Standby Phase
The standby phase can be reached in either of two ways:
v
With the server off and power connected (the normal path), recognized by
OK
in the LCD display.
OR
v
With the server on after an operating system fault, recognized by an 8-digit code in the LCD display.
In the standby phase, the service processor takes care of some automatic duties and is available for
menus operation. The service processor remains in the standby phase until a power-on request is
detected.
The standby phase components are as follows:
v
Modem Configuration
The service processor configures the modem (if installed) so that incoming calls can be received, or
outgoing calls can be placed.
v
Dial In
Monitor incoming phone line to answer calls, prompt for a password, verify the password, and remotely
display the standby menu. The remote session can be mirrored on the local HMC virtual terminal
window if the server is so equipped and if the user enables this function.
v
Menus
The service processor menus are password-protected. Before you can access them, you need either
the general user-password or privileged-user password.
Service processor menus are available on ASCII terminals attached to the serial ports on the primary
I/O book, and on terminal emulators. On HMC-managed systems, service processor menus are also
available on the HMC graphical user interface.
Bring-Up Phase
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:
v
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.
v
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.
v
Update Operator Panel
The service processor displays operator panel data on the HMC virtual terminal window if a remote
connection is active.
v
Environmental Monitoring
The service processor provides expanded error recording and reporting.
v
System Firmware Surveillance (Heartbeat Monitoring)
