DBAN has drivers for most RAID implementations, but DBAN does not automatically disassemble RAID volumes. (If you want this feature, then use EBAN instead.)
The operator must manually disassemble RAID volumes and put each component into "JBOD" or "SINGLE" mode for the disks to be recognized by DBAN. For Adaptec AIC-7902 and IBM ServeRAID host controllers, the operator can do this by running the SCSI BIOS Setup Program and disabling the "HostRaid" toggle.
This procedure varies between RAID implementations.
