Unable to see unallocated disk space on Dell PE 2850

Hi all,

I have a Dell PE 2850 with 3 disks as Raid 5 (has OS) and a pair as raid 1. I have recently upgraded the disks to the next size up, and the have reconfigured themselves at the former size as expected. I was then expecting to be able to use Windows Disk Management to extend the partition (there's only one on each of the two sets of disks). However, disk management does not see the additional space - a right click on disk management and selecting rescan, does not change anything.

The Dell OpemManage can see the free space on each virtual disk. Selecting reconfigure from there does not allow me to extend them. - I can create a new Raid 0 on the free space.

Using the DELL extpart, it errors saying unable to retrieve the partition information. Dispart similarly fails. All disks in each array are of the same size and double the size of their presecessors (now 3 x 73 Gb in Raid 5) and 2 x 146 Gb in Raid 1. Both  Arrays are still showing around 68Gb as maximum size.

How can I extend these to use the full available space?

Whilst I have full backups, I don't really want to go to that extend. If I can extend with disk management after a backup, why can't I do that now?

Because the array controller you are probably doesn't have the capability to expand the arrays. Even if it does have the capability this doesn't always work properly.

OK Thanks. While it isn't the solution I wanted, I accept what is said.
