Using Serviceguard Extension for RAC, 8th Edition, March 2009

NOTE: Serviceguard Manager is the graphical user interface for Serviceguard. It is available

as a “plug-in” to the System Management Homepage (SMH). SMH is a web-based graphical

user interface (GUI) that replaces SAM as the system administration GUI as of HP-UX 11i v3

(but you can still run the SAM terminal interface; see “Using SAM” on page 32 of the Managing

Serviceguard Sixteenth Edition user’s guide).

Exporting with LVM Commands

Use the following commands to set up the same volume group on another cluster node. In this

example, the commands set up a new volume group on a system known as ftsys10. This

volume group holds the same physical volume that was created on a configuration node known

as ftsys9.

To set up the volume group on ftsys10 (and other nodes), use the following steps:

1. On ftsys9, copy the mapping of the volume group to a specified file.

# vgexport -s -p -m /tmp/vg_ops.map /dev/vg_ops

2. Still on ftsys9, copy the map file to ftsys10 (and to additional nodes as necessary.)

# rcp /tmp/vg_ops.map ftsys10:/tmp/vg_ops.map

3. On ftsys10 (and other nodes, as necessary), create the volume group directory and the

control file named group:

# mkdir /dev/vg_ops

# mknod /dev/vg_ops/group c 64 0xhh0000

For the group file, the major number is always 64, and the hexadecimal minor number has

the format:

0xhh0000

where hh must be unique to the volume group you are creating. If possible, use the same

number as on ftsys9. Use the following command to display a list of existing volume

groups:

# ls -l /dev/*/group

4. Import the volume group data using the map file from node ftsys9. On node ftsys10

(and other nodes, as necessary), enter:

# vgimport -s -m /tmp/vg_ops.map /dev/vg_ops

Installing Oracle Real Application Clusters

NOTE: Some versions of Oracle RAC requires installation of additional software. Refer to your

version of Oracle for specific requirements.

Before installing the Oracle Real Application Cluster software, make sure the cluster is running.

and to build the correct Oracle runtime executables. When the executables are installed to a

cluster file system, the Oracle installer has an option to install the executables once. When

executables are installed to a local file system on each node, the Oracle installer copies the

executables to the other nodes in the cluster.

For details on Oracle installation, refer to the Oracle installation documentation. As part of this

installation, the Oracle installer installs the executables and optionally, the Oracle installer can

build an Oracle demo database on the primary node. The demo database files can be either the

character (raw) device files names for the logical volumes created earlier, or the database can

reside on a cluster file system.
