Using Serviceguard Extension for RAC Version A.11.20 - (August 2011)

Using CVM 5.x or later

This section has information on how to set up the cluster and the system multi-node package with

CVM—without the CFS filesystem, on HP-UX releases that support them. See “About Veritas CFS

and CVM from Symantec” (page 15).

Preparing the Cluster and the System Multi-node Package for use with CVM 5.x or later

The following steps describe how to prepare the cluster and the system multi-node package with

CVM 5.x or later only.

1. Create the cluster file.

# cd /etc/cmcluster

# cmquerycl -C clm.asc -n ever3a -n ever3b

Edit the cluster file.

2. Create the cluster.

# cmapplyconf -C clm.asc

• Start the cluster.

# cmruncl

# cmviewcl

The following output will be displayed:

CLUSTER STATUS

ever3_cluster up

NODE STATUS STATE

ever3a up running

ever3b up running

3. Configure the Cluster Volume Manager (CVM).

To configure and start the CVM stack, you need to configure the system multi-node package,

SG-CFS-pkg. The SG-CFS-pkg does not restrict heartbeat subnets to a single subnet and

supports multiple subnets.

Use the cmapplyconf command:

# cmapplyconf -P /etc/cmcluster/cfs/SG-CFS-pkg.conf

# cmrunpkg SG-CFS-pkg

When CVM starts, it selects a master node. From this node, you must issue the disk group

configuration commands. To determine the master node, issue the following command from

each node in the cluster:

# vxdctl -c mode

The following output will be displayed:

mode: enabled: cluster active SLAVEmaster: ever3b

mode: enabled: cluster active MASTERmaster: ever3b

• Converting disks from LVM to CVM.

Use the vxvmconvert utility to convert LVM volume groups into CVM disk groups. Before

you can do this, the volume group must be deactivated, which means that any package
