Powering Cells and I/O Chassis On and Off
You can power on or power off cells and I/O chassis within a Superdome
complex by using system software.
The procedures in this section allow you to control power for Superdome
cells and I/O chassis from remote locations, without physically accessing
the Superdome server hardware.
NOTE On Superdome servers, powering on a cell also powers on any I/O chassis
attached to the cell. Likewise, powering off a cell will power off any I/O
chassis attached to the cell.
For details on checking Superdome hardware power status, see
“Determining Hardware Power Status” on page 84.
GSP Use this procedure to power on or power off cells, I/O chassis, and
cabinets through the Superdome complex’s GSP.
From the GSP command menu, you can manage the power for all
components within the Superdome complex, regardless of the
components’ partition assignments (if any).
CAUTION Be certain to correctly specify the cell, I/O chassis, or cabinet when using
the GSP command menu’s PE command to power on or off hardware.
The PE command does not check whether the hardware is actively being
used.
You can perform this task using GSP menus,
HP-UX commands, or Partition Manager.
