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.
NOTE: You must include the correct remote administration options when issuing par
commands (-h and -g for IPMI over LAN connections; -h and -u for WBEM/WMI
connections). For a complete explanation of these options, see the command description in
“nPartition Commands Reference” (page 89).
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.
Configure and deconfigure cells
You can deconfigure (make inactive) a cell that is assigned to an nPartition by setting its
use-on-next-boot value to “n” (do not use). This causes the cell to remain assigned to the nPartition,
but the cell will be inactive the next time its nPartition boots, meaning the cell hardware resources
will not be used.
Whenever you configure or deconfigure cells, you must reboot the corresponding nPartition for
the configuration change to take effect.
NOTE: Configuring and deconfiguring cells can be restricted based on any capacity on demand
(iCOD) or pay per use (PPU) contracts for the server complex.
Configure and deconfigure cells using the following procedure:
Procedure 4-47 Configuring and deconfiguring cells [nPartition commands]
From the command line, use the parmodify -p# -m#... command to configure or deconfigure
a cell by setting its use-on-next-boot attribute value. You also can use the parstatus -V -c#
command to list attribute details for a specific cell (-c# where # is the cell number).
1. Log in to Windows on the management station PC.
2. To list current cell attribute settings, use the parstatus -C command to list the
use-on-next-boot values for all cells, or use the parstatus -V -c# command to list all
attribute values for a specific cell (-c# where # is the cell number)
