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 perform these procedures using the following methods:
• Service Processor (GSP or MP) on page 259
This procedure (Command menu, PE command) powers on and
powers off cells, I/O chassis, and cabinets using the service processor
interface.
• HP-UX Commands on page 260
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.
• Partition Manager on page 261
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
partition or are not assigned to any partition.
The service processor Command menu’s PE command permits you to
power on or off any hardware in the complex, including active cells and
