Using Serviceguard Extension for RAC, 4th Edition, February 2007

Serviceguard Configuration for Oracle 9i RAC
Creating a Storage Infrastructure with Veritas Cluster File System (CFS)
Chapter 3 139
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
or
mode: enabled: cluster active - MASTER
slave: ever3b
6. 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 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.
7. Initializing 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
LVM, you should use the pvremove command to delete the LVM
header data from all the disks in the volume group (this is not
necessary if you have not previously used the disk with LVM).
