Managing HP Serviceguard A.11.20.20 for Linux, May 2013

E Using Serviceguard Manager
HP Serviceguard Manager is a web-based, HP System Management Homepage (HP SMH) tool
that replaces the functionality of the earlier Serviceguard management tools. Serviceguard Manager
allows you to monitor, administer and configure a Serviceguard cluster from any system with a
supported web browser.
The Serviceguard Manager Main Page provides you with a summary of the health of the cluster
including the status of each node and its packages.
See the Release Notes for your version of Serviceguard for Linux for information about the latest
release of Serviceguard Manager, as well as installation and configuration instructions.
E.1 About the Online Help System
Once Serviceguard Manager is running, use the Serviceguard Manager tooltips by moving your
mouse over a field from the read-only property pages for a brief definition for each field. You can
also open the online help by clicking the button in the upper-right hand corner of the screen.
Start with the help topic “Understanding the HP Serviceguard Manager Main Page”. You should
also read the help topic “About Security”, as it explains HP Serviceguard Manager Access Control
Policies, as well as root privileges.
E.2 Launching Serviceguard Manager
This section provides information about two common scenarios.
TIP: To prevent an Out of Memory error reported by Tomcat (Exception in thread "main"
java.lang.OutOfMemoryError: Java heap space), which may occur especially if the
server is under heavy load or Serviceguard Manager is managing a large cluster (4 nodes with
300 packages), do the following from the command line:
1. Stop hpsmhd
/etc/init.d/hpsmhd -stop
2. Modify the /opt/hp/hpsmh/tomcat/bin/startup.sh file, and add the following line
in the export statements section:
export CATALINA_OPTS="-Xms512m -Xmx512m"
3. Save the file and restart hpsmhd
/etc/init.d/hpsmhd -start
E.2.1 Scenario 1 - Single cluster management
Scenario 1 applies if you are:
• Managing a single cluster, and
• Have installed Serviceguard version A.11.19 or later.
NOTE: SMH access roles constrain a user's cluster-management capabilities:
• A user with HP SMH Administrator access has full cluster management capabilities.
• A user with HP SMH Operator access can monitor the cluster and has restricted cluster
management capabilities as defined by the user’s Serviceguard role-based access configuration.
• A user with HP SMH User access does not have any cluster management capabilities.
