Hardware Management Console; Ipl Flow With An Hmc Attached To The System - IBM OpenPower 720 Technical Overview And Introduction

Boot to server firmware:
Select the state for the server firmware: Standby or Running.
When the server is in the server firmware standby state, partitions can be set up and
activated

2.11.2 Hardware Management Console

Depending on the model, the HMC provides a number of native serial ports and Ethernet
port. One serial port can be used to attach a modem for the Service Agent. The Service
Agent Connection Manager can be used instead if the HMC has a TCP/IP port 80 connection
to the Internet. The HMC provides an Ethernet port (or ports) to connect to partitions on its
POWER5 processor-based managed systems. The network connection is mandatory for the
HMC to OpenPower systems, and highly recommended between the HMC and partitions. It
supports the following functions:
Logical partition configuration and management
Dynamic logical partitioning
Capacity and resource management
System status
HMC management
Service functions (for example, Microcode Updates and Service Focal Point)
Remote HMC interface
Note: The same HMC cannot be attached to POWER4 and POWER5 processor-based
systems simultaneously, but for redundancy purposes, one POWER5 processor-based
server can be attached to two HMCs.
All the managed servers must be authenticated from the HMC. If a new attached system is
discovered, the HMC will prompt you to set two passwords using the HMC interface:
Advanced System Management general user ID password
Advanced System Management admin ID password
HMC access password

2.11.3 IPL flow with an HMC attached to the system

When the system status is in standby, you can use the HMC to open a virtual terminal and
access the SMI, or launch a Web browser to access the ASMI.
Using the SMI or the ASMI, you can view or modify the proper IPL settings in order to set the
boot mode to partition standby and then turn the system on. However, the HMC can be also
used to power on the managed system (and is highly recommended). Using the HMC to turn
the system on requires you to select one of the following choices:
Partition Standby
– The Partition Standby power-on mode allows you to create and activate logical
partitions.
– When the Partition Standby power-on is completed, the operator panel on the
managed system displays LPAR..., indicating the managed system is ready for you to
use the HMC to partition its resources and, possibly, activate them.
