DESCRIPTION [Toc] [Back]
The frupower command turns power on or off, or displays the current
status of power for cells and I/O chassis.
The operations allowed by this command are subject to the following
conditions:
+ An active cell cannot be powered off. An active cell is one that
is assigned to a partition and that is being used by the partition.
+ The -i option can be used to display the power state of any I/O
chassis, but can only control the power state of an I/O chassis in
the following two situations:
+ The I/O chassis is attached to an active cell and is powered
off. The I/O chassis may be powered on, but will not become
active until the partition to which the cell is assigned has
been rebooted.
+ The I/O chassis is attached to an active cell and is powered
on, but the I/O chassis has not yet become active. The I/O
chassis may be powered off.
+ If the target of the command is the local partition, meaning that
neither the -u nor -g option is used:
+ Any user can run the command to display the power state of cells
and I/O chassis.
+ Root permission is required to change the power state of a
component (cell or chassis).
+ Cell power operations are limited to free cells and inactive or
powered-off cells assigned to the local partition. If the

frupower(1M) frupower(1M)
nPartition Configuration Privilege is restricted, then control
of free cells is not allowed.
Note: The nPartition Configuration Privilege state can only be
changed at the service processor's Command menu.
+ When connecting to a remote partition using the -u and -h options:
+ Any local user may run the command. Root permission is not
required, and the user's system need not be an nPartition.
+ The set of allowed operations depends on the privileges of
username on the remote partition, and the state of the
nPartition Configuration Privilege on the complex on which the
remote partition exists. The rules and conditions are the same
as for the local partition description.
+ When connecting to the service processor of a complex using the -g
and -h options:
+ Any user may run the command. Root permission is not required,
and the user's system need not be an nPartition.
+ The user may display the power state of any cell or I/O chassis.
Any powered off cell can be powered on, and any inactive cell
can be powered off, whether or not the cell is assigned to a
partition or is a free cell. The state of the complex's
nPartition Configuration Privilege does not affect this mode of
command operation.
Note that knowledge of the -g passwd gives the user full
authorization to carry out any of the above operations, regardless
of her permissions on her local system.
Please refer to the HP System Partitions Guide for a description of
the partition management terms used in this man page.
Options and Arguments [Toc] [Back]
frupower recognizes the following command line options and arguments:
-d Displays power status of specified cells or I/O
chassis. This is the default.
-o Powers on specified cells or I/O chassis.
-f Powers off specified cells or I/O chassis.
The -d, -o, and -f options are mutually exclusive.
The -o and -f options are unavailable with -C and -I.

-u username:[passwd]
Specifies the required authorization to access a
partition other than the local partition and to
control components on it, subject to the conditions
stated in the DESCRIPTION section (but can also be
used as a loopback access to the local partition).
The target complex is the one in which this target
partition resides.
The -h option is required if this option is used.
username specifies a configured user name on the
target partition. Any username can display the power
state of components on the target partition. username
must have root permission to change any power state.
passwd specifies the password associated with the
username. If this field is empty, the command prompts
for the password.
Note: This command is a Web-Based Enterprise
Management (WBEM) Client Application. The -u option
accesses the target partition using a Secure Sockets
Layer (SSL) connection. If errors are reported, check
that the conditions described in the DEPENDENCIES
section are satisfied.
SECURITY WARNING: Specifying the password directly on
the command line may pose a security risk in your
environment. The ps(1) or other related commands can
be invoked in such a way as to display the command
line of a process. In this situation, any
authenticated user on the system can potentially see
the password while the process is executing. Hence,
it is highly recommended not to specify the password
on the command line, and instead allow the command to
prompt for the password.
-h IPaddress|hostname
This option should only be used in combination with
either the -u or -g option. IPaddress|hostname
specifies the IP address or hostname of the target
partition (-u) or complex (-g).
-g [passwd] Allows access to the complex specified by the -h
option. The accessed complex is then considered the
target complex. Access is via the service processor's
LAN port.
The -h option is required if this option is used.

passwd specifies the IPMI password of the service
processor. If this field is omitted, the command
prompts for the password.
If an error is reported when you attempt to connect
using this option, check to see that IPMI LAN access
has not been disabled on the remote service processor.
Access to the complex via IPMI over LAN can be enabled
or disabled by logging on to the service processor and
using the SA command from the Command Menu.
The -u and -g options are mutually exclusive.
SECURITY WARNING: Specifying the password directly on
the command line may pose a security risk in your
environment. The ps(1) or other related commands can
be invoked in such a way as to display the command
line of a process. In this situation, any
authenticated user on the system can potentially see
the password while the process is executing. Hence,
it is highly recommended not to specify the password
on the command line, and instead allow the command to
prompt for the password.
-c cell The specified cell is powered on/off or the power
status is displayed. Refer to the DESCRIPTION section
for the conditions under which power control is
allowed.
If a power operation on multiple cells is specified,
the command processes each one, regardless of the
outcome of the operation on a particular cell. It is
possible for an operation to succeed on one cell and
fail on another.
A cell can be specified either in the local
(cabinet#/slot#) or global (cell#) format. For
example, the cell located in cabinet 0, slot 4 is
locally identified as 0/4 or globally as simply 4.
-i I/Ochassis The specified I/Ochassis is powered on/off or the
power status is displayed. Refer to the DESCRIPTION
section for the conditions under which power control
is allowed.
If a power operation on multiple I/O chassis is
specified, the command processes each one, regardless
of the outcome of the operation on a particular I/O
chassis. It is possible for an operation to succeed
on one I/O chassis and fail on another.
Hewlett-Packard Company - 4 - HP-UX 11i Version 2: Sep 2004
frupower(1M) frupower(1M)
An I/O chassis id must be specified in the form of
cabinet#/enclosure#/chassis#. For example, the I/O
chassis located in cabinet 0, enclosure 1 and I/O
chassis slot 3 is identified as 0/1/3.
-C Displays power status of all cells. If the -u or -g
option is specified, the operation applies to all
component cells of the accessed complex.
-I Displays power status of all I/O chassis. If the -u
or -g option is specified, the operation applies to
all I/O chassis of the accessed complex.
The -c, -i, -C, and -I options are all mutually
exclusive.
-l cabinet Limits the scope of the -C or -I option to the
specified cabinet(s).
Mapping of Global Cell Numbers to Local Cell Numbers [Toc] [Back]
The cabinets in a complex are numbered starting from 0. The cell
slots in each cabinet are also numbered starting from 0. Each cabinet
can have a maximum of 8 cells. For example, the cells located in
cabinet 0 will have the following cell numbers in global format: 0, 1,
2, 3, 4, 5, 6, 7. The cell numbers in corresponding local format will
be 0/0, 0/1, 0/2, 0/3, 0/4, 0/5, 0/6, 0/7.
Similarly the cells located in cabinet 1 will have the following cell
numbers in global format: 8, 9, 10, 11, 12, 13, 14, 15. The cell
numbers in corresponding local format will be 1/0, 1/1, 1/2, 1/3, 1/4,
1/5, 1/6, 1/7.
From the above convention the cell located in cabinet 1, slot 0 is
identified in the local format as 1/0 or in the global format as 8.
The parstatus(1) command will display the above cell as "cab1,cell0".
The cell located in cabinet 1, slot 4 is identified in the local
format as 1/4 or in the global format as 12. The parstatus(1) command
will display the above cell as "cab1,cell4".
RETURN VALUE [Toc] [Back]
The frupower command exits with one of the following values:
0 Successful completion.
1 Error condition occurred.
EXAMPLES [Toc] [Back]
Power on the cell located in cabinet 0 slot 4 of a partition
identified by the hostname GreenRiver:
frupower -o -c 0/4 -u RemoteAdmin: -h GreenRiver
Hewlett-Packard Company - 5 - HP-UX 11i Version 2: Sep 2004
frupower(1M) frupower(1M)
RemoteAdmin must have root permissions on GreenRiver. Since a
password was not supplied on the command line, the command prompts for
it.
Power off two cells located in cabinet 0 slot 4 and cabinet 0 slot 6.
frupower -f -c 0/4 -c 0/6
DEPENDENCIES [Toc] [Back]
This command uses the Web-Based Enterprise Management (WBEM) product
and certain of its configuration settings. If you encounter
connection errors when using the -u option, check that the following
two conditions are satisfied:
+ Use the cimconfig(1M) command to verify (and correct if necessary)
the setting of the following two variables:
+ enableRemotePrivilegedUserAccess=true
+ enableHttpsConnection=true
+ You must have appended the target partition's digital certificate
to the local partition's Trust Store file. For the nPartition
commands, the Trust Store file is /var/opt/wbem/client.pem.
Note: You must have appended the target partition's digital
certificate to the local partition's Trust Store file. For the
npartition commands, the Trust Store file is
/var/opt/wbem/client.pem. This file is used by the commands that
come with WBEM installation. Hence, if the commands that come with
the WBEM installation trust a target partition, then npartition
commands will also trust the target partition.
Refer to the WBEM documents specified in the SEE ALSO section below
for further information.
