Raid Capability Detection

If these are all sysfs based distros you can use that.

`cat /sys/class/scsi_host/host?/proc_name`

This will list the devices and their drivers. The drivers aacraid,
megaraid, and megaraid_sas are RAID drivers. Everything else is just
plain SCSI/SAS.

Subject: Raid Capability Detection

Hello Everybody,

I am working right now on a architecture based on differents Poweredge 
Systems. The problem is that I have servers with Ultra SCSI Card without

RAID Capability and others with Perc Controlers with RAID capability.

I would want to know if there is a generic way to detect the model card 
and if it is possible to know if the controler is RAID capable or not. I

would like to avoid to parse the lspci output because I have to do this 
detection on several distrbutions on where the lspci output is

Does somebody have any idea to do that ?

Thank you for your answers
