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 -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 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.
Partition Manager This procedure (Cell —> Power On Cell menu, or Cell —> Power Off Cell
menu) powers on and powers off cells (and their associated I/O chassis)
using Partition Manager.
NOTE You can use Partition Manager to power on or off inactive cells that are
assigned to the local partition.
You cannot power off active cells or power on or off cells assigned to a
remote partition when using Partition Manager.
