I stumbled upon some strange behavior when conducting some SCSI target testing in my lab that caused me to do a double-take. If a FreeBSD system detects a drive with Adaptec RAID controller meta data on it, the ataraid() driver will attempt to interpret that data as a real volume. It makes no difference to the ataraid() driver if there is an Adaptec controller physically present in the system or not. I.e. if you insert a drive that was part of a volume from an Adaptec RAID controller into another system, the new system will attempt to treat that disk as though it were associated with a HOST Raid controller. I don't think that this is the desired behavior. Even if the host raid meta-data is detected, the system shouldn't attempt to treat the disk as part of a HOST raid set without the appropriate controller in the system. -- Sean Bruno MiraLink Corporation 6015 NE 80th Ave, Ste 100 Portland, OR 97218 Phone 503-621-5143 Fax 503-621-5199 MSN: sbruno@miralink.com Google: seanwbruno@gmail.com Yahoo: sean_bruno@yahoo.com
