Operating the L2 Controller

Viewing Information, Warnings, and Error Messages
All information, warnings, and error messages generated by any of the system
controllers are in the following form:
002c01 ERROR: invalid arguments for ‘ver’ command, try “help ver”
The general format includes a brick identification and the type of message, followed by
the message. A message may be the result of an invalid command, as shown in the
example, or the result of tasks running on the L1, such as the environmental monitor.
Each L1 has a log of local events. Use the L1 command log to view events on any of the
L1s.
Powering On, Powering Off, and Resetting the System
The system can be powered on and off with the power command. This command is
interpreted by the L2, because the bricks must be powered on in a specific order.
L2> power up
L2>
The power command may require several seconds to several minutes to complete. In the
example above, all racks and slots in the default destination are affected. Any errors or
warnings are reported as described in the prior “Viewing Information, Warnings, and
Error Messages” section.
To power on or power off a specific brick, specify a current destination, as follows:
L2> r 2 s 5 power up
L2>
You can enter the power down and reset commands in a similar way, as follows:
L2> partition <partition number> <power down or reset>
Console Mode from L2
In console mode, all output from the system is visible and all input is directed to the
system.
