Building an HA Cluster Configuration
Creating the Storage Infrastructure and Filesystems with LVM and VxVM
Chapter 5208
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 208
• for VERITAS Volume Manager See “Creating a Storage
Infrastructure with VxVM” on page 215
• for VERITAS Cluster File System with CVM (on systems that
support it), See “Creating a Storage Infrastructure with VERITAS
Cluster File System (CFS)” on page 231
• for VERITAS Cluster Volume Manager (on systems that support it),
see “Creating the Storage Infrastructure and Filesystems with
VERITAS Cluster Volume Manager (CVM)” on page 243
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.
NOTE If you are configuring volume groups that use mass storage on HP's HA
disk arrays, you should use redundant I/O channels from each node,
connecting them to separate ports on the array. As of HP-UX 11i v3, the
I/O subsystem performs load balancing and multipathing automatically.
Creating a Storage Infrastructure with LVM
This section describes storage configuration with LVM. It includes
procedures for the following:
• Creating Volume Groups for Mirrored Individual Disks
• Distributing Volume Groups to Other Nodes
