freebsd stable - Mar 2006 - Need help with isp driver and disk arrary

I am having a problem with the isp driver seeing a StorageTek disk
array LUNs.  I am directly attaching to the array and everything works
find as long as I plug into the A controller on the array.  When I
connect up to the B controller, I can not see any of the LUNs
advertised.  The QLogic firmware can see the LUNs. The only difference
I can see are that the LUNs start at 0 on the A side and at 3 on the B
side.

Kernel messages for the isp driver are:

isp0: <Qlogic ISP 2312 PCI FC-AL Adapter> port 0xa000-0xa0ff mem
0xec060000-0xec060fff irq 17 at device 0.0 on pci1

camcontrol devlist -v shows the following when connected to port A:

scbus0 on isp0 bus 0:
<STK BladeCtlr B210 0612>          at scbus0 target 0 lun 0 (da0,pass0)

scbus-1 on xpt0 bus 0:
<  >                               at scbus-1 target -1 lun -1 (xpt0)

camcontrol devlist -v shows the following when connected to port B:

scbus0 on isp0 bus 0:
<  >                               at scbus0 target -1 lun -1 ()
scbus-1 on xpt0 bus 0:

In 5.x (and probably still applies to 6.x) LUN's have to start at 0 in
order to be visible. So you have to change or LUN-mask so they start
at 0.
