Controller Ordering - Compaq Smart Array 221 User Manual

Controller Ordering

There are two factors that determine controller ordering under IBM OS/2:
1. The order in which the ADD driver appears in the CONFIG.SYS file
determines how each type of controller is ordered relative to other types
of controllers.
Each type of controller that a single ADD driver controls is grouped
together. 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.
The slot in which the controller is installed does not affect the loading
order; only the order shown in CONFIG.SYS affects the order.
2. Each ADD driver developed by Compaq orders its controllers in
ascending order based on the controller order assigned by the Compaq
System Configuration Utility.
The following rules must be followed for the driver to function properly with
other storage controllers configured in the system.
NOTE: These rules are NOT automatically enforced by the Compaq System
Configuration Utility. Follow them carefully when configuring the system.
1. All Compaq array controllers should be in consecutive order as a group.
If booting from a Compaq Smart Array 221 Controller, the
CPQARRAY.ADD must be present and the IBM1S506.ADD driver must
not be present in CONFIG.SYS.
2. If a Compaq IAES Controller is the only other controller installed in the
system, since it cannot be primary, the system must boot from the
Compaq Smart Array 221 Controller (controller order = First).
