Hi, I have xserve with Lacie s2s, how to connect them

in initial state to Xserve(fan heigh sound), the Lacie lamb don't work but when I run Xserve in standalone state(slow fan), the lamps work. I forget how to install the lacie,

I log to Xserve system, setup the drivers for pci-x card and lacie driver and lacie manager, but the server don't show any thing that connected,

the lacie manager don't show any hard, as well as the Disk Utility.

I can't see any hard in work group manager when i enter locally or by remote so I don't have any share point.

Please help me to connect the lacie again to the Xserve, thnx
