Customizable Message of the day
The HMC provides both a graphical interface and command-line interface (CLI) for all
management tasks. Remote connection to the HMC using a web browser (as of HMC
Version 7; previous versions required a special client program called WebSM) is possible.
The CLI is also available by using the Secure Shell (SSH) connection to the HMC. It can
be used by an external management system or a partition to remotely perform many
HMC operations.
2.12.2 HMC connectivity to the POWER7 processor-based systems
POWER5, POWER5+, POWER6, POWER6+, and POWER7 processor technology-based
servers that are managed by an HMC require Ethernet connectivity between the HMC and
the server’s Service Processor. In addition, if Dynamic LPAR, Live Partition Mobility, or
PowerVM Active Memory Sharing operations are required on the managed partitions,
Ethernet connectivity is needed between these partitions and the HMC. A minimum of two
Ethernet ports are needed on the HMC to provide such connectivity. The rack-mounted
7042-CR5 HMC default configuration provides four Ethernet ports. The deskside 7042-C07
HMC standard configuration offers only one Ethernet port. Be sure to order an optional PCIe
adapter to provide additional Ethernet ports.
For any logical partition in a server it is possible to use a Shared Ethernet Adapter that is
configured via a Virtual I/O Server. Therefore, a partition does not require its own physical
adapter to communicate with an HMC.
