Offline Configuration and Activation of Processors
Operating in Offline Activation Mode
Appendix A112
System state:
• The system is booted
• One or more processors are deconfigured
• No processors are deactivated by iCOD software
Procedure:
Step 1. Reboot the system and stop the boot process at BCH
Step 2. At BCH, configure processors per configuration rules
Step 3. Boot the system (iCOD software deactivates the previously deconfigured
processors)
Step 4. At any time after this, you can use icod_modify -a to instantly activate
the newly configured processors
NOTE Following this procedure results in the application running in an
environment with deactivated processors. System state information
reflects the deactivated processors, but is different than that reported by
a non-iCOD system. Some applications may notice the difference, but
most do not. This approach provides the intended level of flexibility for
those customers and applications that have been verified to work with
deactivated processors present on a system.
