Automatic System Recovery User Commands

The ALOM CMT commands are available for obtaining ASR status information and for manually unconfiguring or reconfiguring system devices. For more information, see:

■“Unconfiguring and Reconfiguring Devices” on page 35

Enabling and Disabling Automatic System Recovery

The automatic system recovery (ASR) feature is not activated until you enable it. Enabling ASR requires changing configuration variables in ALOM CMT as well as OpenBoot firmware.
