No /dev/cciss

[Chris du Preez]

I have upgraded my workstation to Ubuntu 9.10 server with 2.6.31-20-server 
kernel. I have a HP Smart Array 642 card in my machine. The kernel doesn't 
pick up the card anymore, there is no /dev/cciss directory with the device 
files for my hard drives connected to this card. I would appreciate it if 
someone can tell me what to do or where to read in order to rectify this 
problem.

Thanks in advance
