IBM P5 570 - Manual (Page 56)

44 p5-570 Technical Overview and Introduction
– Boot to open firmware prompt
– Boot to System Management Service (SMS) to further select the boot devices or
network boot options
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 several native serial ports and Ethernet ports.
One serial port may be used to attach a modem for Service Agent. 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 managed
POWER5 processor-based systems. The network connection is mandatory for the HMC to p5
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
All 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 system status is standby, you can either 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, but 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 selecting one of the following:
Partition Standby
The Partition Standby power-on mode enables you to create and activate logical
partitions.
Note: The same HMC cannot be attached to POWER4 and POWER5 processor-based
systems simultaneously, but for redundancy purposes one POWER5 server can be
attached to two HMCs.
