Hi!

Recently I have deployed some HP server with SSD's behind a SmartArray P410 controller. While not official supported from HP the server work well sofar.

Now I like to get wear level info's, error statistics etc from the drive. While the SA P410 supports a passthru of the SMART Command to a single drive in the array the output I was not able to the the interesting things from the drive.

In this case especially the value the Wear level indicator is from interest for me (Attr.ID 233), but this is ony present if the drive is directly attached to a SATA Controller.

smartctl on directly connected ssd:

# smartctl -A /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/

smartctl on P410 connected ssd:

# ./smartctl -A -d cciss,0 /dev/cciss/c1d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net

(Right, it is complety empty)

smartctl on P410 connected hdd:

# ./smartctl -A -d cciss,0 /dev/cciss/c0d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net

Current Drive Temperature: 27 C Drive Trip Temperature: 68 C Vendor (Seagate) cache information Blocks sent to initiator = 1871654030 Blocks received from initiator = 1360012929 Blocks read from cache and sent to initiator = 2178203797 Number of read and write commands whose size <= segment size = 46052239 Number of read and write commands whose size > segment size = 0 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3363.25 number of minutes until next internal SMART test = 12

Do I hunt here a bug, or is this a limitation of the p410 SMART cmd Passthru?
