3.2.4 crash
The crash command forces a crash dump to the selected device for DIGITAL UNIX
and OpenVMS systems. Use this command when an error has caused the system to
hang and can be halted by the Halt button or the RMC halt command. The crash
command restarts the operating system and forces a crash dump to the selected
device.
Refer to OpenVMS Alpha System Dump Analyzer Utility Manual for information on
how to interpret OpenVMS crash dump files.
Refer to the Guide to Kernel Debugging for information on using the DIGITAL
UNIX Krash Utility.
