Standalone diagnostics (POWER® processor-based systems only)

Standalone diagnostics provide a method to test the system when the online diagnostics are not installed and a method of testing the disk drives that cannot be tested by the online diagnostics.

Standalone diagnostics are currently packaged on CDROM. They are run by placing the Standalone Diagnostic CDROM into the cdrom drive, then booting the system in service mode.

The Standalone Diagnostic CDROM file system is mounted over a RAM-file system for execution. Because of this, the CDROM drive (and the SCSI controller that controls it) cannot be tested by the standalone diagnostics.

Device support that is not on the Diagnostic CDROM must be supported by Diagnostic Supplemental Media.
