READ ME before using the Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide (April 2011)

Maximum number of nodes
A maximum of 16 nodes are supported in a Serviceguard Storage Management Suite CFS
configuration.
Single network option
The Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide refers to the
option for a single network during installation. This is not relevant in a Serviceguard Storage
Management installation. SG SMS creates GAB/LLT configurations on the same networks that have
Serviceguard heart beats.
Configuring low priority a link
The Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide discusses
configuring a low priority link. This is not relevant and should not be done in a Serviceguard
Storage Management Suite environment.
Split-brain and jeopardy handling
The Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide requires I/O
Fencing and SCSI-3 PGR for split-brain and jeopardy handling. This is not relevant in a Serviceguard
Storage Management Suite environment, where Serviceguard provides mechanisms for handling
split-brain, data integrity, maintaining cluster coherency, and membership with multiple redundant
Servicegaurd heart beat networks.
Coordination point server
The Coordination Point Server is mentioned in several places in the Veritas Storage Foundation™
5.1 SP1 Cluster File System Administrator's Guide, but it is not used in a Serviceguard Storage
Management Suite environment, where Serviceguard performs these functions.
Administering SFCFS global clusters
The Administering SFCFS global clusters section in the Veritas Storage Foundation™ 5.1 SP1
Cluster File System Administrator's Guide discusses setting up a disaster recovery “fire drill”. This
fire drill procedure is not supported in a Serviceguard Storage Management Suite environment.

Clustered network file system (NFS)
Chapter 5 in the Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide
discusses using Clustered NFS, but it is not specific to a Serviceguard Storage Management Suite
environment. For information on Clustered NFS in a Serviceguard Storage Management Suite
environment, see Serviceguard NFS Toolkit Support for Cluster File System available at:
www.hp.com/go/hpux-serviceguard-docs → HP Serviceguard NFS Toolkit → White papers
Common internet file system (CIFS) support
Chapter 6 in the Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide
discusses the Common Internet File System (CIFS), but it is not relevant in a Serviceguard Storage
Management Suite environment. For information on CIFS in a Serviceguard Storage Management
Suite environment, see HP CIFS Server Administrator's Guide, April 2011 (p/n 5900-1282)
