PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

A.5 Kernel Parameter Worksheet

When you build the PRIMECLUSTER system, the default values for the kernel parameters of the Solaris may be inadequate. The Kernel Parameter Worksheet shows the kernel parameter values used for PRIMECLUSTER.

Set up the kernel parameter as follows according to the type of "Characteristics" included in the table.

• Addition

  Specify the total of the system default value and the recommended or specified values for each software product.

• Maximum value

  Specify a maximum for the recommended or specified values for each software product.

  You must, however, use the default value if the maximum value is smaller than the system default value.

The kernel parameter values differ depending upon:

• CF configuration
• RMS configuration
• Using GFS
• Using GLS

• For details of the kernel parameters and instructions on changing parameter values, see "Solaris System Administration" in "Solaris X System Administrator Collection Vol. 1."
• For information on the default values of the Solaris, see the "Solaris Tunable Parameters Reference Manual."

• 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.
