The crash command forces a crash dump at the operating system level (DIGITAL
UNIX or OpenVMS). This command is used when an error has caused the system to
hang and can be halted with the Halt button or the RCM 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.
