Managing Serviceguard 12th Edition, March 2006

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4166
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 the display mode, such as 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, VxM-CVM-pkg to manage the cluster’s volumes.
You configure one heartbeat network for CVM 3.5 and VxM-CVM-pkg.
Multiple heartbeats are not supported. Using APA, Infiniband, or VLAN
interfaces as the heartbeat network is not supported.
CVM 4.1 without CFS VERITAS Cluster Volume Manager 4.1 uses
the system multi-node package SG-CFS-pkg to manage the cluster’s
volumes.
CVM 4.1 and the SG-CFS-pkg allow you to configure multiple heartbeat
networks. Using APA, Infiniband, or VLAN interfaces as the heartbeat
network is not supported.
CVM 4.1 with CFS CFS (VERITAS Cluster File System) is supported
for use with VERITAS Cluster Volume Manager Version 4.1.
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 ASCII file.
CVM 4.1 and the SG-CFS-pkg allow you to configure multiple heartbeat
networks. Using APA or Infiniband as the heartbeat network is not
supported.
You create a chain of dependencies for application failover package and
the non-failover packages:
1. The failover package’s applications should not run on a node unless
the mount point packages are already running.
