The volume you have selected may not be extended

Hello, I have an HP proliant server with 4 72gb drives. I have a C partition that is 12gb and a D: (data) partition that is about 192gb. I've just added 2 additional 72gb drives. I've gone in and expanded the array to include these two new drives. Now I have 1 array that has 6 drives instead of 4. At this point I thought I was ready to run diskpart so I can extend my D partition into the extra space. However, for whatever reason, I keep getting the error that tells me that the partition may not be extended. The extra space does show up in disk management. Initially it showed up as unallocated space. I right clicked on it and created a new primary partition and assigned all 132gb to the partition. I did not assign a drive letter to the partition however. I also did not format the partition. I am also running Windows server 2003 R2 with SP2 and all the critical updates. I did find a microsoft KB article that talks about a hotfix for this problem but they don't have a download for x486 English. http://support.microsoft.com/kb/841650. I've also tried formatting the new partition but that didn't make any difference. Please help!! I do not know what else to try. Thank you.

Hello, yes the array expanded just fine. When I go in to Disk Management, both the C and D partitions show up as primary partitions. I want to extend the D partition which only has data but for some reason someone made it a primary partition. I believe the page file is on C

Being a primart partition is quite normal. Are you sure there is no pagefile on D:?

Are they partitions on a single disk or is the array setup with 2 logivcal disks in the ACU?

Correct. There is no page file on D:\. The partitions C and D are on one logical disk. The logical disk size is now over 300gb and my c and d partition only occupy 200 but for whatever reason I cant get the D: partition to extend. Could it be how I have the extra space prepared? Should the extra space be formatted? Should it be assigned a drive letter? How should it look in disk manager?

There shouldn't be a partition or drive letter on the extra space but as far as I read there wasn't one when you first tried to extend, only after it failed and you poked around a bit.

The HP document told me to create a new volume using the new space. When I just left the new space as "unallocated space", the partition extended fine. Thank you.
