Operating 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:
001c07 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 controller, such as the environmental
monitor.
Each L1 controller has a log of local events. Use the L1 command
log
to view events on
any of the L1 controllers.
Powering On, Powering Off, and Resetting System
You can power on and power off the system with the
power
command. This command
is interpreted by the L2 controller, because the bricks must be powered on in a specific
order.
L2> power up
L2>
Depending on the size of the system, 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 above in
“Viewing Information, Warnings, and Error Messages.”
To power on or power off a specific brick, specify a current destination:
L2> r 2 s 7 power up
L2>
To power on or power off all bricks in a partition, enter the following:
L2> partition <partition number> <power up or power down>
To reset the system, enter the following:
L2> reset
L2>
This command restarts the system by resetting all registers to their default settings and
rebooting the system controllers. Resetting a running system will cause the operating
system to reboot and all memory will be lost.
