Usage: sta [-l], stack [-l] Displays the stack trace for the current dump. Use of the -l flag causes the stack frame for each entry to be displayed. Usage: tr [file name] Displays the hypervisor internal trace table to standard out. If a file name is provided, the trace information will be saved to the specified file in a form recognized by the dsptrc command. Usage: q, quit Halts the hcrash program and returns to the unix command line. Usage: ?, help Displays command usage information. Usage: This command is currently not used with this version of hcrash. Usage: dnv [start_address] [count], dnvram [start_address] [count] Where start_address is the beginning address of nvram to be displayed and count in the length. Usage: itr, itrace Displays the instruction stream for each stack frame and the offending instruction.
