Use the parstatus -P HP-UX command to list all partitions and their
boot states (active or inactive).
To make an inactive partition active, use the service processor (GSP or
MP) Command menu’s BO command. The BO command clears the
boot-is-blocked flag for all cells assigned to the partition, thus allowing
the cells to rendezvous and enabling the partition to run the BCH
interface. (If all of an nPartition’s cells are powered off, you must power
on its cells to enable the partition to become active.)
To make a partition inactive, you can issue commands from HP-UX, the
BCH interface, or the service processor (GSP or MP) Command menu.
• When HP-UX is running on an nPartition, you can make the partition
inactive by issuing the shutdown -R -H command to shut down
HP-UX, reboot all cells, and hold all cells at a boot-is-blocked state.
• When the BCH interface is available for an nPartition, you can make
the partition inactive by issuing the BCH interface’s RECONFIGRESET
command. This reboots all cells assigned to the partition and holds all
cells at a boot-is-blocked state.
• If an nPartition is active but is not responsive (that is, if you can
neither log in as root to issue the shutdown -R -H command nor
access the partition’s BCH interface from its console), then use the
service processor Command menu’s RR command to make the
partition inactive. This reboots all cells assigned to the partition and
holds all cells at a boot-is-blocked state.
CAUTION Issuing the service processor Command menu’s RR command
immediately halts all processing and I/O activity on the specified
nPartition. Be certain to correctly specify which partition is to be reset
to a ready for reconfig state.
