CentOS - Mar 2006 - SMART for SATA devices ?

I noticed that the changelog for the new kernel 2.6.9-34 on the redhat
enterprise watchlist states on of the fixes as;

145061 - SMART support in SATA driver (P1)




Does this mean that with that kernel we should be able to interrogate SATA
drives now ?

Cheers,

Bards.

It seems we will need a new smartmontools (I don't know if that's
included in
4.3) even if 2.6.9-34 now supports it:

[root at dx ~]# uname -r
2.6.9-34.ELsmp
[root at dx ~]# smartctl -a /dev/sda
smartctl version 5.33 [x86_64-redhat-linux-gnu] Copyright (C) 2002-4 Bruce 
Allen
Home page is http://smartmontools.sourceforge.net/

Device: ATA      HDS728080PLA380  Version: PF2O

SATA disks accessed via libata are not currently supported by
smartmontools. When libata is given an ATA pass-thru ioctl() then an
additional '-d libata' device type will be added to smartmontools.

[sorry to jump into this late - I'm on the digest and am behind
in my reading.  I did not see an answer in later digests yet ]

FYI, you can use the '-d ata' option to smartctl to talk to your
SATA devices with the -34 kernel.  I've been doing this with a 2.6.15.4
kernel, but back-reved to 2.6.9-34 to test this and was successful.
So if you edit your /etc/smartd.conf, you can have a line like:

/dev/sda -d ata -H -m root at localhost.localdomain

and you interactively do:

  smartctl -d ata -a /dev/sda
