I also have two 3w_9xxx since a few weeks, works great! If it becomes /dev/sdb, have a look into /sys/block/sdb and /proc/partitions if it appears correctly. Also, certain devices may be excluded from scanning via /etc/lvm/lvm.conf. Does hotplug create /dev/sdb dynamically and in time during boot? In the beginning I got problems, as the 3ware controller and my SATA backplane both may be configured to delay the disk spinup. This caused some timeout trouble.
