I read some code samples from the Internet and most seems to be doing the same thing. Thanks in advance _______________________________________________ Do not post admin requests to the list.

One thing to watch out for is that shutting machines down can mess up the battery hardware on the newer Xserve RAID cards. (Yes, you read that right.) This happens if the battery system is in its "conditioning" phase (which happens every few months, automatically), and there is **no warning** about this for users operating from non-GUI sessions. I filed a bug report about this, which was closed for no particularly obvious or good reason. The only way to test for this is to run the raidutil tool and check the output to see if the battery is conditioning. (This stupidity is *particularly* clever, I've found in conjunction with software updates, since the latter often requires a reboot, but if your RAID battery is conditioning at the time, it can become quite upset and insist on running with the cache turned off. The only general solution is to replace the RAID battery, which on the newer Xserves is quite an exercise... It is also especially intelligent behaviour if you're attached to a UPS and the power fails, since it's clearly more important to "condition" the battery at that point than it is to shut the server down gracefully. But I digress...) Kind regards, Alastair. -- http://alastairs-place.net _______________________________________________ Do not post admin requests to the list. They will be ignored.

I think I recognise text which has survived in manpages from the dawn of unix. The analogous manpage on SunOS (which appears not to have survived into this BSD) documented a 'rapid shutdown' option which could be used "for example, if the processor is on fire". I always thought this presumed a rather stylish coolness on the part of the admin issuing the command.

It also states that launchd is signalled appropriately. I wouldn't consider 'shutdown -r now' to be violent, just rapid. _______________________________________________ Do not post admin requests to the list. They will be ignored.
