Serviceguard Configuration for Oracle RAC
Creating a Storage Infrastructure with LVM
Chapter 238
Creating a Storage Infrastructure with LVM
In addition to configuring the cluster, you create the appropriate logical
volume infrastructure to provide access to data from different nodes.
This is done with Logical Volume Manager (LVM), VERITAS Cluster
Volume Manager (CVM), or VERITAS Volume Manager (VxVM). LVM
and VxVM configuration are done before cluster configuration, and CVM
configuration is done after cluster configuration.
This section describes how to create LVM volume groups for use with
Oracle data. Before configuring the cluster, you create the appropriate
logical volume infrastructure to provide access to data from different
nodes. This is done with Logical Volume Manager. Separate procedures
are given for the following:
• Building Volume Groups for RAC on Mirrored Disks
• Building Mirrored Logical Volumes for RAC with LVM Commands
• Creating RAC Volume Groups on Disk Arrays
• Creating Logical Volumes for RAC on Disk Arrays
The Event Monitoring Service HA Disk Monitor provides the capability
to monitor the health of LVM disks. If you intend to use this monitor for
your mirrored disks, you should configure them in physical volume
groups. For more information, refer to the manual Using HA Monitors.
Building Volume Groups for RAC on Mirrored Disks
The procedure described in this section uses physical volume groups
for mirroring of individual disks to ensure that each logical volume is
mirrored to a disk on a different I/O bus. This kind of arrangement is
known as PVG-strict mirroring. It is assumed that your disk hardware
is already configured in such a way that a disk to be used as a mirror
copy is connected to each node on a different bus than the bus that is
used for the other (primary) copy.
For more information on using LVM, refer to the HP-UX Managing
Systems and Workgroups manual.
