SMART disk monitoring

I've just downloaded smartctl from Blastwave and it works against my SATA disks;

# /opt/csw/sbin/smartctl -d scsi -a /dev/rdsk/c9t2d0s0
smartctl version 5.38 [i386-pc-solaris2.8] Copyright (C) 2002-8 Bruce Allen
Home page is http://smartmontools.sourceforge.net/

Serial number: 9QM4SAL7
Device type: disk
Local Time is: Mon Jun 8 10:32:07 2009 BST
Device supports SMART and is Enabled
Temperature Warning Disabled or Not Supported
SMART Health Status: OK

Current Drive Temperature: 45 C

Error Counter logging not supported
No self-tests have been logged


Doesn't seem to work for the IDE root yet but after a spate of SATA disk failures I'm not too concerned about that.
