• Set the host_mode for each connection to Linux. In a redundant configuration, each node in the
cluster should have 2 connections, one for each port on the HBA.
• If Selective Storage Presentation (SSP) is used to control access to the LUNs, make sure to present
the LUNs used for storage by the database to ALL of the nodes in the cluster.
Installing HP PDC for Oracle10
Follow the procedure described in the Installing HP PDC for Oracle 10g RAC on Linux IA32 (PDC
Installation) document. The PDC installation procedure outlines all of the steps necessary to install and
configure the operating system, servers, and storage to run in an Oracle RAC environment. The PDC
kit provides a set of scripts that automate the installation of HP and Oracle software pieces. Once the
procedure has been completed, the system should be ready to accept an Oracle10g installation. Prior
to proceeding with the Oracle installation, the InfiniBand components should be configured.
Installation of InfiniBand software components
Follow the instructions in the Installing the HCA Drivers section of the Dual-Port 4x Adapter User
Guide to install the HCA drivers. The drivers will automatically be installed with support for all of the
protocols used by Oracle10g RAC including uDAPL and IPoIB.
Once the HCA drivers have been installed, follow the instructions in the Configuring IPoIB Drivers
section of the Dual-Port 4x Adapter User Guide to configure an IB interface for use as the cluster
interconnect. In most cases, the PDC installation scripts will have configured eth1 as the cluster
interconnect. The interface should be disabled and the ib interface should be configured as a
replacement. In order to disable eth1 and configure the virtual InfiniBand NIC, use the following
procedure on each node:
Unmount any OCFS volumes that are currently mounted.
1.
Shutdown the eth interface using the following command:
2.
ifdown ethX
Edit the /etc/sysconfig/network-scripts/ifcfg-ethX file, setting the ONBOOT parameter to the value
3.
NO in order to prevent the eth device from starting up automatically on boot. Below are the
contents of an example configuration file:
# Broadcom Corporation|NetXtreme BCM5703 Gigabit Ethernet
DEVICE=eth1
BOOTPROTO=static
HWADDR=00:02:A5:EF:5F:8E
IPADDR=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=no
TYPE=Ethernet
Create the /etc/sysconfig/network-scripts/ifcfg-ib0 file for the virtual InfiniBand NIC. Make sure
4.
to use the same networking configuration for the ib device as the eth device. Below are the
contents of an example configuration file:
DEVICE=ib0
BOOTPROTO=static
IPADDR=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
Startup the ib interface using the following command:
5.
ifup ib0
g
