Serviceguard Configuration for Oracle RAC
Creating a Storage Infrastructure with CVM
Chapter 256
# 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. The following is
an 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
IMPORTANT After creating these files, use the vxedit command to change the
ownership of the raw volume files to oracle and the group membership
to dba, and to change the permissions to 660. Example:
# cd /dev/vx/rdsk/ops_dg
# vxedit -g ops_dg set user=oracle *
# vxedit -g ops_dg set group=dba *
# vxedit -g ops_dg set mode=660 *
The logical volumes are now available on the primary node, and the raw
logical volume names can now be used by the Oracle DBA.
