IRIS 3030 - Appendix B: System Messages; Device Abbreviations

Appendix B: System Messages
When the Un i x kernel on an IRIS workstation reaches an unrecoverable error
condition, it displays an error message preceded by the word panic:.
If the error message includes one of the abbreviations listed in Table B-1, the
condition is probably caused by a hardware problem. Table B-1 lists the
devices associated with each abbreviation. The abbreviated device names are
usually followed by a digit indicating a physical unit or letters referencing the
function that lead to the problem.

Table B-1: Device Abbreviations
If the panic message does not indicate one of the devices listed in Table B-1,
there may be a hardware problem with another part of the system (processor
board, memory board, or backplane, for example) or a software problem in the
kernel.
Anytime you get a panic message, try to run sync and reboot (see Section 3.1 or
3.2). Run fsck to check the file system. If the message reappears, call the
Geometry Hotline (see Chapter 1).
NOTE: Do not interrupt (e.g., by pressing
Ctrl-c
)
processes that are accessing the no-rewind tape device.
Attempts to do this always result in a kernel panic.
