Verifying Creation of the Cluster

Now that the software is installed, use the following steps to verify the
creation of the cluster.

1. Shut down and power down both server nodes.

2. Power down and then power up the shared storage area.

3. Power up both server nodes.

When Windows NT finishes booting up on both server nodes, follow these
steps to use Microsoft Cl uster Administrator to verify creation of the cluster:

1. From the desktop on either server node, select Start, Programs,

Administrat ive Tools (Common), Cluster Administrator.

2. When prompted for the cluster or server name, enter the name or IP

address of one of the ser ver node s.

System Setup and Confi guration for Microsoft Windows NT S/E 4.0 1-9

3. If the cluster has been created correctly, the names of both server nodes

appear on the left side of the Cluster Administr ator window ( s ee Figure
1-1). Note t he cluster name.

Figure 1-1. Microsoft Cluster Administrator

Verifying Server Node Failover

NOTE: When running the failover test, start with the least complex test. Do not run any

client activity while testing failover events.

Follow these steps to verify failover of a server node:

1. From the desktop on both server nodes, select Start, Programs,

Administrat ive Tools (Common), Cluster Administrator.

2. When prompted for the cluster or server name, enter the name or IP

address of one of the ser ver node s.

3. Make sure all pre defined resou rces and gr oups are online. Verify that

some of the resources and groups are owned by the server node you are
powering down so that a failure event will result in failover of resources
and groups.

1-10 Compaq ProLiant CL1850 Software User Guide

4. Power down one of the server nodes.

5. Within several seconds, Cluster Administrator running on the surviving

server node should bri ng online all of the predefined resources and
groups tha t were previously owned by the powered-down server node.
If, after a minute, not hing appear s to have happened, ref resh the screen
by selecting Ref re sh (F5).

Verifying Network Client Failover

Now that you have verified that each server node is running correctly as a part
of the cluster, the next st ep is to verify that net work client s can interact with
the cluster.

The following steps will lead you t hrough this validatio n procedure.

1. Ensure both server nodes are running, and verify, using Cluster

Administra tor, that all groups and resources are online.

2. For each hard drive in the shared storage, Cluster Server automatically

creates a cluster group that consists of a single resource, the hard drive.
Using Cluster Administ rator, add an existing IP address as another
resource to one of these gr oups. (DO NOT use the Cluster Group.) Sa ve
the changes and return to the mai n Cluster Administrator screen.

3. Open a DOS window on a networ k client machine.

4. Ensure the network client can access the IP address, added in Step 2.

From the network client, execute a PING command, using the cluster IP
address as the argument.

NOTE: Regardless of whether you are using WINS or DHCP, you can execute the DOS
command “PING” to check the connection.

The client has successfully accessed the cluster resource if you get a

response similar to:

Reply from <IP Address>: bytes=xx time=xxxms TTL=xx.

The client has not successfully accessed the cluster resource if you get a

response of:

Reply from <IP Address>: Destination host unreachable

5. Following the completi on of the PING command, use Cluster

Administrator to perform a manual failover of the cluster group that
contains the IP address.

6. After the manual failover completes, execute the PING command again.

System Setup and Confi guration for Microsoft Windows NT S/E 4.0 1-11

7. As soo n as the other server node brings the cluster gro up online, a

response simi l ar to the one noted in Step 4 should be returned. If the
client successfully accessed the failed over IP address, your cluster is
working. If the client wa s unsuccessful, either t he cluster gr oup was not
configure d correctly, the failover did not occ ur, or the PING command
was performed before the failover activity completed.

NOTE: To verify a more extreme case, rather than fail over the IP address, power down
the primary cluster server node and verify that the resource fails over to the other server
node.

Setting Up Cluster Groups and Cluster
Resources

You have now set up and c onfigure d all your clustering hardware. Microsoft
Windows NT Server 4.0, Ent erprise Edi t ion and Cluster Server are installed on
both server s. You have done some minimal validation of your cluster a nd
everything is working as planned. Now it is time to set up your applicat ions to
utilize the capabilities of clustering.

If you have defined your cluster needs correc tly and deter mined how t o fit
your applications and environment into a cluster, conf iguring y our applications
will be a straightforward task.

Although details of these procedures are beyond the scope of this guide,
several documents are available f rom both Mic rosoft and Compaq to a s sist
you with thes e final steps.

The best source of information concerning the steps to configure cluster
groups and c luster res ources is Micr osoft’s Cluster Server Administrato r’s

System Setup and Configuration for Novell NetWare 2-5

Configuring the Cluster for NetWare 4.2

Novell High Availability Server (NHAS) is the software needed to run the
clusterin g aspect of the ProLiant CL1850 when running NetWare 4.2. T his
software must be installed after each server node has NetWare 4.2 loaded and
at least one volume from the shared storage array has been mounted to each
server node. NHAS will allow you to accomplish the following:

■ Configure the cluster

■ Pause the cluster

■ Manual failover

■ Manual failback

■ Automatic failover

■ Automatic failback

For instructions on NHAS installation and detailed use of these functions,
please refer to the

Novell High Availability Server User’s Guide from Novell.

Preparations for Installing NHAS

The following is a list of preparations needed prior to installation of NHAS.

■ Check network connections to and from each server using Display

Servers command at NetWare console.

■ Use the Config command to check all IP addresses and to make sure

there is a network connection bo unded to the IPX protocol for the D i rect
Link. Label this network port as such for simpl icity in re cognition
during the NHAS installation. A second network connection should
exist for public NetWare Link.

■ Be sure to allocate and mount at leas t one shared volume for each server

by using the Volume Options in the Install utilit y. Multiple volumes will
imply the same rule. Try to gauge which applications will be installed so
the volumes’ File Compression and Block Subal location se ttings are
appropriate. Otherwise, you will need to reinstall NHAS later.

■ Each server in the cluster must have an internal hard drive that is not

part of the shared subsystem. A SYS: volume on the shared subsystem
would be confusing a nd potential ly damaging.

2-6 Compaq ProLiant CL1850 Software User Guide

■

NetWare volumes can span multiple drives. When a volume spans more
than one drive, all of the drives that it spans must be shared or all of
them must be not shared. Otherwise if one drive fails, there will be no
access to the volume from either cluster server.

■ NHAS cluster server will function within different containers in the

NDS tree, but they must reside in the same directory tree to ensure
smoother failover of NDS resource objects.

■ It is not necessary for servers in the cluster to contain NDS replicas as

long as multiple trusted replica s exist on the network. If one server i n
the cluster contains a trusted NDS replica, then for NDS availability
reasons, both servers should contai n a replica.

NOTE: You must install the latest NetWare Support Pack and then the NSSD before
installing NHAS.

Installation of NHAS

NHAS is installed by mounting the NHAS CD on a server and using the
CD-Mount H A command, then entering the following on the console.

LOAD HA:HASERVER/HASINST

When prompted to selec t the other se rver node of the cluster pair, enter the
“V” command at the NetWare console of the other server node. From t he first
server node, you will then select the Direct Link. When the file copy is
complete, finish the installation by pressing Enter, Down, Exit, and Restart
both servers.

System Setup and Configuration for Novell NetWare 2-7

Verifying Functionality of the Cluster

Now that the software is installed, you can verify the creation of the cluster
from the NHAS Console. All three links under Connection Status will show
Connected. See Figure 2-1.

Figure 2-1. NHAS: Connected

Verifying Direct and NetWare Links

To test Direct Link Disconnect:

1. Remove the network cable from the server’s network car d to which

Direct Link is dedicated. The Direct Link status on the NHAS screen
should change from Co nnected to Not Connected.

2. Reconnect the network cable to the network card. The Direct Link status

should change from Not Connected to Connected.

2-8 Compaq ProLiant CL1850 Software User Guide

To test NetWare Link Disconnect:

1. Remove the network cable from the server’s network car d to which

NetWare Link is dedicated. The NetWare Link status should change
from Connected to Not Connected.

2. Reconnect the network cable to the network card. The NetWare Link

status should change from Not Connected to Connected.

Verifying Server Node Failover

When running the failover test, it is recommended to star t with the least
complex test, so do not run any client activity while testing failover events.
For instructions on testing NHAS Failover, please refer to the NHAS user’s
guide from Novell.

Configuring the Cluster for NetWare 5

Do the following prepar ations bef ore installation.

1. Install all necessary Support Packs and NSSDs.

2. Ten MB of free space that is not part of an NSS or DDFS partition on

the shared storage array is required for the split brain partition. Be sure
this partition can be readily seen through both server n odes.

3. If you want to zone the intra-c l uster links and separate it from the ma i n

public network link, be sure to assi gn it an IP addr ess of a different
subnet on a NIC through NetWare. You will have the optio n t o choose
the specific NIC during NCS installation.

The Novell Cluster Services Installation creates a new cluster object and
installs Novell Cluster Services s oftware on the server nodes you specify to be
part of your cluster. This installation is done from a remote client workstation
machine.

1. Insert the NCS CD into the CD- ROM drive on the client workstation

with administration rights to the directory tree to which the server nodes
reside.

2. From the initial splash screen, lau nch the Novell Cluster Services

installation. Continue throug h the installation screens until you get to the
screen that prompts you to create a new cluster.

3. Select Create a New Cluster. Then click Next.

4. Enter a name for the new cluster object y ou are creating and specify the

directory tree and context where you want it created. Then click Next.

System Setup and Configuration for Novell NetWare 2-9

5. Enter t he name of the server nod e you want to add to the cluster, or

browse and select one from the list, and then click Add to Cluster.
Repeat this step for the second server node to add to the cluster. When
you add a server node to a c luster, Novell Cluster Se rvices automatically
detects the server node’s IP address. If the server node you are adding
has more than one IP addre ss, you will be prompted t o select the IP
address you want Novell Cluster Service s to use.

6. Specify that your cluster has a shared disk system, then select the drive

where you want the small cluster partition created. Novell Cluster
Services requires a small cluster partition on the shared disk system.
You are also given the option of mirroring the partiti on for greate r fault
tolerance.

IMPORTANT: You must have a small amount of free space on one of the shared disk
drives to create the cluster partition. If no free space is available, the shared disk drives
will be unusable by Novell Cluster Services.

7. Continue through the final installation screen. The Novell Cluster

Services installation program will then create a new cluster for you and
add the server nodes you specified in the install to the cluster.

After creating a new cluster, you now need to create cluster resources and
configure those resour ces. You also should consider adding NetWar e volumes
to the cluster and creating cluster resource templates.

Verifying NCS Cluster Creation

Create a simple application cluster resource object via a “load monitor.” Be
sure to add the server nodes to the resource so the resources can startup. Start
up the resource and force a migration. On the local server console screens you
should be able to see the monitor utility load and unload.

Create a simple volume object (note you will need to create a NSS volume
from NetWare first). Be sure to add the server nodes to the resource so the
resources can startup. Start up the resource and force a migration. On the local
server console screens you should be able to see the monitor utility load a nd
unload.

Adding Physical Drives

The system’s CR3500 RAID Controllers must recognize the physical drives in
the shared storage area before you can create logical drives from them. The
controller will recognize all physical drives at start up. To add physical drives
to your configuration after the controller has st arted, follow these ste ps:

IMPORTANT: Before adding physical drives that have previously been used by another
ProLiant CL1850, it is necessary to delete any configuration settings on the drives. Failure
to do so can cause conflicting RAID settings on the CR3500 controller.

1. Physically add the drives to the system.

2. Run the CR3500 Configuration Utility to configure the drives.

NOTE: You cannot increase the capacity of an existing logical drive.

CR3500 Configuration Utility 3-19

3. From the Main window, click Physical Drive, then click New.

4. The Add New Physical Drive Window appears. Enter the channel

number and Target ID for the new physical drive. The Target ID is
displayed o n the gr id.

NOTE: An alternate method for adding drives is to click on an empty cell in the grid, then
right click and select New. This presents the Add New Physical Drive window with the
channel number and target ID currently assigned.

5. Click the OK button. The program adds your physical dr ive to your

Replacing a Failed Controller

Replacing a Failed Controller in a Single
Controller Environment

1. Power down the shared storage array.

2. Remove the failed controller.

3. Insert the new controller.

4. Restore the configuration settings. See the section “Restoring

Configuration Setting from a File” for this procedure.

CR3500 Configuration Utility 3-25

Replacing a Failed Controller in a Redundant
Controller Environment

A failed co nt roller can be replaced without powering down the share d storage
array. To replace a failed controller:

1. Remove the failed controller.

2. Insert the new controller.

Replacing a Failed Drive

A failed drive can be replaced without powering down the shared storage
array. When a drive fai ls, two things can happen:

■ The logical drive associated with the failed drive utilizes a spare and

rebuilds the spare drive to join the logical drive. The logical drive will
be in a reconstructing state.

■ The logical drive stays in a reduced state until a new drive is added.

To replace the failed drive:

1. Remove the failed drive.

2. Insert the new drive.

3. See the “Adding Physical Drives” section for procedures to make the

new drive k nown.

4. Set the new drive status.
If a spare drive was used to reconstruct the affected logical drive, set the

new drive as a spare drive.

If there was no spare drive to use, the logical drive is still in a reduced

state. Add the new physical drive to the logical drive and reconstruction
can start.

a. Select the logical drive in reduced status.
b. Select Logical Drive from the Storage pull down menu.
c. Select Reconstruct.
d. A list appears showing you available drives. Select the drive you just

added.

e. Reconstruction begins.

3-26 Compaq ProLiant CL1850 Software User Guide

Setting a Physical Drive as a Spare

NOTE: Spare drives serve as spares to all logical drives. They are not grouped with a

particular logical drive.

How a Spare Works

■ If a physical drive fails in a RAID 1, RAID 0+1, RAID 4, or RAID 5

logical drive, the spare automatically replaces the failed physical drive
and the controller reconstructs all logical drives the failed physical drive
was a member of.

■ Once the controller writes data to a spare, the spare becomes part of the

same device group in whi ch a device failed.

■ Once the controller writes data to a spare, the status of the spare changes

to Good.

To Define a Spare Physical Drive

1. In the main window, click the physical drive to be used as a spare. The

physical drive must be in the Available state.

2. From the Storage menu, choose Physical Drive, then choose Make

Spare.

NOTE: The spare must have a capacity equal to or greater than the failed physical drive
for an automatic reconstruct to start.

Managing Spare Physical Drives

Making a spare physical drive part of a logical drive will protect the integrity
of the RAID setup. This proves especially true for logical drives that have
RAID requirements of two or more physical drives. Sh ould one physical drive
fail, the logical drive will automatically activate the spare physical drive as an
instant replacement for the failed one.

Managing Failed Physical Drives

To return a failed physical drive to a nonfailed state, from the Storage menu,
select Physical Drive, and then select Clear Failure.

You can easily identify a failed physical drive from the main screen because
the failed icon will appear. See Table 3-5 for the physical drive icons.

CR3500 Configuration Utility 3-27

Deleting Logical Drives

CAUTION: If you delete a logical drive, all of your data on that logical drive will

be lost. The logical drives in your storage subsystem are logical units that
contain your user data. Although they do not exist in a physical sense, it is their
logical structure that ties together the physical pieces of your data spread
across their members. Use extreme caution when deleting a logical drive.

1. Click t he logical drives that you want t o delete.

2. From the Storage pull-down menu, select Logical Drive, then select

Delete. A system message a ppears, asking if you wa nt to delete all disks
in the group.

3. Click Yes to delete all the disks in the group.

Using Configuration Files

You can use a configuration file to save the conf iguration settings of t he
CR3500 RAID Controllers and disk drives and vi ew or reconstruct the settings
at a later time. You also can revert to one of these saved configurations at any
time. The CR3500 Configuration Utility read s the configuration file you
choose and se t s up your su bsystem accordingly.

Saving Configuration Settings to a File

From the Storage pull-down menu, select Controller, then select
Configuration, then select Save. The current c onfiguration settings, i ncluding
caches, LUNs, host ports, and strip size will be saved.

CAUTION: When saving a configuration, all controller data and RAID set data is
preserved at the time of the Save operation. When restoring a configuration, the
configuration being restored must match EXACTLY the configuration when it
was saved. Any RAID sets in existence when the Restore Configuration operation
takes place that were not in existence when the configuration was saved will be
reinitialized, and any data on those RAID sets will be lost. Make sure you have a
recent backup copy of your configuration data before you execute this operation.

Restoring Configuration Settings from a File

You can automatically restore or configure your entire storage subsystem from
a previously saved configuration file. The CR3500 Configurati on Utility can
configure your subsystem from a file only if t he file corresponds to your
subsystem’s har d wa re confi g ur ati on.

3-28 Compaq ProLiant CL1850 Software User Guide

From the Storage pull-down menu, select Controller, then select
Configuration, then select Restore .

All of the configurati on settings, i ncluding caches, LUNs, host port, and strip
size will be restored to their original condition.

CAUTION: When restoring a configuration, the configuration being restored
must match EXACTLY the configuration as it was saved. Any RAID sets in
existence when the Restore Configuration operation takes place that were not in
existence when the configuration was saved will be reinitialized, and any data
on those RAID sets will be lost.

You will not be able to restore the original configuration settings if the original
hardware and connections have been replaced or if the original configuration
settings were not saved before implementing the changes.

Updating Firmware

At some time, new firmware may be released for the CR3500 RAID
Controller. This firmware can be obtained from the Compaq website. To
update the firmware on the controller, select Update Firmware from the
Storage pull–down menu from the main screen. Enter the new firmware file
location and click Update.

IMPORTANT: Microsoft Cluster Server service, SNMP service, and any I/O must be
stopped during the firmware update.

Upgrading from a Single Controller
to Redundant Controllers

To upgrade your system from a single CR3500 RAID Controller to a
redundant CR3500 RAID Controlle r configuration, follow these steps.

1. Save the existing single controll er configuration usi ng the Save

Configurat ion function.

2. Suspend all I/O and power down the shared storage subsystem.

CR3500 Configuration Utility 3-29

3. Install the redundant contr ol ler in the bottom controller slot of the

shared storage subsystem.

4. Power up the shared storage subsystem.

5. Restore the controller configuration settings that you saved in Step 1.

NOTE: If restoring configuration settings using a serial connection, both controllers must
be attached to the host machine.

Error and Warning Messages

When you start the CR35 00 Configuration Utili ty, the softw are checks each
controller to detect e rrors in its configuration. If a problem is found, the
CR3500 Configuration Utility displays an error warning message that
describes the problem.

IMPORTANT: If a warning message indicates “Internal Error Has Been Detected” and
cites an error code number, the problem requires assistance from Compaq technical
support. See the “About This Guide” section at the beginning of this book for technical
support phone numbers.

Refer to the Online Help for more information.

Integrated Management Log

NOTE: The Compaq Integrated Management Log (IML) only records events for the server

nodes. The IML does not record events in the shared storage array.

The Compaq Integrated Management Log (IML) records events and stores
them in an easily viewable form. The Compaq Integrated Management Log
records hundreds of events and then marks each e vent with a time-stamp with
one-minute granularity.

Events listed in the Compaq Integrated Management Log are categorized as
one of four event severity levels:

■ Status–indicates that the message is informational only.

■ Repaired–indicates that corrective action has been taken.

■ Caution–indicates a nonfatal error condition.

■ Critical–indicates a component failure.

The Compaq Integrated Management Log requires Compaq Operating
System-dependent drivers. Refer to the Compaq SmartStart and Support
Software CD for instructions on insta l ling the appropriate dr i vers.

4-2 Compaq ProLiant CL1850 Software User Guide

Throughout the life of your Compaq ProLiant CL1850 you will encounter the
need to improve performance, upgrade hardware components, upgrade
software, increase storage capacity, restructure cluster groups, back up cluster
data, or merely monitor ongoing activities. This chapter describes the se
management concepts a s t hey pertain to Microsoft Cluster Ser ve r (MSCS)
clusters. The chapter also details the utilities and programs used in the ongoing
management of your system. The topics addressed in this c hapter incl ude:

■ Cluster Management Conce pts

■ Microsoft Clust er Administrator

■ Modifying Physic al Cluster Resources

■ Backing Up Your Cluster

■ Managing Cluster Performance

5-2 Compaq ProLiant CL1850 Software User Guide

Cluster Manageme n t Conce p ts Usi ng
Microsoft Windows NT

Managing a Cluster without Interrupting
Applications or Services

At some time during the life of your system, it is likely you will need to
perform an operation on a server node that will require it to be powered down.
Always use Cluster Administrator to fail over (or at a minimum, bring offline)
clustered a pplications before powe ring dow n t he server.

Managing a Cluster in a Degraded Condition

Due to the high-availability nature of clustering, applications and network
clients remain operational even while some cluster components do not. When
the cluster is in this degraded condition, it is important to fo llow this process:

1. Under s tand what caused the de gradatio n.

2. Determine whether the condition will conti nually worsen.

3. Determine how critical it is to repair the problem.
a. If the problem is considered noncritical, wait until a nonpeak time to

service the problem.

b. If the problem is considered critical, fail over all cl ustered

applications and resources to the other server node before servicing
the proble m.

Managing Hardware Components of Individual
Server Nodes

Compaq Insight Manager has been enhanced to operate with the Compaq
ProLiant CL1850. While Compaq Insight Manager maintains its current
features of viewing and managing servers and their components, it now allows
you to view t wo server nodes as a single cluster e nt ity. A comprehensive
overview of Compaq Insight Manager’s cluster capabilities appears later in
this chapter.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-3

Managing Network Clients Connected to a Cluster

An important aspect of m anaging network clients is to inform the users that
their applications are now running on a cluster. Since users will experience
some disruption of service, and possibly a performance degradation during
failover, they might become concerned about the availability and stability of
their applications. As the cluster is initially brought into a production
environment, it might be beneficial to describe in a memorandum the effects a
cluster will have on the users ’ information systems needs.

When a failover or failback event occurs, the users’ perspective will be only
that they cannot access their application or data. When users have been
properly forewarned of the effects of operating in a clustered environment,
they will more readily recognize when a failover or failback event is occurring
or has occurred. Most will wait several minutes before trying to reconnect to
their application or data.

Managing a Cluster’s Shared Storage

Compaq Insight Manager monitors the cluster. The physical drives and
hardware are monitored via the Mass Storage Overview screen, accessed from
the Device View screen.

The shared logical drives (as well as other cluster resources and services) are
monitore d vi a the Cluster Management and Cluster Shared Re sources scr eens,
accessed from a cluster folder in the Device List.

Because this storage system is shared, either server node could be the owner of
any shared logical drive. While only one server node can own the logical drive
at any given time, ownership can sw itch from one server node to another.
Compaq Insight Manager reports the current owner of a logic al drive and
updates this informat ion dynamically if a failover occurs.

NOTE: Compaq Insight Manager shows the shared logical drives as cluster resources
owned by a particular server node. It shows the cluster hardware as a physical resource
of both servers in the cluster.

When viewing the Compa q Insight Manager Cluster Shared Resources screen,
you can dete rmine which logical drive contains a parti cular dri ve by looking at
the Physical ID field under the Shared Resources heading.

5-4 Compaq ProLiant CL1850 Software User Guide

Remotely Managing a Cluster

Both Compaq Insight Manager and Mic rosoft Clust er Administ rator can be
run from network client machines . Each pr ogram allows monitoring of
multiple clusters from a single remote client. See the corresponding
documentation to determine how to set up and configure each of these
programs to run remotely.

Cluster Events

Cluster events are logged in the Windows NT Event Log. Use the
Windows NT Event Viewer to view the data in the Event Log.

Cluster Management Screen

Compaq Insight Manager includes a Cluster Management scree n. From the
Cluster Management screen you can:

■ Launch Microsoft Cluster Administrator

■ Bring up the Compaq Insight Manager Cluster Shared Res ources screen

■ View the status of the cluster service running on each server node

■ View the overall status of all cluster resources. This information is

updated dynamically.

You can launch the Cluster Management screen (Figure 5-3) by using any of
the following methods:

■ Select from the Task List or right-mouse menu of a clustered device.

■ Select from the right-mouse menu of the Cluster Software item.

■ Double-click on the Cluster Software item.

Figure 5-3. Cluster Management screen

If Microsoft Cluster Administrator is installed on the Compaq Insight Manager
console, you can launch Cluster Administrat or by clicking on the Cluster
Administrator button near the upper-right corner of the screen, or by selecting
an option from the right-mouse menu of the Cluster Software item. Cluster
Administrator will launch directly to the cluster represented by the Cluster
Manageme nt screen.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-7

Cluster Shared Resources Screen

The Cluster Shared Resources screen (Figure 5-4) contains specific
information about the cluster interconnect and all cluster resources running on
the server node.

From the Com paq Insight Manager Cluster Shared Resources screen you can:

■ View address, transport protocol, and physical ID of all cluste r

interconnects

■ View the current state of all cluster resources

■ Sort the interconnect information and resources by multiple criteria

Figure 5-4. Cluster Shared Resources screen

All displayed interconnect and resource information is polled and updated
dynamically, including status and ownership.

For example, assume two drive volumes are defined in your shared storage.
The primar y owner of the drive volume labeled E: is server node 1. The
primary ow ner of the drive volume labeled F: is server node 2. When the
cluster is in a normal state, Insight Manager will show E: as being owned by
server node 1, and F: as being owned by server node 2. When a failover eve nt
occurs, ownership of t he drives changes. Assume server n ode 1 experiences a
failure and its resources fail over to server node 2. When the failover is
complete a nd Insight Manager polls the clust er, server node 2 will be
identified as the owner of both F: a nd E:.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-9

Filter Groups Dialog Box

The Filter Groups dialog box (Figure 5-6) is used to create, edit, or delete
groups in the group list hierarch y.

Follow these steps to launch the Filter Groups dia log:

1. From the G roup window in the Dev i ce List window , select the group

you want t o work with. (For exampl e, if you want to create a group
within Network, select Network.)

2. Select the Set Up Group button on the control bar.

Figure 5-6. Filter Groups dialog box

The Insert cluster shortcut button allows you to create shortcuts for existing
cluster groups and place them in different levels in the group hierarchy.

Cluster Address

A cluster address acts as a proxy, communicating with different servers in the
cluster depending on the state of the cluster. A Compaq Insight Mana ger
device using a cluster address may switch communication from one physical
device to another, whi ch may result in erroneous inform ation being delivered.
Consequen tly, Compaq Insight Manager does not allow management of a
device that uses a known cluster address.

5-10 Compaq ProLiant CL1850 Software User Guide

Microsoft Cluster Administrato r

While the primary res ponsibility of Compaq Insight Manager is to monitor the
overall status of the cl uster hardware, services , and resources, Microsoft’s
Cluster Administrator is most ade pt at managing the groups , resources, and
operating state of the cluster. Cluster Administr ator gives you the ability to:

■ View the current st atus of cl uster groups and resources

■ Bring groups an d resources online and of fline

■ Manually move groups and re sources t o another ser ver node

■ Manually move groups and resources t o their preferred server

■ Pause groups and re sources

■ Restructure a group’s resource dependency tree

Cluster Administrator can be run remotely or on a server node. If Cluster
Administrator is installed remotely, the remote node must be i n t he same
domain as t he server node . When run ni ng Cluster A dministrat or remotely, you
should connect to the cl uster via Compaq Insig ht Manager or by using the
cluster IP address or cl ust er name.

NOTE: The remote feature is not supported in Microsoft Windows 95/98.

Refer to the Microsoft Cluster Server Administrator’s Guide for a thorough
descripti on of Cluster Administrator’s features and specifics on how to use the
utility.

Modifying Physical Cluster Resources

Removing Shared Storage

Each server node, and the cluster as a whole, depends on the shared storage for
data, log, and, possibly, application program files. If the s hared storage is
removed, all clustered applications that are dependent on that shared storage
system will be offline. Clearly, network clients will not have access to the
clustered applications.

Before removing a shared storage system (that is, the cluster), use Cluster
Administrator to bring offline all c luster groups and resources on both server
nodes. This ensures the groups and resources are gracefully brought offline,
rather tha n causing an abrupt interruption of service by pow ering down the
cluster.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-11

Adding Shared Storage

A ProLiant storage syste m cannot be added while the cluster is running.
Follow these steps to add another shared storage system to an existing cluster.

1. Use Mic rosoft Clus t er Adminis trator to bring all cluster groups and

resources offline.

2. When i nst alling the new storage system, you do not want the cluster

service to start automatically. On each server node, go into the
Windows NT Services Control Panel a pplet and set the cluster service to
Manual.

3. Shut down and power off both server nodes an d the shared storage

array.

4. Plug all of the SCSI drives into the shared storage array.

5. Power u p the newly a dded storage system and the CL1850 shared

storage array.

6. Power up server node 1 and run the CR35 00 Co nfiguration Utility. Set

up the logical drives.

IMPORTANT: Be sure you understand your cluster groupings of applications and
resources whose data, log, and program files may reside on these drives. See Chapter 4
for information on creating cluster group.

7. Run Disk Administra tor to assign permanent letters to the drive

volumes.

8. Shut down the server node 1.

9. Power u p the server node 2.

IMPORTANT: Do not run the CR3500 Configuration Utility on the second server node. The
information entered from the first server node is maintained on the drives; therefore, the
drives are already configured for the second server node.

10. Boot Windows NT on server node 2, then run Disk Administrator.

Verify that the drive letters displayed are the same as those assigned
from the first server node.

11. Power on server node 1 and allow it to boot into Windows NT. Go into

the Service Control Panel applet and start the cluster service. Start
Cluster Administrator and verify that the added drives ar e visible as
unassigned physical disk resources.

5-12 Compaq ProLiant CL1850 Software User Guide

12. On server node 2, go into the Service Control Panel applet and st art the

cluster service. Start Cluster Administrator and verify that the added
drives are visible as unassigned physical disk resources.

13. On the server node 1, create the groups or resources that use the new

physical disk resources.

14. Ensure that all applications and resources are still offline on both server

nodes. If not , take them offline.

15. On each server node, go into the Service Control Panel applet and set

the cluster service to start automatically.

16. Shut down and power down both server nodes.

17. Wait several seconds, then power up both server nodes. Windows NT

will start, followed by the execution of Cluster Server.

18. Run Cluster Administrator and verify t hat the original groups and

resources are in their expected states. Then verify that the added groups
and resources are in their expected states.

There are two situations in which you would add or remove drives from the
shared storage:

■ When one of the drives fails. In this case, you are simply exchanging the

failed drive for a new one.

■ When you want to add capacity to your cluster.

In both sit uations, it is assumed you are employing RAID 1, 0+1, 4, or 5 for all
the devices in the storage unit.

Replacing a Failed Drive

The procedure for replacing a failed drive is completed within the storage area.
Neither Cluster Server nor Windows NT is aware of the change, and operation
of both cont inues without interruption.

IMPORTANT: If the failed drive was not configured to use RAID 1, 0+1, 4, or 5 (that is,
your drives have no fault tolerance), you may lose some or all of the data on the failed
drive.

See Chapter 3, “CR3500 Configuration Utility,” for instructions on replacing a
failed drive.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-13

Adding a Drive to Increase Storage Capacity

It is foreseeable that during the life of your ProLiant CL1850 you will need to
expand the capacity of your storage system. The f ol lowing steps describe how
to add a drive to the system and to allocate it to Cluster Server.

NOTE: You cannot increase the capacity of an existing logical drive in the shared storage
array.

1. Physically add the drives to the system.

2. Run the CR3500 Configuration Utility to configure the drives.

3. Run Windows NT Disk Administrator from server node 1 to assign a

drive letter to the newly created RAID volume.

4. While still runnin g Dis k Administrator, format the drives using NTFS.

5. Cluster Server requires a reboot of each server node following the

addition of a drive. Shut down both servers and reboot them.

6. Following the reboot, start Cluster Administrator and verify all newly

added drive volumes appear to the cluster as available disk resources.

Backing Up Your Cluster

The need for cluster backup is essential for both business- critical and non­business-critical data. As data becomes an increasingly valued company asset,
it needs to be backed up on a regular basis. The pr ocess of backing up data
will ensure that a company’s assets are secure and available when a disaster
strikes. The cluster itself provides a high degree of application availability but
does not prevent a user from deleti ng or corrupting a file or set of files.
Backing up a cluster’s data will increase the overall level of data availability.

Compaq currently suggests the use of one of the following solutions:

■ The first solution uses two tape backup subsystems, one tape backup

subsystem att ached to each server node.

■ The second solution shares a S C SI tape backup subsystem between the

two server nodes.

Each solution has its limitations from bot h the har dware and software
perspective. The limitations are due to the fact that tape backup software for
use with Win dows NT has not been updat ed for clustering. As Windows NT
clustering becomes more prevalent, tape backup vendors will update their
software to become cluster-aware.

The lack of cluster-aware tape backup software presents the user with two
problems:

■ First, there may be an inability to locate files when the cluster is in a

degraded state. For example, assume server node 1 owns a shared drive,
G:. A tape backup is performed fr om server no de 1 and drive G: is
backed up. At some point in the future, a need arises to restore some
files to drive G:. However, drive G: is in a failover state and is currently
owned by server node 2. An attempted restoration of the files from
server node 1 may fail if the tape bac kup software is unable t o
comprehend the shared characteristic of drive G:.

■ Second, if a failover or failback event occurs while a backup i s

executing, you may not be able to continue t he backup; you may be
required to restart the backup from the beginning. For example, if you
are backing up drive G: from server node 1 and a failover event moves
drive G: to server node 2, the backup process will abort since drive G: is
no longer accessible from server node 1. The backup process, if
configured as a cluster group and i f the backu p software su pports a
restart, can possibly be automatically restarted on server no de 2. Still,
the restarted backup will start at the beginning; the data placed on tape
by the inter rupted bac kup process o n server node 1 is lost.

System Management for Microsoft Windows NT Server 4.0, Enterprise Edition 5-15

Managing Cluster Performance

As applications or resources transfer from one server to a n other, the
performance of the clustered servers will likely change. The extent of the
performanc e change depends greatly on how well equipped the other se rver
node is to handle the increase in workload. This is especially obvious after a
server failure, where all of the cluster resources may move to the other server.

You can use the Windows NT Performance Monitor to observe and track
system performance. Some applications may also have their own internal
performance measurement capabilities. Constant monitoring of each system’s
performance in a cluster may identify a disparity in the workload being
performed by each server . Adjust the distribution of the clust er applica t ions so
that the overall cluster performance is maximized.

Dynamic load balancing is not available in the initial release of Microsoft’s
Cluster Server. However, Cluster Server does offer the ability to manually
load balanc e your server nodes. You can use information obt ained from
Performance Monitor to determine whether either of the server nodes is
operating at too high a performance level. Us e Cluster A dministrat or to fail
over as many cluster groups as necessary to balance the load of each server
node.

The timing of manuall y moving a cluster group to balanc e the load should
depend strongly on what type of group needs to be moved and how many
clients are using the group. File and print services are norma l ly not
business-critical, nor do they sustain an extrem ely high utilization rate. For
these reasons, file and print services are good candidates to move whenever
load balancing needs to occur, even when the overall cluster utilizati o n is high.

However, some applica t ions, such as databases, should not be moved from one
server to another duri ng peak processing periods. When a da tabase is m oved
from one server to another, the data base must be s hut down and r estarted.
During the time it takes the database to restart, users do not have access to the
database. In these cases, moving a database group to anot her server should be
performed during non peak hours.
