How to get smartctl data from Dell Perc controllers ( DELL PERC controllers are not supported )
If you ever need smartd data from disks on a dell Perc controller and het this:
smartctl -a /dev/sda smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-308.20.1.el5.onappxen] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net DELL PERC controllers are not supported.
You can bypass this by polling the controller directly with:
smartctl -a /dev/sda -d sat+megaraid,0
Replace the 0 in megaraid,0 with the position of the disks in the bay. For example, the disk in bay3 would become megaraid,3
