A couple nights ago I ended up writing some userland code that expands atacontrol(8) to support display of some SMART statistics (e.g. atacontrol smart ad10)[1]. So what's this got to do with the above? ata(4) layer offers an ioctl (IOCATAREQUEST) which literally allows you to shove raw ATA commands at the disk itself. This means implementing the equivalent, i.e. atacontrol cmd, is possible. Though like with camcontrol, the implications are risky. If folks are interested, I could try working on such, though honestly the argv[] parser in atacontrol(8) needs to be re-written (IMHO). What I'm saying: folks using straight ata(4) or ataahci(4) would use atacontrol cmd while folks using ahci(4) would use camcontrol cmd. Please let me/list know if either of these things are of interest. [1]: It's hardly done and needs a *lot* of work, but I'll eventually get it into a state where it could be committed and people could hack on it/improve it. It's no where near as defined as smartmontools (re: disk vendor/model one-offs for attribute parsing and so on), but I figured FreeBSD users might want something out-of-the-box which might give them stats which are most commonly focused on (sector reallocation, drive temperature, high spin-up times, CRC errors, etc.). I guess you could say I'm a bit proud of myself given that I was able to figure out how to accomplish it by looking at some smartmontools source (messy, let me tell you...) and ata(4) bits (since the ioctls aren't documented). [2]: Yes, I'm still working on writing that doc that explains how to read SMART data. Going to have to end up doing it for work as well... oh the joys. :-) -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Trouble with drive size detection - 31MB visible size on 1TB drive.
Hi all! I have a problem with drive size detection. After any power cycle my HDD ST31000340NS detected by FreeBSD 7.2 as 31Mb drive. For example: Dec 9 20:33:12 green kernel: ad14: 31MB Seagate ST31000340NS SN06 at ata7-master SATA300 Dec 9 20:33:12 green kernel: GEOM: ad14: corrupt or invalid GPT detected.

Why drive locks HPA? And... Can I unlock HPA from FreeBSD? HPA means Host Protected Area. It is a method for BIOS or some other infrastructure to reserve some space on disk for own use. May be previously this drive was inserted into some RAID, which protects data on disk in that way. I have doubt that unconditional HPA unlock during boot that seems Linux does is a proper behavior for the OS. IMHO it breaks general idea of HPA. To unlock drive permanently SET MAX ADDRESS ATA command should be used (probably the same as Linux uses) with Volatile bit set, to make it not restore on power cycle. I don't know how to send this command with legacy ata(4), you need some external tool. With new CAM-based ATA probably it can be send via `camcontrol cmd ...`. -- Alexander Motin ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
