Depending on the type of system crash dump, icrash can create a unique report that contains information about what happened when the system crashed. The icrash command can be run on both live systems or with any namelist file and core file specified on the command line. The namelist file must contain symbol table information needed for symbolic access to the system memory image being examined.
Each version of icrash is specific to the OS release that it came from, and will not work on any other OS release. Do not copy icrash to any other IRIX system unless the OS versions are identical (including patch levels). Running icrash on a live system can sometimes generate random results, as the information being viewed is volatile at the time it is displayed.
