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

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 well. The
alternate policy is ‘local’, which means that if one node cannot see a specific mirror
copy, then CVM will deactivate access to the volume for that node only.
This policy can be re-set on a disk group basis by using the vxedit command, as
follows:
# vxedit set diskdetpolicy=global <DiskGroupName>
NOTE: The specific commands for creating mirrored and multi-path storage using
CVM are described in the HP-UX documentation for the Veritas Volume Manager.

The following set of volumes is required for the Oracle demo database which you can
create during the installation process.
