new RAID drive not recognised as extra space in Windows

I have recently added another disk to a RAID 5 array.

spec: dell poweredge server
PERC 4e/di RAID controller
Windows Server 2003
DELL OMSA version 5.2 installed.

The original ARRAY consists of 3 DISKs 143GB each in size resilting in a total amount of available space of 286GB. This disk was previosly partitioned to 10GB, 20GB and 253GB drives

The last partition (253GB) is used for data. I added and extra 143GB disk to the array and wanted to increase the amount of space in the last partition of the virtual disk.

Have managed to reconfigure the array and DELL OMSA is reporting the disk correctly at 409GB however in Windows it is still showing as a 253 GB disk.

I do not really want to install 3rd party software such as partition magic.

is there something i am missing here to allow windows to see the extra space?

Thanks

As long as your not trying to expand the boot partition you can convert to dynamic disks and then expand the  parition.  If your trying to expand the boot partiton your have to use third party software.

Thanks for your reply.

Unfortunately i do not have that option in disk management.

Does anyone else have the answer??

The option is always there, your probably right clicking on the partition box on the right.  You should be right clicking the disk box on the left.

The partition is not going to expand itself so there is only 2 options.  dynamic disks or 3rd party software.  Once you converted to dynamic disks you can span the volume with the unallocated space.

Thur6165 is right. You should have that option in Disk Management. If not, you might need to go back raid bios and reconfigure.

Thankyou for your suggestions. I wanted to keep the disk as a basic disk so unfortunately this is not the answer i was looking for. I have found out that it is not possible to extend the RAID on this drive as it contains the boot partition. the only way to extend the RAID without third party software would be to restripe the array.

DELL no longer provide Array manager. It has been replaced by DELL OMSA which does not contain a tool for extending the array.
The only option I had was to create a new partition and disk using the extra drive i had added unfortunately.

Thanks again for your answers though.

I stated in the first response that you have to use third party software if your trying to expand the boot partition.
