HP Instant Capacity (iCAP) guide

Instant Capacity and Reinitializing the nPartition (Genesis Partitions)

Any use of the CC command at the service processor level has the potential to overwrite the Instant Capacity configuration, and is therefore not recommended on Instant Capacity systems. In particular, creating a Genesis Partition on an Instant Capacity system is not recommended because it causes the system to be out of compliance.

If you clear the configuration of a system that has Instant Capacity components (components without usage rights), you must acquire and apply a codeword that restores a lost iCAP configuration to remain in compliance with your contract. Because the codeword can be generated only by using a recent audit snapshot of the system, generate an audit snapshot with icapstatus -sbefore doing the reset or, if asset reporting is configured, make sure that a recent asset report was sent to the portal.
