nPartition Administrator's Guide, Second Edition

frupower Command
The frupower command turns on, turns off, or displays the current status of power for cells
and I/O chassis in cell-based servers.
Root permission is required to run this command.
• By default, the frupower command permits you to power on or off inactive cells and I/O
chassis that either are assigned to the target nPartition or are not assigned to any nPartition.
• I/O chassis power is turned on or off when the cell to which it is connected is powered on
or off. However, you also can control I/O chassis power separately from cell power in certain
situations.
— You can turn on I/O chassis power when a powered-off I/O chassis is attached to an
active cell assigned to the target nPartition. The nPartition must be rebooted for the
power on to become effective.
— You can turn off I/O chassis power when the I/O chassis is not assigned to an nPartition
and (on HP Integrity Superdome servers) when nPartition Configuration Privilege is
unrestricted.
• When using the Original nPartition Commands, the target and local nPartition are the same.
When using the Enhanced nPartition Commands, the target nPartition may be different
from the local nPartition when the -u... -h... options are specified.
CAUTION: When using the Enhanced nPartition Commands, the frupower -g... -h...
command and options allow all power operations on all cells and I/O chassis in the target complex,
even if this results in turning power off for a component of an active nPartition.
NOTE: On servers based on the HP sx1000 chipset or HP sx2000 chipset, you cannot turn cell
or I/O chassis power on or off for free cells or I/O chassis when nPartition Configuration Privilege
is restricted and when not using the -g... -h... options.
The nPartition Configuration Privilege setting does not affect the ability to control power using
the frupower -g... -h... command and option.
Command syntax and options for frupower follow. Refer to the frupower(1M) manpage for
details.
Syntax
frupower [ -d | -o | -f ] -c cell [-c...]
frupower [ -d | -o | -f ] -i IOchassis [-i...]
frupower [-d] -C [-l cabinet] [-l...]
frupower [-d] -I [-l cabinet] [-l...]
Enhanced nPartition Commands Notes
• The -u... -h... set of options may be specified to cause the command to send its
management request using WBEM to an nPartition other than the local nPartition (but can
also be used as a "loopback access" to the local nPartition).
• The -g... -h... options may be specified to cause the command to send its management
request using IPMI over LAN to a service processor in another server complex (but can also
be used as a "loopback access" to the service processor in the local complex).
The -u and -g options are mutually exclusive.
Options
-d
Display power status of the specified cells or I/O chassis. This
is the default.
-o
Power on the specified cells or I/O chassis.
The -o and -f options are mutually exclusive. The -o and -f
options are unavailable with -C and -I.
