on a system that is powered-on to full system partition, this phase is entered upon power-on, and exited upon loading of the operating system.

    on a system that is powered-on to partition standby, this phase is entered upon power-on, and exited when the partition manager and hypervisor have been loaded and become fully operational in system memory. the end of this phase is indicated when lpar displays on the operator panel. at this point, the server can start multiple logical partitions which would be activated through the hmc graphical user interface.

    the bring-up phase components are as follows:

    1 retry request check

    the service processor checks to see if the previous boot attempt failed. if the specified number of failures are detected, the service processor displays an error code and places an outgoing call to notify an external party if the user has enabled this option.

    2 dial out

    the service processor can dial a preprogrammed telephone number in the event of an ipl failure. the service processor issues an error report with the last reported ipl status indicated and any other available error information.

    1 update operator panel

    the service processor displays operator panel data on the hmc virtual terminal window if a remote connection is active.

    2 environmental monitoring

    the service processor provides expanded error recording and reporting.

    3 system firmware surveillance (heartbeat monitoring)

    the service processor monitors and times the interval between system firmware heartbeats.

    4 responding to system processor commands

    the service processor responds to any command issued by the system processor.
