Determining the dominant operating system
How to determine the dominant operating system.
The operating system is a collection of system programs that control the overall operation of the system. IBM® i is an example of such an operating system. Systems can run one or more operating systems. When there is more than one operating system, IBM i is the dominant operating system.
The hardware service manager function (under Start
a Service Tool) indicates which operating system is dominant on the
system. The Release field on the Hardware Service Manager display
or printout shows the following values:
- 0
- Unknown
This indicates that an alternate IPL was performed.
- 1
- IBM i is dominant
This indicates that either IBM i is the only operating system installed, or that more than one operating system is installed (and IBM i is dominant).
For more information on the hardware service manager function, see Hardware service manager.
