DESCRIPTION

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 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.

Refer to the HP System Partitions Guide for a description of the partition management terms used in this man page.

Options and Arguments

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 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.

Note: Specifying passwd on the command line will not be supported in future releases.

-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.

Note: Specifying passwd on the command line will not be supported in future releases.

-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.

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

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 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 command will display the above cell as "cab1,cell4". See parstatus(1).

RETURN VALUE

The frupower command exits with one of the following values:

0: Successful completion.
1: Error condition occurred.

EXAMPLES

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 

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 

WARNINGS

HP-UX 11i Version 2 is the last HP-UX release on which passing passwd for the -u and -g options is supported. Specifying passwd on the command line will not be supported in future releases. The command will prompt for the password.

DEPENDENCIES

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 command (see cimconfig(1M) in the WBEM product documentation) 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.
