nPartition Administrator's Guide, Second Edition

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 (or the Live Events feature).
Up to 32 users can simultaneously login 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 (MP or GSP) on cell-based servers is similar to the service
processor on other HP servers, while providing enhanced features necessary for managing a
multiple nPartitions.
For example, the service processor manages the complex profile, which defines nPartition
configurations as well as complex-wide settings for the server.
The service processor also controls power, reset, and TOC capabilities, displays and records
system events (or chassis codes), and can display detailed information about the various internal
subsystems.
Service Processor (MP or GSP) Features
The following list describes the primary features available through the service processor on
cell-based HP servers.
• Command Menu The Command menu provides commands for system service, status, and
access configuration tasks.
To enter the Command menu, enter CM at the service processor Main menu. To exit the
service processor Command menu, enter MA or type ^b (Control-b) to return to the service
processor Main menu.
See “Command Reference for Service Processor Commands” (page 80) for details.
Service processor commands are restricted based on the three levels of access: Administrator,
Operator, and Single Partition User. See “Service Processor Accounts and Access Levels”
(page 69) for details.
• Consoles Each nPartition in a server complex has its own console.
Enter CO at the service processor Main menu to access the nPartition consoles. To exit the
console, type ^b (Control-b).
See “nPartition Console Features” (page 70) for details.
Console output for each nPartition is reflected to all users currently accessing the nPartition
console.
One console user can have interactive access to each nPartition console, and all other users
of the console have read-only access. To gain write access for a console, type ^e cf (Control-e
c f).
