Serviceguard Configuration for Oracle 10g RAC
Creating a Storage Infrastructure with CVM
Chapter 274
Preparing the Cluster and the System Multi-node Package for
use with CVM 4.x
1. Create the Cluster file:
# cd /etc/cmcluster
# cmquerycl -C clm.asc -n ever3a -n ever3b
Edit 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)
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.
Use the cmapplyconf command:
# 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:
