This value is | used by the drive to determine how long to wait (with no disk | activity) before turning off the spindle motor to save power. | Under such circumstances, the drive may take as long as 30 sec- | onds to respond to a subsequent disk access, though most drives | are much quicker. The encoding of the timeout value is somewhat | peculiar. A value of zero means "off". Values from 1 to 240 | specify multiples of 5 seconds, for timeouts from 5 seconds to | 20 minutes. Values from 241 to 251 specify from 1 to 11 units | of 30 minutes, for timeouts from 30 minutes to 5.5 hours. A | value of 252 signifies a timeout of 21 minutes, 253 sets a ven- | dor-defined timeout, and 255 is interpreted as 21 minutes plus | 15 seconds. | | I googled but I did not found anything like this for FreeBSD :/ Well this almost certainly doesn't help your question at all, but when I upgraded a box from 4.x to 5.2.1 recently I found it was spinning down one of the disks without twiddling with any settings at all. This, in turn, appears to have caused the box to lockup/panic (can't remember now) so I had to make a cron job that wrote to the disk every minute to stop it from spinning down! I would love to know if there's some tool which can be used to just turn this behaviour off completely! | | Arne | -- | compiling millions of tiny c-programs...done | checking for a working configure script... not found | _______________________________________________ | freebsd-hackers@freebsd.org mailing list | http://lists.freebsd.org/mailman/listinfo/freebsd-hackers | To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
