Using Serviceguard Extension for RAC, 5th Edition, June 2007

Serviceguard Configuration for Oracle 9i RAC
Creating a Storage Infrastructure with CVM
Chapter 3 171
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 c4t4d0
4. Creating Volumes and Adding a Cluster Filesystem
# vxassist -g ops_dg make vol1 10240m
# vxassist -g ops_dg make vol2 10240m
# vxassist -g ops_dg make volsrvm 300m

SG-CFS-pkg up running enabled yes
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.
Mirror Detachment Policies with CVM The required CVM disk
mirror detachment policy is ‘global’, which means that as soon as one
node cannot see a specific mirror copy (plex), all nodes cannot see it as
