To load standalone diagnostics , press the 5 key on the HMC.
To load the online diagnostics press the 6 key on the HMC. The service mode boot list is loaded. Like
the default boot list, the service mode boot list can contain several entries.
Note: The 6 key works like the 5 key with the following exceptions:
v The system searches for a boot record according to the service mode boot list.
v
If the service mode boot list is discovered by a cyclical redundancy check to be corrupted, the
system rebuilds the service mode boot list according to the default boot list. (The default boot list
contains five entries, and for each matching device type found in the system unit, the system
makes an entry in the service mode boot list.)
v
If no service mode boot list is present, the system uses the default boot list.
