Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4168
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.
You create a chain of package dependencies for application failover
packages 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.
In the package’s configuration file, you fill out the dependency
parameter to specify the requirement SG-CFS-MP-id# =UP on the
SAME_NODE.
2. The mount point packages should not run unless the disk group
packages are running.
Create the mount point packages using the cfsmntadm and cfsmount
commands. Serviceguard names the mount point packages
SG-CFS-MP-id#, automatically incrementing their ID numbers. In
their configuration file, Serviceguard specifies the dependency on the
disk group packages.
3. The disk group packages should not run unless the CFS system
multi-node package (SG-CFS-pkg) is running to manage the volumes.
Create the disk group packages with the cfsdgadm. command.
Serviceguard names them SG-CFS-DG-id#, automatically
incrementing their ID number. In their configuration file,
Serviceguard specifies the dependency on the CFS system
multi-node package (SG-CFS-pkg).
