L2>
r 2-4,7 <L1 command>
This is a one-time destination.
Command Interpretation
Some L2 commands are the same as the L1 commands. In many cases, this is intentional because
the L2 provides sequencing that is necessary for a command to function correctly.
When L1 and L2 commands are similar, you can ensure that an L1 command is entered for the
IRUs 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:
001c01 ERROR: invalid arguments for ‘ver’ command, try “help ver”
The general format includes an IRU 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
You can power on and power off the system with the
power
command. This command is
interpreted by the L2, because the IRUs 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.”
