Managing the Overall Complex
Detecting / Controlling Power in the Complex

HP-UX Commands Use this procedure to power on or power off cells (and their associated
I/O chassis) using HP-UX commands.
When using HP-UX commands to manage power, you are restricted to
powering on or off inactive cells that are either assigned to the local
partition or are not assigned to a partition.
You cannot use HP-UX commands to manage the power of active cells or
cells assigned to a remote partition. 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. Log in to HP-UX running on one of the Superdome complex’s partitions.
To manage a cell’s power you must log in to the partition to which the cell
is assigned.
If the cell is not assigned to a partition, you can manage its power from
any partition.
Step 2. Use the frupower command to turn on or turn off the cell’s power.
Specify the frupower -f option to power off a cell. This also powers off
any I/O chassis connected to the cell.
Specify the frupower -o option to power on a cell. This also powers on
any I/O chassis connected to the cell.
The example that follows shows several sample frupower commands
and their results.
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 partition (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.
# 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.
