IF your using the embedded SATA RAID controller it does not appear that a driver disk has been released for SLES11. You need the aarachi driver which does not ship with any distribution as it is a closed source driver. The RAID function of the embedded controller is software based and needs the driver.

I didn't install any driver on SLES11 and it seems work.

If i detach an HDD, system start and work normally.

At the reboot the BIOS alert me that di ARRAY is DEGRADED, thus i rebuilt it.
