Command Line Switches

Several command line switches are available to modify the standard behavior of the Compaq ADD driver. The syntax of the command line switches is:

1./PERF:[memory blocks]

This command line switch is a non-standard switch implemented for the CPQARRAY.ADD to modify the performance characteristics of the driver when using a Smart Array 3200 Controller. Under heavy disk use, this command switch enables greater performance based on the number associated with the [memory blocks] parameter. The larger the [memory blocks] parameter, the better the performance under heavy disk use. When you increase this parameter, the CPQARRAY.ADD driver will use more memory.

BASEDEV=CPQARRAY.ADD /PERF:[memory blocks]

[memory blocks] is number in the range of 3 to 9 that indicates the amount of memory blocks allocated per Smart Array 3200 Controller in the system. The driver runs at a default value of 5. Use this formula to determine the amount of memory being used:

Number of Smart Array 3200 Controllers * [memory blocks] * 64 KB

Example:

BASEDEV=CPQARRAY.ADD /PERF:6

2./V

The Verbose mode command line switch is a standard command line switch which causes the driver to print information to the screen when it loads. The driver identifies itself with the current revision. Then information concerning the adapters and the drives attached to them displays. Adapter information includes IRQ, slot number, and controller order number. Drive information includes physical and logical drive count and the geometry information for each logical drive.

Example:

BASEDEV=CPQARRAY.ADD /V
