Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5 265
You can confirm this using the cmviewcl command. This output shows
results of the CVM 3.5 command above.
CLUSTER STATUS
example up
NODE STATUS STATE
ftsys9 up running
ftsys10 up running
MULTI_NODE_PACKAGES:
PACKAGE STATUS STATE AUTO_RUN SYSTEM
VxVM-CVM-pkg up running enabled yes
NOTE Do not edit system multi-node package configuration files, such as
VxVM-CVM-pkg.conf and SG-CFS-pkg.conf. Create and modify
configuration using the cfs admin commands listed in Appendix A.
Starting the Cluster and Identifying the Master Node
If it is not already running, start the cluster. This will automatically
activate the special CVM package:
cmruncl
When CVM starts up, it selects a master node, and this 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
One node will identify itself as the master. Create disk groups from this
node.
Initializing Disks for CVM
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).
