Rookie unable to get HP storageworks MSA60 to be seen

Hi,

I've installed ESXi 5 on a HP DL380 G5 that has a Storageworks MSA60 with 9 300gb sas drives directly connected to it via a smart array P800 controller. Using Vsphere 5.1 I can see the P800 controller but nothing connected to it though I can see the internal drive on the DL380 connected through another controller. I'm not sure if its the Storageworks thats not compatable or someting else.

Any help greatly appreaciated as i'm on a steep learning curve.

Regards
