Hello everybody,
Frank, we have decided to use soft RAID to optimise our supervision and to
optimise our RAID with all the tool that linux provide !
And for me it's better to optimise a RAID5 (RAID6) than use a non optimised

Hi Stan,
First, i tell you a huge thanks !
The ACU software is just what i need to better administrate hardware.
Just one problem, the dependecies will "dirty" my server :
# aptitude install lib32gcc1
Les NOUVEAUX paquets suivants vont être installés :
lib32gcc1 libc6-i386{a}
# dpkg -i lib32st

Like I Said in the first thread :
My Hardware is HP ProLiant DL380 G7, with HP Smart Array P410i Controller
version 3.50.
This is a Smart Array, and it present to the server the disk (RAID0)
directly.
So with 8 SAS HDD (8 RAID0) I have made a RAID6. Performances are amazing
comparate to hard RAID

Thank you for your answer Stan,
Yes, I'm not a specialist about this kernel data structure, but i'm on the
way ;)
It's not so easy to find clear information about that.
So for you, if i upgrade my kernel it will be possible to use this

Hi,
I'm trying to understand why this directory is empty : /sys/class/scsi_host/
We have two types of servers, one like that
# uname -r ; cat /etc/debian_version
2.6.32-5-amd64
6.0.4
And other one like that
# uname -r ; cat /etc/debian_version
2.6.39-bpo.2-amd64
6.0.4
On the first one :

Oh, not you, Julien. I was addressing Frank who is running Lenny's

I already have seen this blog, and the folder /sys/class/scsi_host/ is not

Humm... Nice ! For now i can't install this tools because of too many
unwanted dependencies,
but after installed it on a test server, it seems to give great results.
Thank you for all your answer.

Apparently it's as easy as this:

Where 0 is the the controller number. This information

First, we use Soft Raid because we like mdadm so much ! ;)
We have amazing performances and a nice supervision on all the RAID status.
We will keep Software RAID.
The only weak point is that HotPlug.
To Frank, I have tried that :

And I have a write erro

Hello Frank,
Fist of all, thank you for your fast answer.
I use Soft Raid... and not Hard. So the disk array present me all the disks
without any RAID or control.
So if i want to remove a HDD, i have to set it faulty and logical remove

And when i wan
If you use the onboard controller there is no need to do some software voodoo.
Just replace a faulty drive by a new one. The rebuild starts automatically.
Your device is /dev/cciss/c0d0
