Managing Serviceguard Fifteenth Edition, reprinted May 2008

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4172
CAUTION Serviceguard manages Veritas processes, specifically gab and LLT,
through system multi-node packages. As a result, the Veritas
administration commands such as gabconfig, llthosts, and lltconfig
should only be used in display mode, for example gabconfig -a. You
could crash nodes or the entire cluster if you use Veritas commands such
as the gab* or llt* commands to configure these components or affect
their runtime behavior.
CVM Version 3.5
Veritas Cluster Volume Manager 3.5 uses the system multi-node package
VxVM-CVM-pkg to manage the cluster’s volumes.
You configure one heartbeat network for CVM 3.5 and VxVM-CVM-pkg.
Multiple heartbeats are not supported. Using APA, Infiniband, or VLAN
interfaces as the heartbeat network is not supported.
CVM 4.1 and later without CFS Veritas Cluster Volume Manager 4.1
and later uses the system multi-node package SG-CFS-pkg to manage
the cluster’s volumes.
CVM 4.1 and later and the SG-CFS-pkg require you to configure multiple
heartbeat networks, or a single heartbeat with a standby. Using APA,
Infiniband, or VLAN interfaces as the heartbeat network is not
supported.
CVM 4.1 and later with CFS CFS (Veritas Cluster File System) is
supported for use with Veritas Cluster Volume Manager Version 4.1 and
later.
The system multi-node package SG-CFS-pkg manages the cluster’s
volumes. Two sets of multi-node packages are also used: the CFS mount
packages, SG-CFS-MP-id#, and the CFS disk group packages,
SG-CFS-DG-id#. Create the multi-node packages with the cfs family of
commands; do not edit the configuration file.
CVM 4.1 and later and the SG-CFS-pkg require you to configure multiple
heartbeat networks, or a single heartbeat with a standby. Using APA,
Infiniband, or VLAN interfaces as the heartbeat network is not
supported.
