Information

automatic system recovery (ASR) feature.
● At the ok prompt, type:
In the .asr command output, any devices marked disabled have been manually
unconfigured using the asr-disable command. The .asr command also lists
devices that have failed firmware diagnostics and have been automatically
unconfigured by the OpenBoot ASR feature.
For more information, see:
■ “Automatic System Recovery” on page 41

Unconfiguring and Reconfiguring
Devices
To support a degraded boot capability, the OpenBoot firmware provides the
asr-disable command, which enables you to unconfigure system devices
manually. This command “marks” a specified device as disabled, by creating an
appropriate status property in the corresponding device tree node. By convention,
the Solaris OS does not activate a driver for any device so marked.
▼ To Unconfigure a Device Manually
1. At the ok prompt, type:
ok .asr
ok asr-disable device-identifier
