Managing Superdome Complexes: A Guide for HP-UX System Administrators

Configuring and Managing Superdome Partitions
Overview of Superdome Partition Concepts
Chapter 4118
An inactive partition is in a ready-for-reconfig state, and thus all cells
in the partition are in a boot-is-blocked state at a cell firmware level.
When managing and configuring partitions, you can reconfigure all
features of the local partition. You also can reconfigure all features of
remote partitions that are inactive.
You can modify many partition attributes for remote partitions that are
active, but you cannot add or remove cells from active remote partitions.
Use the parstatus -P HP-UX command to list all partitions and their
boot states (active or inactive).
To make a partition inactive, put the partition into a ready-for-reconfig
state. You can accomplish this by using the BCH interface’s
RECONFIGRESET command, by using the GSP command menu’s RR
command, or by using either of the following HP-UX commands:
shutdown -R -H or reboot -R -H,
If using the GSP command menu’s RR command, you should ensure that
the partition is not running HP-UX. First shut down HP-UX before
issuing the RR command.
See Chapter 5 for details on booting and resetting partitions.
Types of Cells For the HP-UX 11i release on Superdome servers, all cells within a
partition are base cells that belong only to the partition to which they
are assigned. (Future releases may support additional types of cells.)
When creating partitions and assigning cells to partitions using
HP-UX 11i utilities, you must specify that the cells are base cells.
One of the cells in each partition must serve as the active core cell. The
core cell is a cell that is connected to an I/O chassis with a core I/O card
in PCI card slot 0. This core cell serves as a monarch cell that controls
the partition until HP-UX is booted. The core cell’s core I/O card is used
and a processor on the core cell runs the Boot Console Handler (BCH)
code while all other processors are idle until HP-UX is booted.
