Powering Cells and I/O Chassis On and Off
This section covers cell and I/O chassis power management procedures,
which allow you to control power for cells and I/O chassis from remote
locations, without physically accessing the system hardware.
You can use the following procedures:
• Powering Cells and I/O Chassis On and Off [Service Processor] on
page 315
This procedure (Command menu, PE command) powers on and
powers off cells, I/O chassis, and cabinets using the service processor
interface (GSP or MP).
• Powering Cells and I/O Chassis On and Off [HP-UX] on page 316
This procedure (frupower -o -c# and frupower -f -c# commands)
powers on and powers off cells (and their associated I/O chassis)
using HP-UX.
• Powering Cells and I/O Chassis On and Off [Partition Manager] on
page 318
This procedure (Cell —> Power On Cell menu, or Cell —>
Power Off Cell menu) powers on and powers off cells (and their
associated I/O chassis) using Partition Manager.
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.
