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

To initialize a disk for CVM, log on to the master node, then use the vxdiskadm
program to initialize multiple disks, or use the vxdisksetup command to initialize
one disk at a time, as in the following example:
# /usr/lib/vxvm/bin/vxdisksetup -i /dev/dsk/c0t3d2
Creating Disk Groups for RAC
Use the vxdg command to create disk groups. Use the -s option to specify shared mode,
as in the following example:
# vxdg -s init ops_dg c0t3d2
Verify the configuration with the following command:
# vxdg list
NAME STATE ID
rootdg enabled 971995699.1025.node1
ops_dg enabled,shared 972078742.1084.node2
Creating Volumes
Use the vxassist command to create logical volumes. For example:
# vxassist -g log_files make ops_dg 1024m
This command creates a 1024 MB volume named log_files in a disk group named
ops_dg. The volume can be referenced with the block device file
/dev/vx/dsk/ops_dg/log_files or the raw (character) device file
/dev/vx/rdsk/ops_dg/log_files.
Verify the configuration with the following command:
# vxdg list
