Drive cylinders not correct

I installed Solaris 10 on a brand new box (HP proliant dl380g5), the box has two raid controllers (p400) with 4 72gb disks each configured in a RAID5 array. They should have 210GB usable each. Solaris will however only let me address approx 30gb (boot controller) on one and 50gb on the other. This isn't making any sense to me, can someone shed some light on this subject for me?
