No problem, and thank you again.

Now i'm sure that is a must have.
Since 4 years to last year, we just had Hardware RAID, so we didn't need to do any actions on HDD...
Now with md RAID we need ! :)

Ok, really bad...
But i have another problem, hpacucli don't work with all kernel version !
To avoid details, i show you my results :
2.6.32.5-amd64 : OK
2.6.38-bpo.2-amd64 : NOK
2.6.39_bpo.2-amd64 : NOK
3.2.0.0.bpo.1-amd64 : NOK
With the two kernels 2.6.*bpo* it work well to show config, show everything you want.
To delete, it's Ok too.
But to Create it never give me my shell back ! Better, after the create try, it freeze all disk command like pvdisplay, or mdadm --detail /dev/md0
All this command was just blocked ! I show you what i read in kern.log :
[ 960.508752] INFO: task arrayprobe:9011 blocked for more than 120 seconds.

With kernel 3.2* it don't find any controlers :
# hpacucli ctrl all show config
Error: No controllers detected.
I'm looking for a solution and i have seen that the version 8.70-8.0 is not the last one.
But i don't find any 64 bit deb file to use... rpm, yes ; i386, yes...
Of course nothing in your
link :(
Still searching...

You're welcome Julien. Sorry I didn't mention it sooner. It took me a
little while to figure out exactly what your problem was, due to

I'm kinda surprised you didn't already know about this tool. It's a
must have. Without it, how can you manage the RAID controller and disks
once the system is in production?

There was a very long discussion about this some time ago. The
consensus seems to be that if you must install a 32bit library, there is
no downside, unless it replaces an existing library that other programs
use, and breaks those programs in the process. I do find it odd that an
amd64 package has a 32bit library dependency. Then again, stuff like
this isn't all that rare when installing commercial software.

Clear and simple is exactly what you want/need in a cli administration
utility.
FYI, the Areca PCIe RAID cards have a 10/100 ethernet port and you
manage them via a built in web interface, out of band. No software to
install, as the kernel driver is in mainline (in recent kernels anyway).
I'm not plugging Areca here, as the cards are apparently lacking
somewhat in the performance department WRT competing cards in the same
price range, and customer support is seriously lacking. Just pointing
out how handy an OOB web management interface can be.
