The standby phase components are as follows:v Modem ConfigurationThe service processor configures the modem (if installed) so that incoming calls can be received, oroutgoing calls can be placed.v Dial InMonitor incoming phone line to answer calls, prompt for a password, verify the password, and remotelydisplay the standby menu. The remote session can be mirrored on the local HMC virtual terminalwindow if the system is so equipped and if the user enables this function.v MenusThe service processor menus are password-protected. Before you can access them, you need eitherthe general user-password or privileged-user password.Service processor menus are available on ASCII terminals attached to the serial ports on the system,and on terminal emulators. On HMC-managed systems, service processor menus are also available onthe HMC interface.Bring-Up PhaseOn a system that is powered-on to full system partition, this phase is entered upon power-on, and exitedupon loading of the operating system.On a system that is powered-on to partition standby, this phase is entered upon power-on, and exitedwhen the partition manager and hypervisor have been loaded and become fully operational in systemmemory. The end of this phase is indicated by LPAR on the operator panel. At this point, the server canstart multiple logical partitions that would be activated through the HMC interface.The bring-up phase components are as follows:v Retry Request CheckThe service processor checks to see if the previous boot attempt failed. If the specified number offailures are detected, the service processor displays an error code and places an outgoing call to notifyan external party if the user has enabled this option.v Dial OutThe service processor can dial a preprogrammed telephone number in the event of an IPL failure. Theservice processor issues an error report with the last reported IPL status indicated and any otheravailable error information.v Update Operator PanelThe service processor displays operator panel data on the HMC virtual terminal window if a remoteconnection is active.v Environmental MonitoringThe service processor provides expanded error recording and reporting.v System Firmware Surveillance (Heartbeat Monitoring)The service processor monitors and times the interval between system firmware heartbeats.v Responding to System Processor CommandsThe service processor responds to any command issued by the system processor.Chapter 7.
