Using Serviceguard Extension for RAC, 4th Edition, February 2007

Serviceguard Configuration for Oracle 10g RAC
Creating a Storage Infrastructure with CVM
Chapter 286
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.
