Command Interpretation
Some L2 commands are the same as the L1 commands. In many cases, this is intentional
because the L2 emulator provides sequencing that is necessary for a command to
function correctly.
When L1 and L2 commands are similar, you can assure that an L1 command is entered
for the bricks in the current destination by preceding the command <
L1 command
> with
the
l1
command:
L2> r 2-4,7 l1 <L1 command>
This is a one-time destination.
Viewing Information, Warnings, and Error Messages
All information, warnings, and error messages generated by any of the system
controllers are in the following form:
001c05 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 From the L2 Emulator
You can power on and power off the system with the
power
command. This command
is interpreted by the L2 emulator, 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 above in “Viewing Information, Warnings, and Error
Messages.”
