Service Processor (GSP or MP) Features
The service processor (GSP or MP) utility hardware is an independent
support system for nPartition servers. It provides a way for you to
connect to a server complex and perform administration or monitoring
tasks for the server hardware and its nPartitions.
The main features of the service processor include the Command menu,
nPartition consoles, console logs, chassis code viewers, and partition
Virtual Front Panels (live displays of nPartition and cell states). For
details see the Summary of Main Service Processor Features on page 89.
The service processor is available when its cabinet has standby power,
even if the main (48-volt) cabinet power switch is turned off.
Access to the service processor is restricted by user accounts. Each user
account is password protected and provides a specific level of access to
the server complex and service processor commands.
Multiple users can independently interact with the service processor
because each service processor login session is private. However, some
output is mirrored: the Command menu and each nPartition console
permit one interactive user at a time and mirror output to all users
accessing those features. Likewise, the service processor mirrors live
chassis codes to all users accessing the Live Chassis Logs feature.
Up to 16 users can simultaneously log in to the service processor through
its network (customer LAN) interface and they can independently
manage nPartitions or view the server complex hardware states.
Two additional service processor login sessions can be supported by the
local and remote serial ports. These allow for serial port terminal access
(through the local RS-232 port) and external modem access (through the
remote RS-232 port).
In general, the service processor (GSP or MP) on nPartition servers is
similar to the service processor on other HP servers, while providing
enhanced features necessary for managing a multiple-nPartition server.
For example, the service processor manages the complex profile, which
defines nPartition configurations as well as complex-wide settings for the
server.
