Thanks Andre'
Looks like I have become really rusty in HW now anyway I was pressing F8 when it was at the ILO and it was taking me to ILO settings and then I waited and then saw another F8 command appear and found that it takes me to the disk drive configuration as you had mentioned.
Yeah I set it to RAID 5 and I got around 203GB. At least now I can create 4 VMs on it and put some GUEST OS to practice. Very helpful. As, I said I have become really rusty..... without touching HW for almost several years.
