"Create Array" is not visible on Array configuration utility

Hi,

I was trying to expand my HP ProLiant server by adding additional hard disk. I was having 300 GB x 3 + 600 GB x3 hdd in different Raid 5. Now i wanted to remove the 600 GB x 3 and add 1.2 TB x 5 hdd and make the same Raid as before, so i will have 4.8 TB as storage. I did remove the 600 GB x 3 and added 1.2 TB x 5, but when i run HP Array configuration utility i cant find there create array to create new array. Can somebody help me on this.

Thanks and regards,
