How to Deconfigure a Device Manually
Before You Begin
To support the ability to boot even when nonessential components fail, the
OpenBoot firmware provides the asr-disable command, which lets you manually
deconfigure system devices. This command “marks” a specified device as disabled,
by creating an appropriate “status” property in the corresponding device tree node.
By convention, UNIX will not activate a driver for any device so marked. For
background information, see
“About Manually Configuring Devices” on page 59
What to Do
1. At the system ok prompt, type:
where the device-identifier is one of the following:
Any full physical device path as reported by the OpenBoot show-devs command
Any valid device alias as reported by the OpenBoot devalias command
An identifier for a device given in “Reference for Device Identifiers” on page 61
Note Manually deconfiguring a single processor causes the entire CPU/Memory
board to be deconfigured, including all processors and all memory residing on the
board.
OpenBoot configuration variable changes take effect after the next system reset.
