Controller Ordering
Two factors determine controller ordering in a system operating in an
IBM OS/2 environment:
■ The order of ADD drivers specified in the CONFIG.SYS file determines
the order of types of controllers relative to other types of controllers.
A single ADD driver groups all of the controllers in its array together.
Among a group of ADD drivers, the first ADD driver to appear in the
CONFIG.SYS file has its controllers ordered first, the second ADD
driver has its controllers ordered after the first driver controller, and so
on.
Only the order shown in CONFIG.SYS affects the order. The slot in
which the controller is installed does not affect the loading order.
■ Each ADD driver developed by Compaq orders its controllers in
ascending order based on the controller order assigned by the Compaq
System Configuration Utility.
Use the following rules to ensure proper controller functioning and ordered
interaction with other storage controllers in the system.
NOTE: The Compaq System Configuration Utility does not automatically enforce the
recommended array configuration rules. Follow these rules carefully when you manually
configure the system.
■ Compaq array controllers should be stored in consecutive order as a
group.
■ When you boot from the Compaq Integrated Smart Array Controller, the
statement BASEDEV = CPQARRAY.ADD must be present in
CONFIG.SYS.
