You can power on or power off cells and I/O chassis by
using any one of the following procedures:
You can control power for cells and I/O chassis from remote
locations, without physically accessing the system hardware.
The frupower command and Partition Manager
permit you to power on or off inactive cells and I/O chassis that are assigned
to the current nPartition or are not assigned to any nPartition.
The PE command at the service processor
Command menu permits you to power on or off any hardware in the complex, including
active cells and I/O chassis. The PE command does not check
the current usage of components.
Procedure 7-3 Powering Cells and I/O Chassis On and Off (Service Processor)
Use the Command menu PE command
to power on and power off cells, I/O chassis, and cabinets from the service
processor interface (GSP or MP).
You can manage the power for all components within the
server complex by using the PE command at the service processor
Command menu, regardless of any nPartition assignment or the status (active
or inactive) for the hardware components.
Login to the
service processor for the server and access the Command menu.
From the service processor Main menu, enter CM to
access the Command menu. To exit the Command menu enter MA.
Issue the PE command
and specify the type of hardware whose power you want to turn on or turn off.
You can manage power to cells, I/O chassis, and cabinets.
Specify the hardware
device to power on or power off.
The service processor
does not check whether the specified component is currently being used.
Cabinets—When you power on or off
a cabinet, the firmware also powers on or off all cells and I/O chassis in
Cells—When you power on or off a
cell, the firmware also powers on or off any I/O chassis attached to the cell.
When specifying a cell, you indicate both the cabinet number
and the slot in which the cell resides.
I/O Chassis—When you power off an
I/O chassis from the service processor Command menu, the system firmware resets
the cell attached to the I/O chassis (if the cell located and mapped the I/O
chassis during its cell boot process).
an I/O chassis, you indicate the cabinet, bay, and chassis numbers to identify
In the following example, the service processor powers
off cell 2 in cabinet 0.
This command controls power enable to a hardware device.
B - Cabinet
C - Cell
I - IO Chassis
Select Device: c
Enter cabinet number: 0
Enter slot number: 2
The power is ON for the Cell in Cabinet 0, Slot 2.
In what state do you want the power for the
Cell in Cabinet 0, Slot 2? (ON/OFF) OFF
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).
Login to a system
with the nPartition commands installed.
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.
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
When using Partition Manager Version 1.0, select an inactive
cell or I/O chassis, and use the CellPower
Off Cell or I/OPower 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 CellPower
Off Cell or I/OPower Off Chassis action (or a similar
"Power On..." action).
For details on accessing Partition Manager
or other tools, see “Tools for Managing Hardware”.
Select the cell
or I/O chassis you want to power on or off.
Manager Version 1.0, select the nPartition containing the item you want to
power on or off, then select the item.
In Partition Manager Version 2.0, select the cell (or I/O
chassis) that you want to power on or off.
Select the Partition
Manager action to power on or off the selected item.
the CellPower On Cell action, or select the CellPower
Off Cell action. If powering on or off an I/O chassis,
instead use the I/OPower On... or I/OPower Off... actions.
From Partition Manager Version 1.0, select
the FileExit action.
From Partition Manager Version 2.0, select Log
off parmgr or exit the Web browser when finished.
