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.

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

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.

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

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.
