Managing Serviceguard Sixteenth Edition, March 2009

# /dev/vg01/lvoldb4 /general vxfs defaults 0 2 # logical volumes that
# /dev/vg01/lvoldb5 raw_free ignore ignore 0 0 # exist for Serviceguard's
# /dev/vg01/lvoldb6 raw_free ignore ignore 0 0 # HA package. Do not uncomment.
Create an entry for each logical volume, indicating its use for a file system or for a raw
device. Don’t forget to comment out the lines (using the # character as shown).
NOTE: Do not use /etc/fstab to mount file systems that are used by Serviceguard
packages.
Planning Veritas Cluster Volume Manager (CVM) and Cluster File System (CFS)
NOTE: Check the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in Compatibility
and Feature Matrix and the latest Release Notes for your version of Serviceguard for
up-to-date information on support for CVM and CFS: http://www.docs.hp.com
-> High Availability -> Serviceguard.
For a failover package that uses the CVM or CFS, you configure system multi-node
packages to handle the volume groups and file systems.
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.
