5. Configure the Cluster Volume Manager (CVM)

Configure the system multi-node package, SG-CFS-pkg, to configure

and start the CVM/CFS stack. Unlike VxVM-CVM-pkg, the

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

and supports multiple subnets.

# cfscluster config -s

The following output will be displayed:

CVM is now configured

Starting CVM...

It might take a few minutes to complete

When CVM starts up, it selects a master node, which is the node

from which 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 - SLAVE

master: ever3b

mode: enabled: cluster active - MASTER

slave: ever3b

6. Converting Disks from LVM to CVM

You can 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 that uses the volume

group must be halted. This procedure is described in the Managing

Serviceguard Twelfth Edition user’s guide on HP-UX 11i v2

Appendix G.
