Serviceguard Version A.11.16 Release Notes, Second Edition
What’s in this Version
Chapter 112
— Full Admin: Includes Monitor and Package Admin privileges.
This user can issue commands to administer the cluster. It is
defined in the cluster configuration file.
On the command line, users can issue the cmhaltcl, cmruncl,
cmhaltnode, and cmrunnode commands.
In the graphical user interface, these menu choices are offered:
run or halt a cluster, run or halt a node, and run or halt a System
Multi-node Package.
Configuring
Configuration still requires root permission (UID=0) on a cluster node.
Root users do not need an Access Control Policy. On the command line,
you must log in as root to a node. In Serviceguard Manager, you will be
prompted for a root password when you begin configuration.
Now you can do configuration through Serviceguard Manager,
Serviceguard’s graphical user interface. With the new configuration
capabilities, Serviceguard Manager has replaced the functionality of the
SAM Cluster tool; the tool no longer appears in SAM.
Serviceguard Manager is available free from software.hp.com, and is
delivered on the Distributed Components CD that comes free with
Serviceguard. For more information, see the Serviceguard Manager

Network Failure Detection
A new cluster configuration parameter, Network Failure Detection, now
offers two choices for detecting when a LAN card is down:
• INOUT, the present method is the default. With this method, the
Network Manager polls between cards, and watches the message
count. It will declare a card down only if both the inbound and
outbound count stops. Then it will attempt failover.
• INOUT_OR_INONLY, the new method, includes INOUT, so it will
declare a card down if both the inbound and outbound count stops. It
also adds INONLY, which will also declare a card down, if only the
inbound traffic count stops. It will attempt failover in either case.
