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.
