commands are communicating with BMCs using the IPMI protocol. Note that the term "IRU"
represents a single blade enclosure within a blade enclosure pair.
The cpower command is the main interface for all power management commands. You can
request power status and power-on or power-off the system with commands entered via the
administrative controller server or rack leader controller in the system rack. The cpower
commands are communicating with BMCs using the IPMI protocol. Note that the term "IRU"
represents a single blade enclosure within a rack.
The system-level commands are applied first to service nodes, then to RLCs, then to blade
enclosures and compute blades.
The cpower commands may require several seconds to several minutes to complete, depending
on how many blade enclosures are being queried for status, powered-on, or turned off.
# cpower system status
This command gives the status of all compute nodes in the system.
To power on a specific blade enclosure, enter a command similar to the following:
# cpower iru on r1i0
In this example, the system should respond by powering on the IRU (blade enclosure) 0 nodes in
rack 1. Note that this command does not power-on the system administration (server) controller,
rack leader controller (RLC) server or other service nodes.
# cpower iru off r1i0
This command powers off all the nodes in IRU (blade enclosure) 0 in rack 1. Note that this
command does not power-off the system administration node (server), rack leader controller
server or other service nodes.
See "Console Management Power (cpower) Commands" on page 8 for additional information on
power-on, power-off and power status commands. The SGI Management Center Administration
Guide for Clusters, (P/N 007-6358-00x) has more extensive information on these topics.
