Client LAN
Physically, the structure of the client network is no different than that used for
a non-clustered configuration.
To ensure continued access to the database when a cluster node is evicted from
the cluster, each network client should have physical network access to all of
the cluster nodes.
Software used by the client to communicate to the database must be able to
reconnect to another cluster node in the event of a node eviction. For example,
clients connected to cluster node1 need the ability to automatically reconnect
to another cluster if cluster node1 fails.

Installation and Configuration 5-3
Installing the Hardware
Setting Up the Nodes
Physically preparing the servers (nodes) for a cluster is not very different than
preparing them for individual use. You will install all necessary adapters and
insert all internal hard disks. You will attach network cables and plug in SCSI
and Fibre Channel cables. The primary difference will be setting up the shared
storage subsystem.
Set up the hardware on one node completely, then set up the rest of the nodes
identically to the first one. Do not load any software on any cluster node until
all the hardware has been installed in all cluster nodes. Before loading
software, read "Installing the Operating System Software" in this chapter to
understand the idiosyncrasies of configuring a cluster.
IMPORTANT: The servers in the cluster must be set up identically. The cluster
components common to all nodes in the cluster must be identical, for example, the
ProLiant server model, the cluster interconnect adapters, amount of memory, cache, and
number of CPUs must be the same for each cluster node.
While setting up the physical hardware follow the installation instructions in
your Compaq ProLiant Server Setup and Installation Guide and in your
Compaq ProLiant Server Installation Poster. When you are ready to install the
Compaq StorageWorks RAID Fibre Channel Host Bus Adapter (Fibre Host
Adapter) and your interconnect adapters, refer to the instructions in the pages
that follow.
NOTE: Compaq recommends that Automatic Server Recovery (ASR) be left at the default
values for clustered servers.
Installing the Fibre Host Adapter
The shared storage subsystem requires at least one Fibre Host Adapter in each
cluster node. Install this device as you would any other PCI adapter. If you
need specific instructions refer to the Compaq StorageWorks Fibre Channel
Host Adapter Installation Guide.

5-4 Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i Release 8.1.5 Administrator Guide
Installing the Cluster Interconnect Adapters
You can implement the cluster interconnect in a PDC/ 1000 cluster using
Ethernet adapters or ServerNet PCI Adapters.
Ethernet Cluster Interconnect
Install an Ethernet adapter into the cluster node for a dedicated Ethernet cluster
interconnect. For recommended dual-port and single-port Ethernet adapters for
your cluster, see the Compaq Parallel Database Cluster Model PDC/O1000
for Oracle8i Parallel Server Release 8.1.5 Certification Matrix at:
www.compaq.com/highavailability/
If you need specific instructions on how to install an adapter, refer to the
documentation of the Ethernet adapter you are installing or refer to the user
guide of the ProLiant server you are using.
ServerNet Cluster Interconnect
Install one ServerNet PCI Adapter into each cluster node. ServerNet PCI
Adapters are dual-ported, each having an X port and a Y port thus providing
two independent data paths. For specific instructions on how to install a
ServerNet PCI Adapter, see the ServerNet PCI Adapter Installation Guide.
IMPORTANT: The ServerNet PCI Adapter Installation Guide instructs you to install
ServerNet drivers provided on the CD in the kit with the ServerNet PCI Adapter. DO NOT
install these drivers. You will be instructed later to install ServerNet drivers using the
PDC/ 1000 CD.
Installing the Client LAN Adapters
Unlike other clustering solutions, the PDC/ 1000 does not allow transmission
of intra-cluster communication across the client LAN. All such
communication must be sent over the cluster interconnect.
Install a NIC into each cluster node for a client LAN. Configuration of the
client LAN is defined by site requirements. If you need specific instructions on
how to install an adapter, refer to the documentation of the adapter you are
installing or refer to the user guide of the ProLiant server you are using.

Installation and Configuration 5-5
Setting Up and Configuring the RA4000 External
Storage Subsystem
Follow the instructions in the Compaq StorageWorks RAID Array 4000 User
Guide to set up the Compaq StorageWorks RAID Array 4000 (RA4000
Array), the Compaq StorageWorks Fibre Channel Storage Hub (Storage Hub),
the Compaq StorageWorks RAID Array 4000 Array Controller (RA4000
Array Controller), and the Fibre Channel cables.
IMPORTANT: When installing an RA4000 Array, do not mount the Fibre Channel cables
on cable management arms. Support the Fibre Channel cable so that a bend radius at the
cable connector is not less than 3 inches.
Note that the Compaq StorageWorks RAID Array 4000 User Guide shows you
how to install these devices for a single server. Because clustering requires
shared storage, you will need to install these devices for multiple servers. This
will require running extra Fibre Channel cables from the Storage Hub to the
other servers. Both 7-port and 12-port hubs are supported.
IMPORTANT: Although you can configure the RA4000 Array with a single drive installed,
it is strongly recommended for cluster configuration that all shared drives be in the
RA4000 Array before running the Compaq Array Configuration Utility.
Figure 5-1 shows an RA4000 Array connected to four clustered servers
through a Storage Hub.

Compaq Array Configuration Utility
The Array Configuration Utility is used to set up the hardware aspects of any
drives attached to an array controller, including the drives in the shared
RA4000 Arrays. The Array Configuration Utility stores the drive
configuration information on the drives themselves; therefore, after you have
configured the drives from one of the cluster nodes, it is not necessary to
configure the drives from the other cluster node.
Before you run the Array Configuration to set up your drive arrays during the
SmartStart installation, refer to the instructions in the "Installing the Operating
System Software" section of this chapter. These instructions include clustering
information that is not included in the Compaq StorageWorks RAID Array
4000 User Guide.
For detailed information about configuring the drives using the Array
Configuration Utility, see the Compaq StorageWorks RAID Array 4000 User
G u i d e.
For information about configuring your shared storage subsystem with RAID,
see Chapter 4, "Planning."
Cabling the Cluster Interconnect
If the cluster uses an Ethernet cluster interconnect, one Ethernet switch is
required for clusters of three or more nodes. If there are only two nodes in a
cluster, you can use an Ethernet switch or hub and standard Ethernet cables to
connect the nodes. It is also possible to directly connect two nodes with an
Ethernet crossover cable.
If ServerNet is the cluster interconnect, one ServerNet Switch is required for
clusters of three or more nodes. When two nodes are connected by ServerNet,
they can be connected directly using ServerNet cables. They can also be
connected through a ServerNet Switch.
NOTE: If the current cluster contains two nodes but you anticipate adding nodes in the
future, consider installing a ServerNet Switch now.
For illustrations of cabling the cluster components, see the Compaq Parallel
Database Cluster Model PDC/ 1000 for Oracle8i Release 8.1.5 Configuration
Poster.

Installation and Configuration 5-7
Ethernet Cluster Interconnect for Two Nodes
If there are only two nodes in a cluster, you can cable the Ethernet cluster
interconnect using a crossover cable.
To install an Ethernet crossover cable:
1. Insert one end of an Ethernet crossover cable into a port on an Ethernet
adapter for the cluster interconnect.
2. Insert the other end of the crossover cable into a port on an Ethernet
adapter for the cluster interconnect on the second node.
Another cabling alternative for a two-node cluster is using standard Ethernet
cables and an Ethernet hub or switch.
To install an Ethernet hub or switch in a two-node cluster:
1. Insert one end of an Ethernet cable for the cluster interconnect into a
port on an Ethernet adapter in a cluster node. If you are using the
recommended dual-port Ethernet adapter, select either port. If you are
using the recommended single-port Ethernet adapter, connect the cluster
interconnect cable to the port on that adapter.
2. Connect the other end of the cluster interconnect Ethernet cable to a port
in the Ethernet hub or switch.
3. Repeat steps 1 and 2 for the second cluster node.
Ethernet Cluster Interconnect for Three or
More Nodes
To maintain good network performance across the cluster interconnect in a
cluster containing three or more nodes, Compaq requires using a 100 Mbit/sec
Ethernet switch. An Ethernet hub is not supported for more than two nodes.
Using an Ethernet switch requires that you use standard Ethernet cables.
Ethernet crossover cables will not work with a switch.
To install an Ethernet switch in a cluster with three or more nodes:
1. Insert one end of an Ethernet cable for the cluster interconnect into a
port on an Ethernet adapter in a cluster node. If you are using the
recommended dual-port Ethernet adapter, select either port. If you are
using the recommended single-port Ethernet adapter, connect the cluster
interconnect cable to the port on that adapter.
2. Connect the other end of the cluster interconnect Ethernet cable to a port
in the Ethernet switch.

ServerNet Cluster Interconnect
If there are only two nodes in the cluster, ServerNet PCI Adapters can be
connected directly using a ServerNet cable between the nodes or through a
ServerNet Switch. If the cluster contains three or more nodes, ServerNet PCI
Adapters must be connected through a ServerNet Switch.
To directly connect two nodes using a ServerNet cable:
1. Insert one end of the ServerNet cable into the X port of the ServerNet
PCI Adapter in the first node.
2. Insert the other end of the ServerNet cable into to the X port of the
ServerNet PCI Adapter in the second node.
If you do not want to use the X ports, connect the two nodes in a similar
fashion using the Y port on each ServerNet PCI Adapter.
To connect two or more nodes using a ServerNet Switch:
1. Insert one end of a ServerNet cable into the X port of the ServerNet PCI
Adapter in a cluster node.
2. Connect the other end of the ServerNet cable to a port on the ServerNet
Switch.
If you do not want to use the X ports, connect the two nodes in a similar
fashion using the Y port on each ServerNet PCI Adapter.

Cabling the Client LAN
You can use any TCP/IP network to connect to a client LAN. The following
procedure contains instructions for cabling an Ethernet client LAN.
To cable an Ethernet client LAN:
1. Insert one end of an Ethernet cable into a port on an Ethernet adapter
designated for the client LAN in a cluster node.
If you are using the recommended dual-port Ethernet adapter for the
cluster interconnect, connect the client LAN to the empty port.
If you are using the recommended single-port adapter for the cluster
interconnect, connect the client LAN to the port on the embedded
adapter or to another single-port Ethernet adapter.
2. Connect the node to the client LAN by inserting the other end of the
client LAN Ethernet cable to a port in the Ethernet hub
or switch.
3. Repeat steps 1 and 2 for all other cluster nodes.
Redundant Client LAN
If you elect to install an Ethernet client LAN, it requires two single-port
Ethernet adapters or one dual-port Ethernet adapter in each cluster node. It
also requires two Ethernet hubs or switches, and one Ethernet crossover cable
is required between the Ethernet hubs or switches. Using redundant crossover
cables between the nodes is not supported.

Power Distribution and Power Sequencing
Connect most cluster components to a Compaq power distribution unit (PDU).
PDUs connect to an uninterruptible power source (UPS) or building power.
The power distribution units and UPSs are the only cluster components
connected to a building power source. If there is no UPS, the PDU plugs into
building power.
Server Power Distribution
The following figure shows an example of server power distribution for a
three-node cluster. Power supply #1 of each server is connected to PDU #1.
Power supply #2 of each server is connected to PDU #2.
PDU #1 is connected to UPS #1, and PDU #2 is connected to UPS #2. Each
UPS is connected to building power.

Installation and Configuration 5-13
RA4000 Array Power Distribution
An RA4000 Array can have up to two power supplies. If each array has two
power supplies, the power distribution (with respect to connecting them to
PDUs and UPSs) can be configured similarly to the example shown for server
power distribution. Substituting RA4000 Arrays for ProLiant servers in Figure
5-5, you can provide two redundant paths from the RA4000 Arrays to building
power.
If each RA4000 Array has one power supply, connect the array to a PDU,
connect the PDU to a UPS, and then connect the UPS to building power. If
there is no UPS, connect the PDU directly to building power.
Power Sequencing
Be sure to power up the cluster components in the following order:
1. Storage Hubs
(Power is applied when the AC power cord is plugged in.)
2. RA4000 Arrays
3. Ethernet or ServerNet switches
4. ProLiant servers
Power off the cluster components in the reverse order of the power-on
sequence: servers, switches, RA4000 Arrays, and Storage Hubs. Shutting
down and powering off the servers first allows them to perform tasks such as
flushing queued database write transactions to disk and properly terminating
running processes.

Installing the Operating System Software
Installing clustering software requires several specific steps and guidelines that
might not be necessary when installing software on a single server. Read and
understand the following items before proceeding with any specific software
installation steps.
3 Because a PDC/ 1000 configuration can contain multiple servers, have
sufficient software licensing rights to install Windows NT Server
software applications on each server.
3 Clustering hardware must be installed before you install the software.
3 Power on the cluster as instructed previously in "Power Sequencing."
3 SmartStart runs the Compaq Array Configuration Utility, which is used
to configure the drives in the RA4000 Array. The Array Configuration
Utility stores the drive configuration information on the drives
themselves. After you have configured the shared drives from one of the
cluster nodes, it is not necessary to configure the drives from the other
cluster node.
When the Array Configuration Utility runs on the first cluster node,
configure the shared drives in the RA4000 Array. When SmartStart runs
the utility on the other cluster nodes, you will be presented the
information on the shared drives that was entered when the Array
Configuration Utility was run on the first node. Accept the information
as presented and continue.
NOTE: Local drives on each cluster node still need to be configured.
3 When you set up an Ethernet cluster interconnect, be sure to select
TCP/IP as the network protocol. The Ethernet cluster interconnect
should be on its own subnet.
IMPORTANT: The IP addresses of the Ethernet cluster interconnect must be static, not
dynamically assigned by DHCP.
3 Set up unique IP addresses and node names for each node in the hosts
and lmhosts files located at %SystemRoot%\system32\drivers\etc.
Y For an Ethernet cluster interconnect, one IP address and node name
is for the cluster interconnect, and the other IP address and node
name is for the client LAN. Both entries are required for each node
in the cluster.

Installation and Configuration 5-15
Y For a ServerNet cluster interconnect, an IP address and node name is
required only for the client LAN. This entry is required for each
node in the cluster.
Y After setting up these file entries, restart the node so it picks up the
correct IP addresses.
3 Run Windows NT Server Disk Administrator on each node to verify you
can see the shared storage subsystem resources on all RA4000 Arrays
and select the Commit Changes option in Disk Administrator. Restart all
nodes.
Using SmartStart
CAUTION: Automated installation using SmartStart assumes that it is being
installed on new servers. If there is any existing data on the servers, the data
will be destroyed.
You will need the following during SmartStart installation:
3 SmartStart and Support Software 4.20 or later
3 Windows NT Server Standard or Enterprise Edition 4.0 and Service
Pack 3 or 4
IMPORTANT: Compaq recommends Service Pack 4 of Windows NT Server for a
redundant Ethernet cluster interconnect or client LAN. Using Service Pack 3 requires
installing the approved Microsoft patch (hot fix).
3 SmartStart installation poster
Cluster-Specific SmartStart Installation
The SmartStart installation poster describes the general flow of configuring
and installing software on a single server. The installation for a PDC/ 1000
will be similar.
The one difference is that through the Array Configuration Utility, SmartStart
gives you the opportunity to configure the shared drives on all servers. For
cluster configuration, you should configure the drives on the first server, then
accept the same settings for the shared drives when given the option on the
other servers.

Automated Installation Steps
1. Place the SmartStart and Support Software CD in the CD-ROM drive of
a cluster node.
2. Select the Assisted Integration installation path.
3. When prompted, insert the Server Profile Diskette into the floppy disk
drive.
4. Select Windows NT Server Standard Edition or Windows NT Server
Enterprise Edition as the operating system.
5. Continue with the Assisted Integration installation. Windows NT Server
is installed as part of this process.
NOTE: When configuring the network as part of Windows NT Server, you will be
prompted for the IP Addresses to be associated with the network ports. Assign the initial
port with the IP address to be associated with the client LAN and assign the other port
with the IP Address to be associated with the cluster interconnect.
NOTE: When using the Array Configuration Utility, it is only necessary to configure the
shared drives during node1 setup. When configuring the other nodes, the utility shows the
results of the shared drives configured during node1 setup.
6. During the Windows NT Server installation process, you are asked if
you want to install additional services. If you intend to install ServerNet
SNMP agents later, click Add and select SNMP Service.
7. When prompted, install Windows NT Server Service Pack 3 or 4. If you
are installing Windows NT Server/Enterprise Edition after the Service
Pack, the Enterprise Edition Installer loads automatically. Do not install
Microsoft Cluster Server.
8. When prompted, load the Compaq Software Support Diskette (SSD). Do
not restart.
9. Go to the control panel, double-click the Network icon, select the
Protocols tab, and double-click TCP/IP. The TCP/IP Properties dialog
box appears. The IP Addresses that were entered during the installation
are shown. Note which IP addresses are associated with which ports.
10. Enter unique IP addresses and node names for each node in the hosts
and lmhosts files located at %SystemRoot%\system32\drivers\etc.
For an Ethernet cluster interconnect, one IP address and node name is
for the cluster interconnect, and the other IP address and node name is
for the client LAN. For example, node1 for the client LAN and
node1_san for the cluster interconnect. (The "_san" stands for system
area network.)

Installation and Configuration 5-17
For a ServerNet cluster interconnect, an IP address and node name is
required only for the client LAN. This entry is required for each node in
the cluster.
11. Restart the node so it picks up the IP addresses. Due to the complexity
with Windows NT Server and multiple-NIC servers, you need to verify
that the correct IP addresses are assigned to the right ports/NICs and that
the Ethernet cables are connected to the right ports. If IP addresses are
not assigned to the correct port, Oracle software and external programs
cannot communicate over the proper network link. The next step
describes how perform this verification.
12. Verify that the IP addresses for the client LAN and cluster interconnect
are correctly assigned by pinging the machine host name. (Find this
name by selecting the Identification tab in the Network control panel.)
The IP address returned by the ping utility is one of the IP addresses you
specified; it is the IP address that Windows NT Server assigned to the
client LAN.
13. If the ping command does not return the IP address you specified in the
TCP/IP Properties dialog box for the client LAN port and you are using
Service Pack 3:
a. Swap the IP addresses specified for the client LAN port and cluster
interconnect port.
b. Click OK and restart the system if prompted.
c. Now that you know which Ethernet port Windows NT Server
assigned to the client LAN and cluster interconnect, verify that the
Ethernet cables are connected to the appropriate ports. You do not
need to modify the hosts or lmhosts files.
14. If the ping command does not return the IP address you specified in the
TCP/IP Properties dialog box for the client LAN port and you are using
Service Pack 4:
a. Double-click the Network icon in the Control Panel and select the
Bindings tab.
b. Select all protocols in the Show Bindings for scroll box.
c. Click + (plus sign) next to the TCP/IP protocol. A list of all installed
Ethernet NICs appears, including the slot number and port number
of each. Windows NT Server uses the NIC at the top of the list for
the client LAN.
d. Change the binding order of the NICs to put the NIC you specified
for the client LAN at the top of the list. Find the client LAN NIC in
the list and select it.

e. With the client LAN NIC selected, click the Move Up button to
position this NIC to the top of the list.
f. Click Close on the dialog box and restart the node when prompted.
IMPORTANT: Record the cluster interconnect node name, the client LAN node name, and
the IP addresses assigned to them. You will need this information later when installing
Compaq OSDs.
15. If you are installing node1, open Windows NT Server Disk
Administrator to create extended disk partitions and logical partitions
within the extended partitions. Create all disk partitions on a shared
storage subsystem from node1, select Commit Changes Now from the
File menu, and restart the node. (If you are installing a node other than
node1, skip to the next step.)
16. If you are installing a node other than node1, open Disk Administrator
to verify that the same shared disk resources are seen from this node as
they are from other installed nodes in the cluster.
17. For partitions created on a shared storage subsystem, remove any drive
letters that Windows NT Server has assigned to the partitions. Using
Windows NT Server Disk Administrator, remove the drive letters. If
you create more partitions than you have available drive letters, restart
the node and remove any new drive letters that have been assigned. For
more information on creating partitions and unassigning drive letters,
refer to the Oracle8i Parallel Server Setup and Configuration Guide
Release 8.1.5.
18. Repeat steps 1 through 17 on all other cluster nodes.
19. After configuring all nodes in the cluster, verify the network
connections by pinging all nodes in the cluster from each cluster node.
For either cluster interconnect, use the client LAN node name, for
example, node1 with the ping command. If you are using an Ethernet
cluster interconnect, also use the Ethernet cluster interconnect node
name, for example, node1_san, with the ping command.
Compaq OSD Installation
Use the Oracle Universal Installer (OUI) program to install the Compaq
operating system dependent modules (OSDs) for Oracle8i Parallel Server.
Compaq supplies two software packages with the OUI. One installs Compaq
OSDs for an Ethernet cluster interconnect. Another installs Compaq OSDs,
ServerNet device drivers, and (optionally) ServerNet SNMP agents for a
ServerNet cluster interconnect.

Installation and Configuration 5-19
NOTE: If you elect to install SNMP agents, the Microsoft SNMP Service must be installed
and running before installing the agents with the OUI.
The OUI runs from one node in the cluster and performs the following tasks:
3 Copies the OSDs to the internal hard drive of all cluster nodes.
3 Sets up registry entries for file location and standard registry parameters
for the OSDs on all cluster nodes.
3 If the cluster interconnect is ServerNet, the OUI installs and configures
ServerNet device drivers and (optionally) ServerNet SNMP agents on
all cluster nodes.
From one node in the cluster, the OUI installs and configures OSDs, ServerNet
device drivers, and (optionally) ServerNet SNMP agents on the other nodes in
the cluster, provided that:
3 The servers are communicating through a local area network using a
TCP/IP protocol.
3 The person running the OUI program has administrator privileges on
every node.
Verifying Installation of the SNMP Service
If you decide to install the SNMP agent for the ServerNet PCI Adapter or the
ServerNet Switch, or both, the Microsoft SNMP Service must be installed and
running before installing any SNMP agents with the OUI.
Verify this service is installed by going to the Services applet of the Control
Panel. If there is an entry for SNMP Service, it is installed.
If SNMP Service is not listed, do the following to install it:
1. Insert the Windows NT Server Standard or Enterprise Edition 4.0 CD
into the CD-ROM drive.
2. Go to the Network applet of the Control Panel and select the Services
tab.
3. Click Add on the Network Services dialog box. The Select Network
Service dialog box appears.
4. Select SNMP Service from the Network Service list and click OK. The
Setup Copy dialog box appears.

5. Verify that the drive letter displayed in the dialog box refers to the
CD-ROM drive and click Continue. The Microsoft SNMP Properties
dialog box appears.
6. Type the Optional Contact and Locations information and review the
Service information. The default setting for the Service information is
usually fine.
7. Select the Traps tab on the Microsoft Properties dialog box.
8. Type a Community Name, for example, public, and click OK. The
Community Name is required to allow Compaq Insight Manager to
communicate with the system.
9. Choose the Network applet to complete the installation. The applet
prompts you to restart the server.
10. Click Yes and wait for the server to restart.
11. Reinstall the Service Pack and restart the node when prompted. Make
sure you don't overwrite any drivers installed since the last time the
Service Pack was applied.
12. Repeat steps 1 through 11 for all cluster nodes.
Verifying Cluster Communications
IMPORTANT: The successful completion of the OUI program depends on TCP/IP
connectivity being set up correctly. It also depends on the person running the OUI having
administrator access to every node in the cluster. Before running the OUI, verify cluster
communications and the administrator privileges of the person performing the installation.
If the OSDs do not install successfully, the OUI will not offer the option to install Oracle8i
Parallel Server.
The Compaq operating system dependent modules (OSDs) are installed from
one node in the cluster (the installing node). The node on which you run the
OUI program must be able to communicate with every other node in the
cluster in order to copy information to all other cluster nodes.
Use the ping utility to verify that each node in the cluster can communicate
with every other node.
Run the ping utility from each node in the cluster. Ping the client LAN name
of every node in the cluster. The client LAN name and client LAN IP address
were assigned to each cluster node while using SmartStart to perform the
automated software installation steps.

Installation and Configuration 5-21
If you are using an Ethernet cluster interconnect, a cluster interconnect name
and IP address were assigned to each cluster node. Ping the Ethernet cluster
interconnect name of every node in the cluster.
When using the client LAN name with the ping command, the IP address
displayed by the ping utility should be the client LAN IP address. When using
an Ethernet cluster interconnect name, the IP address displayed by the ping
utility should be an Ethernet cluster interconnect address. If the ping utility
does not return the expected IP addresses, check the entries in the hosts and
lmhosts files at %SystemRoot%\system32\drivers\etc.
For example, the command ping node1 should return the following type of
information.
Pinging node1.loc1.yoursite.com [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128

Mounting Remote Drives and Verifying
Administrator Privileges
Because the OUI installs and configures OSDs, ServerNet device drivers, and
(optionally) ServerNet SNMP agents on the other nodes in the cluster from the
installing machine, you must first mount a drive on all remote nodes. Remote
nodes are those nodes other than the node on which the OUI is running (the
installing machine).
The drive you mount should be the drive the OUI will write to, and it must be
the same drive on all cluster nodes. There should be at least five megabytes of
space on the remote drives.
The net use command can be used to mount drives on remote nodes. The
person running the net use command must have administrator privileges.
Therefore, running the net use command not only mounts drives on remote
nodes but also verifies the administrator privileges of the installer.
Administrator privileges are required for most installation tasks, such as
installing device drivers and changing registry entries. To install the OSDs,
you must have administrator privileges on each node from the installing
machine.

5-22 Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i Release 8.1.5 Administrator Guide
To mount drives on remote nodes, enter a net use command from a C: prompt
on the installing machine. Enter one instance of the command for each remote
cluster node. The following example mounts the C: drive on a remote node.
C: net use \\machine_name\C$ * /User:
The "*" results in the system prompting you for a password, and the password
is not echoed. (The Map Network Drive option in Windows NT Explorer is an
alternative to the net use command.)
If successful, the net use command returns:
"The command completed successfully."
If the command is not successful, make sure the administrative shares on
remote node drives are present.
Installing Ethernet OSDs
To install the OSDs for an Ethernet cluster interconnect:
1. Log in as a user who has administrator privileges on all nodes in the
cluster. If all servers in the cluster are in the same Windows NT Server
domain, log in as a user who is a member of the Domain Administrators
group. If the servers are in different domains, create a local user on each
server with the same Windows NT Server user name and password on
each node. Then make that local user a member of the local
Administrators group on each node before installing the OSDs.
2. Insert the Compaq Parallel Database Cluster Model PDC/ 1000 for
Oracle8i Parallel Server Release 8.1.5 Ethernet Clustering Software CD
into the CD-ROM drive.
3. If autorun is enabled, the Oracle Universal Installer welcome screen
appears.
If autorun is disabled, enter d:\setup at a C: prompt. Substitute the letter
assigned to the CD drive for d. The Oracle Universal Installer welcome
screen appears.
