check the volume created on that array, check the volume mapping on your controller. there's a possibility that there are two volumes created or one volume but mapped on two hba's. does this two scsi device have the same size? the best way is check the mapping of the scsi device on the initiator(linux). you can use sg utilites. check which ID, LUN that this device mapped to. you can also check the system logs or post the /var/log/messages so that we can help you. hardware raid is more transparent to the OS.

Software RAID is implemented by the OS, so it's not transparent. You will still see all your hard drives (in dmesg, or by using fdisk and company), but you should notice that you're now mounting the software RAID devices, /dev/md*.
