Powering Cells And I/O Chassis On And Off - HP Rp7410 - Server - 0 MB RAM Administrator's Manual

2. Check the VFP status to see whether any cabinet hardware is running an operating system
(OS).
Any nPartition whose state is "OS heartbeat" is running an OS and thus should not have its
hardware powered off until after the OS is shut down.
Type ^b (Control-b) to exit the VFP.
3. Shut down the OS running on any cabinet hardware that you plan to power off.
4. Confirm that nobody else is using or servicing the cabinet hardware you plan to power on
or off.
Both physically inspect the hardware and check whether others are remotely accessing the
service processor (using the WHO command at the Command menu).
5. Access the service processor Command menu, issue the PE command, then select the cabinet
to power on or power off.
From the service processor Main menu, enter CM to access the Command menu. To exit the
Command menu enter MA.
When using the PE command enter B to power on or off a cabinet; specify the cabinet number;
and then enter ON (power on), OFF (power off), or Q (quit without changing the power status).
GSP:CM> PE
This command controls power enable to a hardware device.
B - Cabinet
C - Cell
I - IO Chassis
Enter cabinet number: 1
The power state is ON for Cabinet 1.
In what state do you want the power? (ON/OFF)

Powering Cells and I/O Chassis On and Off

You can power on or power off cells and I/O chassis by using any one of the following procedures:
• "Powering Cells and I/O Chassis On and Off (Service Processor)" (page 207)
• "Powering Cells and I/O Chassis On and Off (nPartition Commands)" (page 208)
• "Powering Cells and I/O Chassis On and Off (Partition Manager)" (page 208)
You can control power for cells and I/O chassis from remote locations, without physically accessing
the system hardware.
NOTE: On HP nPartition systems, powering on a cell also powers on any I/O chassis attached
to the cell, and powering off a cell also powers off any I/O chassis attached to the cell.
Powering on or off an I/O chassis connected to a powered-on cell causes the cell to reset if the
cell located and mapped the I/O chassis during its cell boot process.
The frupower command and Partition Manager permit you to power on or off inactive cells
and I/O chassis that are assigned to the current nPartition or are not assigned to any nPartition.
The PE command at the service processor Command menu permits you to power on or off any
hardware in the complex, including active cells and I/O chassis. The PE command does not check
the current usage of components.
