Disabling continuously powered main storage

 

To disable the continuously powered main storage (CPM) on the system, you can use the DisableCPM API (use the uppercase and lowercase characters as shown).

To use this command, follow these instructions:

• You must insert a key to use this command (on systems with a keystick).

This API returns the following information:

16-bit return code 0 = Command successful 1 = Command unsuccessful 2 = Key not inserted 4 = Not in Manual mode 8 = System turned On	16-bit additional data length N = 0	Not applicable
