I deseperatly tried to install this OS (Centos6 : 6.1 or 6.2) on our C6100 chassis (2 nodes version with 6 * SAS HD by nodes )

But unfortunaly, after the installation done, the server become unstable once we start to stress the disk (SAS)

we see a ton of this message below in log file (messages)

then after a moment, a new HDD appear

I tried with the standard mpt2sas kernel module (8.0) and also with the last available on the lsi site (12.00),
without resolve this issue

Have you an idea about this problem ?

FYI: i just discover this chassis and i don't known the architecture of this hardware (it seem more complex than only 2 lames on a blade server no ?)

Thanks for your answer and your information (documentation, setting, etc...)
