Powering Cells and I/O Chassis On and Off
HP System Partitions Guide: Administration for nPartitions, rev 5.1 317
You cannot power off active cells or power on or off cells assigned to a
remote nPartition when using frupower.
To power on or off an I/O chassis using frupower, do so by power cycling
the cell to which it is connected.
Step 1. Login to HP-UX running on one of the system’s nPartitions.
To manage a cell’s power, you must login to the nPartition to which the
cell is assigned. If the cell is not assigned to an nPartition, you can
manage its power from any nPartition.
Step 2. Use the frupower command to turn on or turn off the cell’s 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.
