of a zone, you need to update the alias, zone, and configuration information on the PowerVault 5xF switch after you replace the stor­age processor. See the Dell PowerVault 5xF Switches Zoning Guide for more information.
Determining the RAID Levels of the Shared Disk Volumes
You can determine the RAID level of a shared disk volume by using the Windows 2000 Disk Management utility to view the volume size.
9-4 User’s Guide
Page 71
If you cannot determine the RAID level using Disk Management, you can use the Dell OpenManage Data Agent Configurator to view the RAID configuration of each volume.
To view the RAID configuration of a volume using Data Agent Configurator, perform the following steps:
1. Start the Dell OpenManage Data Agent Configurator.
2. From the Main Menu, select Devices and then click Scan Devices.
A window appears listing all available disk volumes and their associated RAID levels.
Data Agent Configurator and Disk Management scan the disk volumes in the same order—from top to bottom—so you can map drive letters from Disk Management to the RAID volumes displayed in Data Agent Configurator.

The procedures include the following tasks:
• Adding a network interface controller (NIC) to a cluster node
• Changing the Internet protocol (IP) address of a cluster node
• Uninstalling MSCS
• Replacing cluster nodes
• Running chkdsk /f on a quorum resource
Adding a Third NIC to a Cluster Node
A cluster node should contain a NIC for the following networks:
• Private network—to ensure that each node is connected to the cluster and run-
ning properly
• Public network—to provide connectivity for clients accessing resources on the
cluster
You can also install a third NIC to provide a network connection to additional public network or a separate network for cluster administration
Before you add a third NIC to a cluster node, ensure that the following software is installed on your cluster nodes and configured properly:
• Windows 2000 Datacenter Server with the latest Service Pack
support.dell.com Maintaining the Cluster 9-5
Page 72
• Cluster Service is installed on all cluster nodes.
• NICs in each cluster node are configured properly
See Table 6-2 in “IP Addresses,” in Chapter 6, “Configuring the System Soft­ware,” for a sample IP configuration scheme of Windows 2000 Datacenter Server.
To install a third NIC into a cluster node, you must transfer the resources from the cluster node where the NIC will be installed to another node in the cluster. To properly identify the nodes and NICs, the following procedure refers to specific cluster nodes and components, as described in Table 9-1.
Table 9-1. Cluster Nodes and Component Identification
Cluster Node Description
Node 1 The cluster node where the NIC will be installed.
Node 2 The cluster node you select to temporarily store cluster
resources (such as applications, IP addresses, or storage devices) used in cluster node 1.
NICs 1 and 2 The NICs currently installed in the cluster node for the public
and private networks.
NIC 3 The third NIC you are installing in node 1.
Be sure to refer to Table 9-1 for cluster node identification while performing this procedure.
To add a third NIC to a cluster node, perform the following steps:
1. Prepare NIC 3 for installation.
2. Select a node in your cluster to become node 2, which you are using to temporarily store cluster resources from node 1.
3. Move all cluster resources from node 1 to node 2.
NOTE: See the Microsoft Cluster Service documentation for information on mov­ing cluster resources from one cluster node to another.
4. Power down node 1.
5. Install NIC 3 in node 1.
See the Installation and Troubleshooting Guide for your PowerEdge system for information on installing NICs in your system.
6. In node 1, boot to the Windows 2000 Datacenter Server operating system.
7. On the desktop, right-click My Network Places and double-click Make New Connection.
The Make New Connection wizard starts.
9-6 User’s Guide
Page 73
8. Follow the onscreen instructions to install the NIC 3 driver in node 1.
9. Enter the NIC 3 IP address, ensuring that the network ID portion of the IP address is not identical to NICs 1 and 2.
For example, if NICs 1 and 2 in node 1 have an address of 192.168.1.101 and
192.168.1.102 with subnet masks of 255.255.255.0, respectively, you might enter the following IP address and sub-net mask for NIC 3:
IP Address: 192.168.1.111 Subnet Mask: 255.255.255.0
NOTE: Be sure to use an IP address with the same IP network (the third octet in the IP address) as the first and second NICs.
10. Click OK, exit the Control Panel, and restart node 1.
The Windows 2000 desktop appears.
11. Cl i ck t h e Start button, point to Programs, select Administrative Tools, and then select Cluster Administrator.
12. Click the Network tab and verify that New Cluster Network appears as a new resource.
13. Select the next node in the cluster to become node 2.
14. Move all cluster resources to node 2 (the next cluster node) and repeat steps 4 through 12 on node 1 for the remaining nodes in your cluster.
NOTE: Be sure to assign NICs 1and 2 with the same IP network (the third octet in the IP address) as NIC 3 in node 1. For example you could use 192.168.1.112, thereby continuing the IP address numbering scheme shown in step 9.
If the installation and IP address assignments have been performed correctly, all of the new NIC resources will appear online and respond to ping commands in a Command Prompt window. Additionally, you can also use Cluster Administrator to display the status of the NIC resources.
Changing the IP Address of a Cluster Node
NOTE: To change the IP address of a cluster node, you must stop Cluster Service on the node, reassign the IP address, and then restart Cluster Service.
When a cluster node is down or the Cluster Service is stopped on one of the remain­ing cluster node(s), the Cluster Administrator utility running on one of the remaining node(s) indicates that a cluster node is down by displaying a red icon for the failed node. When the failed node is restarted, the cluster nodes reestablish their connec­tion and the Cluster Administrator changes the failed cluster node icon back to blue to show that the cluster node is back online.

Page 74
Uninstalling Cluster Service
You may need to uninstall the Cluster Service for cluster node maintenance, such as upgrading the node and/or replacing the node. Before you can uninstall MSCS from a node, perform the following steps:
1. Take all resource groups offline or move them to the other node.
2. Stop the Cluster Service running on the node that you want to uninstall.
3. Click the Start button and select Programs—> Control Panel—> Add/Remove Programs.
4. Uninstall the Cluster Service.
5. Start Cluster Administrator from another cluster node.
6. Right-click the node you want to evict and select Options—> Evict Node.
Running chkdsk /f on a Quorum Disk
If your quorum disk is corrupted, you must run the chkdsk command with the /f (fix) option to repair the disk.
Since MSCS uses the quorum resource’s recovery logs to update the cluster data­base, do not run chkdsk /f on the hard-disk drive that contains the quorum resource.
To r u n chkdsk /f on a quorum resource's hard-disk drive, perform the following steps:
1. Move the quorum resource temporarily to another drive by right clicking the clus­ter name, selecting Properties, and then selecting the Quorum tab.
2. Run chkdsk /f on the drive that previously stored the quorum resource.
3. To move the quorum resource, right-click the cluster name, select Properties, and then select the Quorum tab.
4. Select another disk as the quorum disk and press <Enter>.
5. Run chkdsk /f on the drive that previously stored the quorum resource.
6. Upon completion, move the quorum disk back to the original drive.
Replacing a Cluster Node
This section outlines the necessary steps for replacing one of the cluster nodes in your FE100/FL100 Datacenter Server cluster.
NOTE: Before you replace a cluster node, make sure that you performed a tape backup of the cluster node that contains a copy of the local registry. The following steps assume that you have a tape backup of the cluster node.
To replace the cluster node, perform the following steps:
1. Power down and disconnect the failed cluster node.
9-8 User’s Guide
Page 75
2. On the remaining cluster nodes, run Cluster Administrator and evict the failed cluster node by right-clicking the failed node and selecting Evict Node.
3. Make sure that the replacement cluster node is physically disconnected from the PowerVault storage system.
4. Power on the replacement server and install Windows 2000 Datacenter Server, along with the latest Service Pack.
5. Reboot the system.
6. Install and configure the following software and configuration settings:
• NIC drivers
• HBA driver
• IP addresses
See Chapter 6, “Configuring the System Software,“for information on installing the drivers and assigning the correct IP addresses.
7. Install the tape device drivers and backup application program (if applicable).
8. Reinstall the Service Pack, if needed.
9. Reboot the system.
10. Make sure Windows 2000 is configured properly.
11. Shut down Windows 2000 and power down the system.
12. Connect the high-speed serial data connector (HSSDC) cables from each HBA to the PowerVault 65xF and/or 630F storage system either directly or through the PowerVault switches.
See Chapter 4, “Cabling the Cluster Hardware,“for more information on cabling the HBAs.
13. Power on the replacement cluster node. If a backup is not available, install Cluster Administrator and then go to step 15.
14. Using the most current tape backup, restore the cluster node from the tape backup (including the Windows registry files) and restart the system.
15. Use Cluster Administrator to verify that the node rejoins the cluster.
16. Check the Windows Event Viewer to ensure that no errors are encountered.
17. Reinstall all of the application programs (such as Simple Query Language [SQL] Server or Internet Information Server [IIS]) on the new cluster node (if a tape backup is not available).
18. Install any additional service packs or hotfixes.
19. Test the failover capabilities of the cluster resources on the new cluster node.

CHAPTER 10
SAN Components
This chapter provides an overview of a PowerVault storage area network (SAN), addi­tional cluster maintenance procedures, and detailed information on the following storage area network (SAN) components for the Dell PowerEdge Cluster FE100/FL100 Datacenter Server configuration:
• SAN-attached clusters
• PowerVault Fibre Channel switches
• PowerVault storage systems attached to a SAN-attached cluster
Overview of a PowerVault SAN
A PowerVault SAN is a configuration of server and storage systems that incorporates dedicated Fibre Channel connections between the server and storage systems. A SAN bypasses traditional network bottlenecks and supports direct high-speed data transfer between the servers and storage devices. SAN storage may consist of both hard-disk drive and tape storage devices that are connected through switches and bridges to one or more servers or clusters.
NOTES: See the Dell PowerVault SAN documentation for more information.
A PowerEdge Cluster FE100/FL100 Datacenter Server configuration cannot coexist on the Fibre Channel switch fabric with other clusters or stand-alone servers.
PowerVault SAN Components for PowerEdge Cluster FE100/FL100 Datacenter Server Configurations
Dell PowerVault SAN products supported in PowerEdge Cluster FE100/FL100 Datacenter Server configurations include the following components:
• PowerVault 650F and 651F - Fibre Channel storage systems
• PowerVault 51F and 56F - Fibre Channel switches
• QLogic QLA-2200/66 - Fibre Channel host bus adapters (HBA)
• PowerVault 35F - Fibre Channel-to-small computer system interface (SCSI) bridge
• PowerVault 130T - Digital Linear Tape (DLT) library

Page 78
NOTE: See the Dell PowerVault SAN documentation and the appropriate SAN compo­nent documentation for configuration information.
SAN-Attached Clusters
SAN attached clusters are cluster configurations where redundant Fibre Channel HBAs are cabled to a redundant Fibre Channel switch fabric. Connecting the cluster to the storage system is achieved through the switch fabric. These SAN-attached config­urations can share certain resources with other servers, storage systems, and backup systems on the SAN.
In a SAN-attached cluster configuration, all of the cluster nodes are attached to a sin­gle PowerVault storage system or to multiple PowerVault storage systems through a PowerVault SAN using a redundant Fibre Channel switch fabric. One or more PowerVault Fibre Channel switches make up a Fibre Channel switch fabric.
Figure 10-1 shows an advanced SAN-attached cluster configuration using four-node clustering.

Fibre Channel Fabrics
A Fibre Channel switch fabric is an active, intelligent, and private connection of one or more fibre channel switches that provide high-speed, point-to-point connections between servers and storage devices. Using instructions that are programmed into the switch, the switches in a Fibre Channel fabric provide a point-to-point connection through inbound and outbound points from one device (sender) to another device or switch (receiver) on the network. If the data is sent to another switch, the process repeats itself until a connection is established between the sender and the receiver.
Fibre Channel switches are linked together using interswitched links (ISL). These ISLs use two high-speed serial data connectors (HSSDC) or two subscriber connectors (SC) to connect the switches. Each ISL is considered a “hop.” While a Fibre Channel
support.dell.com SAN Components 10-3
Page 80
switch fabric can support up to seven hops without performance degradation, a typi­cal PowerVault SAN implementation usually includes fewer than seven hops.
Attaching a SAN-Attached Cluster Configuration to a Network
SAN-attached clusters are cluster configurations where redundant Fibre Channel HBAs are cabled to a redundant Fibre Channel switch fabric. Connecting the cluster to the storage system is achieved through the switch fabric. These SAN-attached config­urations can share certain resources with other servers, storage systems, and backup systems on the SAN.
SAN-attached cluster configurations can be attached to the following types of networks:
• Public network - A network that connects the cluster nodes to the client network.
This network consists of devices such as Ethernet network interface controllers (NIC) installed in the cluster nodes.
• Private network (node-to-node cluster interconnect) - A dedicated network that
connects the servers to each other. The primary function of the private network in a cluster configuration is to pass heartbeat information that allows each cluster node to monitor the health of the other cluster node.
• Storage area network (SAN) - A configuration of computer and storage systems
that incorporates dedicated Fibre Channel connectivity between the computer systems and storage. A SAN bypasses traditional network bottlenecks and sup­ports direct high-speed data transfer between the servers and storage devices.
NOTE: Each segment may vary in components and complexity.

Using Dell PowerVault Fibre Channel Switches
You can connect cluster nodes to the PowerVault shared storage system by using redundant PowerVault Fibre Channel switches. When cluster nodes are connected to the storage system through Fibre Channel switches, the cluster configuration is tech­nically attached to a SAN.
To connect your cluster nodes to the PowerVault shared storage system, your system must have the following hardware components:
• Two PowerVault 51F or 56F Fibre Channel switches (more switches may be nec-
essary depending on the configuration)
• Copper high-speed serial data connector (HSSDC) or fibre optic cables to connect
the cluster nodes to the Fibre Channel switches
• Copper cables with an HSSDC connector on one end and a DB-9 connector on
the other to connect the Fibre Channel switch to the PowerVault storage systems
Attaching a PowerVault Storage System to a SAN-Attached Cluster
The following sections provide configuration and cabling examples for attaching a PowerVault storage system to a SAN-attached cluster.
Connecting the PowerEdge Cluster to a Single PowerVault Storage System
You can add fast and reliable data redundancy to your cluster configuration by adding a PowerVault storage system. This configuration allows you to share the SAN with other clusters and servers, thereby adding scalability to your cluster configuration.
To attach a PowerVault storage system to your cluster, connect each cluster node to both Fibre Channel switches and connect each Fibre Channel switch to the PowerVault storage processors on the cluster's shared storage.
An example of a PowerVault storage system attached to a PowerEdge cluster is shown in Figure 10-2.
10-6 User’s Guide
Page 83
Connecting a PowerVault 130T DLT Library and PowerVault 35F Fibre Channel Bridge to a Cluster­Attached PowerVault SAN
You can add tape backup devices to your PowerVault SAN to provide additional backup to your cluster. To implement this configuration, use the PowerVault 35F Fibre Chan­nel SCSI bridge to support the PowerVault 130T DLT library on PowerEdge Cluster FE100 Datacenter Server configurations.
Figure 10-2 shows a supported PowerEdge Cluster FE100/FL100 Datacenter configu­ration using redundant Fibre Channel switches, Fibre Channel bridge, and PowerVault 130T DLT library. In this configuration, each of the cluster nodes is attached to the backup device and the backup local disk resources, as well as to the owned cluster disk resources. Using this configuration provides you the ability to add more servers and storage systems in the future, if needed.
NOTES: See the storage and tape backup documentation for more information on configuring these components.
Contact the tape backup software vendor for more information on using your software in a cluster configuration.
The PowerVault 35F Fibre Channel SCSI bridge, the PowerVault 130T DLT library, and their cables are made through a single switch fabric and do not comprise a redundant configuration. Therefore, tape backups may be incomplete if one of these compo­nents fails.
Configuring Hard-Disk Drive Letters Using Multiple Shared Storage Units
Before installing the Cluster Service, ensure that both nodes have the same view of the shared storage. Because each node has access to hard-disks that are in a com­mon storage array, each node must be assigned identical hard-disk drive letters.
To ensure that the hard-disk drive letter assignments for the cluster nodes, perform the following procedures:
1. Ensure that your cables are connected properly.
The Windows 2000 Disk Management utility displays all of the accessible disks attached to the first QLogic HBA, followed by those that are accessible from the second QLogic HBA.
On the first HBA, the attached disks will be displayed numerically, starting with the lowest port number.
2. Ensure that the first QLogic HBA detected by each cluster node is connected to the switch attached to PowerVault storage processor A.
3. Ensure that the second QLogic HBA detected by each cluster node is connected to the switch attached to the PowerVault storage processor B.
support.dell.com SAN Components 10-7
Page 84
4. Assign drive letters and volume labels to the disks.
To assign drive letters and volume labels to the disks, perform the following steps:
a. Power down all cluster nodes except node 1.
b. Assign drive letters on node 1, using the Windows 2000 Disk Management
utility to create the drive letters and volume labels.
For example, create volumes labeled “Volume E” for disk E and “Volume F” for disk F.
c. Power down the cluster node.
d. Power on the next cluster node and start the Windows 2000 Disk
Management utility. Assign the drive letters to the shared disks and shut­down the node.
e. Repeat step d for each remaining node.
The drive letter assignment should be performed on each of the shared disks, even if the disk displays the drive letter correctly.
If the cables are connected properly, the drive order will be the same on all nodes, and the drive letter assignments should follow the same order on all nodes.
The volume labels can also be used to double-check the drive order by ensuring that the disk volume label is assigned to an identical drive letter for each node.
