HP Serviceguard Extension for RAC (SGeRAC) manual Installing Serviceguard Extension for RAC

Installing Serviceguard Extension for RAC

Installing Serviceguard Extension for RAC includes updating the software and rebuilding the kernel to support high availability cluster operation for Oracle Real Application Clusters.

Prior to installing Serviceguard Extension for RAC, the following must be installed:

•Correct version of HP-UX

•Correct version of Serviceguard

To install Serviceguard Extension for RAC, use the following steps for each node:

NOTE: All nodes in the cluster must be either SGeRAC nodes or Serviceguard nodes. For the up-to-date version compatibility for Serviceguard and HP-UX, see the SGeRAC release notes for your version.

1.Mount the distribution media in the tape drive, CD, or DVD reader.

2.Run Software Distributor, using the swinstall command.

3.Specify the correct input device.

4.Choose the following bundle from the displayed list:

5.After choosing the bundle, select OK to install the software.

Veritas Cluster Volume Manager (CVM) and Cluster File System (CFS)

CVM (and CFS – Cluster File System) are supported on some, but not all current releases of HP-UX. See the latest release notes for your version of Serviceguard at www.hp.com/go/hpux-serviceguard-docs.

NOTE: The HP-UX 11i v3 I/O subsystem provides multipathing and load balancing by default. This is often referred to as native multipathing. When CVM is installed on HP-UX 11i v3, DMP is the only supported multipathing solution, and is enabled by default.

About Multipathing

Multipathing is automatically configured in HP-UX 11i v3 (this is often called native multipathing), or in some cases can be configured with third-party software such as EMC Powerpath.

NOTE: The HP-UX 11i v3 I/O subsystem provides multipathing and load balancing by default. This is often referred to as native multipathing. When CVM is installed on HP-UX 11i v3, DMP is the only supported multipathing solution, and is enabled by default.

For more information about multipathing in HP-UX 11i v3, see the white paper HP-UX 11i v3 Native Multipathing for Mass Storage, and the Logical Volume Management volume of the HP-UX System Administrator’s Guide at www.hp.com/go/hpux-core-docs —> HP-UX 11i v3.

About Device Special Files

HP-UX releases up to and including 11i v2 use a naming convention for device files that encodes their hardware path. For example, a device file named /dev/dsk/c3t15d0 would indicate SCSI controller instance 3, SCSI target 15, and SCSI LUN 0. HP-UX 11i v3 introduces a new nomenclature for device files, known as agile addressing (also called persistent LUN binding). Under the agile addressing convention, the hardware path name is no longer encoded in a storage device’s name—each device file name reflects a unique instance number, for example /dev/ [r]disk/disk3, that does not need to change when the hardware path changes. Agile addressing is the default on new 11i v3 installations, but the I/O subsystem still recognizes the pre-11i v3
