Hi,
does any of you know a possibility to power down external SATA drives when shutting down FreeBSD with shutdown -p?
My situation is as follows:
- FreeBSD 8.0-STABLE, GENERIC kernel
- 3x Seagate 1TB HD at an Silicon Image 4-Port SATA-Controller
- "shutdown -p now" powers down system, but leaves eSATA drives powered up and spinning
I can use atacontrol or ataidle do spin down disks or set spin-down timers, but the final SYNC the kernel issues before powering off wakes them up again.
Here

and here
http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg67333.html
the same problem is discussed for another use case. They suggest altering the ad_shutdown function in the kernel's ata-driver, which helps for shutdown -h or shutdown -r, but not shutdown -p :-(
Any ideas?
Thomas
