Example 11-20. Crash Command

The crash command forces a crash dump at the operating system level. This
command is used when an error has caused the system to hang and can be
halted with the Halt button or the RMC halt command. This command
restarts the operating system and forces a crash dump to the selected device.
The syntax is:
crash [device]
device is the name of the device to which the crash dump is written.
