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
