• Listing Information—You can use the parstatus command or the
Partition Manager utility from any nPartition to list partition and
complex information.
• Adding (Assigning) a Cell to an nPartition—You can use parmodify
or Partition Manager from any nPartition to assign a cell to any
nPartition in the server complex.
• Removing (Unassigning) a Cell from an nPartition—You can
unassign an inactive cell from its nPartition by using parmodify or
Partition Manager on any nPartition. However, to unassign an active
cell you must use these tools from the local nPartition (the partition
to which the cell is assigned).
• Powering On or Off a Cell—To power on or off a cell that is
unassigned, you can use frupower or Partition Manager on any
partition. To power on or off an assigned cell, the cell must be inactive
and you must use frupower or Partition Manager from the local
nPartition (the partition to which the cell is assigned).
• Rebooting or Shutting Down HP-UX—To reboot or shut down HP-UX
you must issue the /usr/sbin/shutdown command and appropriate
options (such as -r, -R, -h, -R -H, or others) from the local
nPartition.
• Turning Attention Indicators (LEDs) On or Off—You can use the
fruled command or Partition Manager to control the attention
indicators for all hardware in the server complex from any nPartition.
For details refer to the complete procedures for these administration
tasks.
Active and Inactive nPartitions
Each nPartition’s boot state either is active or inactive.
An nPartition that is active has at least one cell that is active (not in a
boot-is-blocked state). When an nPartition is active, the partition’s
available cells complete partition rendezvous and then the Boot Console
Handler (BCH) interface is loaded and is displayed on the partition’s
console. HP-UX is loaded and run from BCH on an active partition.
An inactive partition is considered to be in a ready for reconfig
state, because all cells assigned to the partition either remain at a
boot-is-blocked state or are powered off.
