PRIMECLUSTER Installation and Administration Guide 4.2 (Linux for Itanium)

A.6 Kernel Parameter Worksheet

When you build the PRIMECLUSTER system, the default values for the kernel parameters of the Linux(R) may be inadequate. The Kernel Parameter Worksheet shows the kernel parameter values used for PRIMECLUSTER. If the values have been set in /etc/sysctl.conf, you need to edit the values (Defined values + kernel parameter values used for PRIMECLUSTER). If the values have not been set, you need to set the values (Linux(R) default values + the kernel parameter values used for PRIMECLUSTER.)

The kernel parameter values differ depending upon:

• CF configuration

• RMS configuration

• Using GFS

• The values used by products and user applications that operate in the PRIMECLUSTER system must also be included in the kernel parameter values.

• To enable values that have been changed, you must restart the system after the installation.

• If a kernel parameter value is already maximized, the change will not be added to the system.
