Step-by-Step Cluster Conversion
HP-UX Configuration
Chapter 3112
HP-UX Configuration
A correct HP-UX configuration ensures that all cluster nodes provide the
environment and system configuration required to run SAP Application
Server based business scenarios.
Several of the following steps must be repeated on each node. Record the
steps completed for each node, as you complete them. This helps identify
errors in the event of a malfunction later in the integration process. The
HP-UX configuration task is split into the following sections:
• Directory Structure Configuration - This section adds
implementation practices to the architectural decisions made in the
chapter “Storage Layout Considerations”. It gives some guidance
how to achieve the differences in directory structure layout for a
clustered SAP system as compared to a standard installation.
NOTE Most of these steps in this section are only performed once on the
primary host.
The primary host is where the SAP Instance was installed. If your
database is currently running on a machine different from this, the
database vendor dependent steps will have to be done on the host on
which the database was installed.
• Cluster Node Synchronization - There are a couple of changes to
the operating system configuration that were performed during SAP
installation on the primary node. In order to allow the system to run
on other nodes, these changes need to be made to other cluster nodes,
too. This section also includes steps to distribute the changes of the
directory structure configuration performed in the section above.
NOTE Repeat the cluster node synchronization steps for each node of the
cluster that is different than the primary.
