Somewhere in the dim and distant past I was told (or read) to use:
"sync; sync; sync; halt"
Presumably so you had thinking time before automatically restarting a possibly sick system.
- jmj42 13y agoThis is likely a sun thing. Halt on (SPARC) Solaris does not shutdown the OS. It issues a reset command to the firmware. The halt command on Solaris is roughly equivalent to pressing the reset button on a PC. When your Sun is particularly hosed we used sync;sync;sync; halt to reset and (hopefully) not lose any data (sync forces OS write buffers to purge)
