8.23 CAPPING (Display or set CPU capping value)

8.23.1 Function

The CAPPING command displays or sets the CPU capping value. If mips is greater than zero then the
CPUs are capped to this value. If mips is equal to zero or “OFF” then the capping is disabled.

Only CPUs of type CP are capped. CPUs of type IL, AP or IP are never capped. The CPU string on the
Hercules device and status panel which shows the CPU usage turns from white to red during the time the
CPU is capped.

8.23.3 Parameter

mips

Maximum total number of MIPS for all the ‘CP’ type processors.

OFF

Disables the CPU capping.

0

This is the same as OFF.

8.23.4 Examples

Example 1:

Display the current CPU capping value (capping set).

HHC00013I Herc command: 'capping'

HHC00832I Central processors will be capped at 10 MIPS

Example 2:

Set the CPU capping value to 25 MIPS.

HHC00013I Herc command: 'capping 25'

HHC00877I Central processors are capped at 25 MIPS

Example 3:

Disable the CPU capping.

Example 4:

Display the current CPU capping value (capping not set).

HHC00013I Herc command: 'capping'
