megaraid_sas waiting for command and then offline

["David N. Welton" <d.welton@webster.it>]

Hi,

I found someone corresponding to your name writing about a problem with
the megaraid sas driver/hardware on the LKML:

http://lkml.org/lkml/2006/9/6/12

We have a Dell (2950, running 2.6.18 #1 SMP) as well, and the way I
managed to kill the thing dead in its tracks (symptoms basically what
you you describe) is with smartctl:

root@salgari:~# smartctl --all /dev/sda
smartctl version 5.34 [i686-pc-linux-gnu] Copyright (C) 2002-5 Bruce Allen
Home page is http://smartmontools.sourceforge.net/

Device: DELL     PERC 5/i         Version: 1.00
Device type: disk
Local Time is: Wed Oct 25 10:14:40 2006 CEST
Device does not support SMART

Error Counter logging not supported


Device does not support Self Test logging

Dead in the water.  We suspect that in any case there are some disk
problems, which is why we were trying to use smartctl in the first place.

I was just curious if you managed to figure anything out...

Thanks,
