Managing Superdome Complexes: A Guide for HP-UX System Administrators

Managing the Overall Complex

Detecting / Controlling Power in the Complex

Chapter 394

Step 1. Log in to the Superdome complex’s GSP and access the GSP command

menu.

From the GSP main menu, enter CM to access the command menu.

Step 2. Issue the PE command and specify the type of hardware whose power you

want to turn on or turn off.

You can manage power to cells, I/O chassis, and cabinets (including all

components in the cabinet).

Step 3. Specify the hardware device to power on or power off.

For cells, specify both the cabinet and cell slot in which the cell resides.

For I/O chassis, specify the cabinet, bay, and chassis where it resides.

Note the following issues when using the GSP command menu to

manage Superdome hardware power.

• When you power off an I/O chassis from the GSP command menu, the

system ﬁrmware resets the cell attached to the I/O chassis.

• When you power off a cell, the ﬁrmware also powers off any I/O

chassis attached to the cell.

• When you power off a cabinet, the ﬁrmware also powers off all cells

and I/O chassis in the cabinet.

The GSP does not check whether the speciﬁed component is being used;

this means you can power cycle hardware that a partition is actively

using.

In the following example the GSP powers off cell 2 in cabinet 0.

GSP:CM> PE

This command controls power enable to a hardware device.

B - Cabinet

C - Cell

I - IO Chassis

Select Device: c

Enter cabinet number: 0

Enter slot number: 2

The power is ON for the Cell in Cabinet 0, Slot 2.

In what state do you want the power for the

Cell in Cabinet 0, Slot 2? (ON/OFF) OFF
