Sample Configuration with HP Serviceguard Extension for RAG and Oracle Real Application Clusters 11g release 2 using Cluster File System

This value might be adjusted to a lower value for faster cluster reformation after careful consideration

of the guidelines in the Serviceguard user guide:

Create cluster (sample)

# cmapplyconf –C cluster.asc

Start the cluster:

# cmruncl

# cmviewcl

CLUSTER STATUS

cluster_ccia up

NODE STATUS STATE

ccia1 up running

ccia2 up running

Configure Cluster Volume Manager (CVM)

Configure the

SG-CFS-pkg system multi-node package so it configures and starts the CVM/CFS stack.

# cfscluster config -s

CVM is now configured

Starting CVM...

It might take a few minutes to complete

When CVM starts up, it selects a master node, and this is the node from which you must issue the disk

group configuration commands. To identify the master node, issue the following command from each

node in the cluster.

# vxdctl –c mode

mode: enabled: cluster active - SLAVE

master: ccia1

Initialize disks for CVM/CFS

You need to initialize the physical disks that will be employed in CVM disk groups. If a physical disk

has been previously used with Logical Volume Manager (LVM), you should use the

pvremove

command to delete the LVM header data from all of the disks in the volume group (this is not

necessary if you have not previously used the disk with LVM).

To initialize a disk for CVM, log on to the master node, then use the

vxdiskadm program to initialize

multiple disks, or use the

vxdisksetup command to initialize one disk at a time, as in the following

example:

# /etc/vx/bin/vxdisksetup -i disk23

In this sample configuration, only one disk is being used. This disk should be RAID protected, or some

other mechanism should be used to create a backup of this disk. If you are not using a RAID-protected

disk or creating a backup of this disk, use multiple disks to avoid a single point of failure.

Create disk groups for RAC

Use the

vxdg command to create disk groups. Use the –s option to specify shared mode, as in the

following example:

# vxdg –s init cfsdg1 disk23
