Using Serviceguard Extension for RAC, 9th Edition, September 2010

# 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 available on the primary node, and the Oracle DBA can use the raw
logical volume names.
Mirror Detachment Policies with CVM
The required CVM disk mirror detachment policy is “global”, — as soon as one node cannot see
a specific mirror copy (plex), all nodes cannot see it as well. The alternate policy is “local”— 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 reset 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 multipath storage using CVM are
described in the HP-UX documentation for the Veritas Volume Manager.
Oracle Demo Database Files
The following set of volumes is required for the Oracle demo database which you can create
during the installation process.
