Using Serviceguard Extension for RAC, 6th Edition, April 2008

NOTE: To prepare the cluster for CVM configuration, you need to be sure
MAX_CONFIGURED_PACKAGES to minimum of 3 (the default value for
MAX_CONFIGURED_PACKAGES for Serviceguard A.11.17 is 150) cluster
configuration file. In the sample set the value to 10.
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)
Configure the system multi-node package, SG-CFS-pkg, to configure and start
the CVM stack. Unlike VxVM-CVM-pkg, the SG-CFS-pkg does not restrict heartbeat
subnets to a single subnet and supports multiple subnets.
# cmapplyconf -P /etc/cmcluster/cfs/SG-CFS-pkg.conf
# cmrunpkg SG-CFS-pkg
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 - SLAVEmaster: 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 that uses the volume group must be halted. This
