Building an HA Cluster Configuration
Creating the Storage Infrastructure and Filesystems with LVM and VxVM

Creating the Storage Infrastructure and
Filesystems with LVM and VxVM
In addition to configuring the cluster, you create the appropriate logical
volume infrastructure to provide access to data from different nodes.
This is done several ways:
• for Logical Volume Manager, see “Creating a Storage Infrastructure
with LVM” on page 209
• for VERITAS Volume Manager See “Creating a Storage
Infrastructure with VxVM” on page 218
• for VERITAS Cluster File System with CVM, See “Creating a
Storage Infrastructure with VERITAS Cluster File System (CFS)” on
page 240
• for VERITAS Cluster Volume Manager, see “Creating the Storage
Infrastructure and Filesystems with VERITAS Cluster Volume
Manager (CVM)” on page 251
You can also use a mixture of volume types, depending on your needs.
LVM and VxVM configuration is done before configuring the cluster.
CVM and CFS configuration is done after configuring the cluster.
Creating a Storage Infrastructure with LVM
This section describes storage configuration with LVM. Separate
procedures are given for the following:
• Creating Volume Groups for Mirrored Individual Disks
• Creating Volume Groups for Disk Arrays Using PV Links
• Distributing Volume Groups to Other Nodes
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 High
Availability Monitors.
