Serviceguard Configuration for Oracle 9i RAC
Creating a Storage Infrastructure with CVM

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.
Using CVM 3.x
This section has information on how to prepare the cluster with CVM 3.x
(on HP-UX releases that support Veritas CFS and CVM; see “About
Veritas CFS and CVM from Symantec” on page 22).
Preparing the Cluster for Use with CVM 3.x
In order to use the Veritas Cluster Volume Manager (CVM) version 3.5,
the cluster must be running with a special CVM package. This means
that the cluster must already be configured and running before you
create disk groups.
NOTE Cluster configuration is described in the previous section.
To prepare the cluster for CVM disk group configuration, you need to
ensure that only one heartbeat subnet is configured. Then use the
following command, which creates the special package that
communicates cluster information to CVM:
# cmapplyconf -P /etc/cmcluster/cvm/VxVM-CVM-pkg.conf
