Booting and Resetting Superdome Partitions
Overview of Partition Booting Concepts and Issues
Chapter 5 227
Ready-for-Reconfig State—Shuts down a partition, performs any
partition reconfigurations, and keeps all cells at a boot-is-blocked
(BIB) “cell firmware” state, thus making the partition and all of its
cells inactive. When a partition is in a ready-for-reconfig state, you
can reconfigure (or remove) the partition from a remote partition.
All cells—including any inactive cells and all newly added or deleted
cells—reboot and are reconfigured, and all cells remain at BIB.
You can put a partition into a ready-for-reconfig state by using the
shutdown -R -H or reboot -R -H command, using the BCH
interface’s RECONFIGRESET command, or using the GSP command
menu’s RR command.
When rebooting a partition under normal circumstances (when not
reconfiguring or halting the partition) use the shutdown -r or
reboot -r commands.
Superdome Booting Features
This section provides an overview of several new boot issues for
HP Superdome servers.
On HP Superdome servers each partition is booted, rebooted, shut down,
and reset individually.
In most cases you will boot and reboot Superdome partitions using the
same basic procedures that are used on other HP 9000 servers.
The following list describes several new issues related to booting,
rebooting, and power cycling partitions on HP Superdome servers:
HP Superdome server resources (cells and I/O chassis) are configured
into one or more partitions, each of which can boot a single instance of
HP-UX. Each partition can boot and reboot independently of others.
All of a partition’s cells and I/O chassis must be powered on and
active in order to contribute resources to the partition.
You can perform all reset and power cycling tasks remotely.
Superdome server cabinets do not have TOC or reset switches.
Instead, you issue TOCs using a Guardian Service Processor (GSP)
command and issue resets using GSP commands or BCH interface
commands. Use caution when resetting or sending a TOC
