IMPORTANT: The purpose of cmnotdisk.conf is to exclude specific devices, usually
CD and DVD drives, that Serviceguard does not recognize and which should not be
probed. Make sure you do not add a DEVICE_FILE entry in cmnotdisk.conf for
any device that should be probed; that is, disk devices being managed by LVM or LVM2.
Excluding any such device will cause cmquerycl to fail.
Setting Up and Running the Quorum Server
If you will be using a Quorum Server rather than a lock disk or LUN, the Quorum
Server software must be installed on a system other than the nodes on which your
cluster will be running, and must be running during cluster configuration.
For detailed discussion, recommendations, and instructions for installing, updating,
configuring, and running the Quorum Server, see HP Serviceguard Quorum Server Version
A.04.00 Release Notes at /www.hp.com/go/hpux-serviceguard-docs -> HP
Quorum Server Software.
Creating the Storage Infrastructure and Filesystems with LVM, VxVM and CVM
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”
(page 231).
Do this before you configure the cluster if you use a lock disk; otherwise it can be
done before or after.
• for Veritas Volume Manager, see“Creating a Storage Infrastructure with VxVM”
(page 239)
Do this before you configure the cluster if you use a lock disk; otherwise it can be
done before or after.
• for Veritas Cluster File System with CVM, see “Creating a Storage Infrastructure
with Veritas Cluster File System (CFS)” (page 261)
Do this after you configure the cluster.
• for Veritas Cluster Volume Manager, see “Creating the Storage Infrastructure with
Veritas Cluster Volume Manager (CVM)” (page 268)
Do this after you configure the cluster.
You can also use a mixture of volume types, depending on your needs.
