My server is a PE840 and the RAID card (SAS5iR) is recognized as follows 
by dmesg:
> Fusion MPT base driver 3.04.03
> Copyright (c) 1999-2007 LSI Logic Corporation

I've compiled the "Fusion MPT ScsiHost drivers for SAS" directly into 
the kernel (an not as module):

> # Fusion MPT device support
> #
> CONFIG_FUSION=y
> # CONFIG_FUSION_SPI is not set
> # CONFIG_FUSION_FC is not set
> CONFIG_FUSION_SAS=y
> CONFIG_FUSION_MAX_SGE=128

I've installed the mpt-status deb, but when I issue the command I get:
> afaglia at cpsrv001:~$ sudo mpt-status
> open /dev/mptctl: No such device
>   Are you sure your controller is supported by mptlinux?
> Also make sure mptctl is loaded into the kernel

(the same if I issue the command as root).

/dev/mptctl exists:
> afaglia at cpsrv001:/dev$ ls -l mptctl
> crw-rw-rw- 1 root root 10, 220 2007-05-10 17:36 mptctl


Anybody could tell me:
1. why mpt-status gives me this output (although I have the char device 
mptctl) and
2. am I right with the direct compilation of CONFIG_FUSION_SAS into the 
kernel?


Thanks for your support.
Alessandro
