nPartition Administrator's Guide, Second Edition

Procedure 7-4 Powering Cells and I/O Chassis On and Off (nPartition Commands)
From the command line, use the frupower -o -c# and frupower -f -c# commands to
power on and power off cells (and their associated I/O chassis).
NOTE: You can remotely perform this task using remote administration options supported by
the Enhanced nPartition Commands or Partition Manager Version 2.0. Remote administration
is supported by the Partition Manager Tools→Switch Complexes action and by the nPartition
command -u... -h... options or -g... -h... options.
For details see “Tools for Managing Hardware” (page 201).
1. Login to a system with the nPartition commands installed.
To manage power for a cell, you must login to the nPartition to which the cell is assigned
or use the Enhanced nPartition Commands remote administration features.
If the cell is not assigned to an nPartition, you can manage its power from any nPartition or
from a remote system.
2. Use the frupower command to turn on or turn off the cell power.
Specify the frupower -f -c# command to power off a cell. (-c#). This also powers off
any I/O chassis connected to the cell.
Specify the frupower -o -c# command to power on a cell (-c#). This also powers on any
I/O chassis connected to the cell.
The following example shows several sample frupower commands and their results.
# frupower -f -c0
Error: Can not power off active cell 0.
# frupower -f -c2
# frupower -o -c2
# frupower -f -c6
Error: Cell 6 belongs to partition 1. Can not power off cell.
#
# frupower -f -i0/1/1
Error: I/O chassis 0/1/1 is attached to a powered-on free
cell 4. Please power off the free cell.
#
In the above example, cell 0 is active and thus cannot be powered off using frupower. Cell
2 is inactive and is powered off (frupower -f -c2) and then powered back on (frupower
-o -c2). Cell 6 is assigned to a remote nPartition (partition number 1) and thus cannot be
powered off. I/O chassis 0/1/1 is attached to cell 4, so to power it off cell 4 must be powered
off.
Procedure 7-5 Powering Cells and I/O Chassis On and Off (Partition Manager)
You can power cells and I/O chassis on and off by using Partition Manager.
When using Partition Manager Version 1.0, select an inactive cell or I/O chassis, and use the
Cell→Power Off Cell or I/O→Power Off I/O Chassis action (or a similar "Power On..." action)
When using Partition Manager Version 2.0, select an inactive cell or I/O chassis, and use the
Cell→Power Off Cell or I/O→Power Off Chassis action (or a similar "Power On..." action).
