These commands are provided for use when diagnosing a problem with a ‘‘live’’ system. 
Any other use may result in indeterminate conditions. 

Note: It is recommended that StorageTek support personnel be contacted before using 
diagnostic subsystem commands. 

These commands are only valid when entered from the ACS service machine’s virtual 
console. 

Issue the following SCP operator command: 

This command activates the diagnostic subsystem and enables the use of some special 
commands. 

prefixchar is a command prefix indicating that the command is to be handled by the 
diagnostic subsystem. The default prefix is ‘‘=’’ (equal sign), but may be set to any 
character that does not conflict with use by other subsystems (for example, the HSC). 

Note: The prefix character cannot be changed during a session. The SCP must be recycled 
and the new prefix character specified with the subsequent SUBSYS command. 

The commands below are part of the diagnostic subsystem. The prefix character should be 
that described above.

=DEBUG 

- enter the ‘‘debug’’ mode.

=NODEBUG 

- exit the ‘‘debug’’ mode. 

=DDICT 

- return the data dictionary definition of a field.

=HPER 

- set multiple break-points using the CP PER command. 

=WHERE 

- display the storage location for a given program module.

This diagnostic command initiates the special ‘‘debug’’ mode. ‘CP SET RUN OFF’ is also 
executed.

the command character for the DIAG subsystem.  The default is ‘‘=’’, but may be set 
to any character by the SUBSYS command that started the subsystem.
