Array Partition Management

I have a Hewlett-Packard Proliant ML-350 with a Compaq SmartArray 532 SCSI controller and four 18.2GB hard disk drives configured as one logical RAID 5 volume (3 data disks and a hot spare) running Microsoft Small Business Server 2000. I have now updated the machine to Microsoft Windows Small Business Server 2003 Premium Edition and successfully added two 36.4GB hard disk drives to the array using the Compaq Array Configuration Program. However the operating system Disk Manager will not allow me to increase the capacity of my system volume. I can only use the new disk capacity to create a new volume. How can I solve this problem? I know this is an operating system problem as the Compaq Array Configuration Program correctly integrates the new disks into the existing array. Unfortunately Microsoft Partner Support say I can only extend a system volume by reformatting the drive and reinstalling the server or use a third party solution but they won't tell me which third party solution they mean. I have previously used PowerQuest Volume Manager 2.0 with MS Windows NT4 and 2000 Server to manage array partitions but this software has been bought by Symantec and they have informed me that it is not compatible with MS Windows Server 2003. I can't be the only person in the world with this problem. Any ideas? Best Regards Perry Reed

Thanks. We'll let you know when a new response is added.

As is known to us all Resize feature is only added into Windows 7/Vista/2008 Disk Management. The old Os cannot support extend partition with Disk Management.
There is a solution may help under such case.

    You can try partition magic to manage the volume, the reason that the array utility is not letting you add the disks to the current set is due to the size of the new disks not being that same as the old ones. looking at what you have said 4x 18.2Gb raid 5 plus the new 2x 36.4Gb drives, what I would do is remove the hot spare, put in another 36,4Gb disk and create a new raid volume, keep the hot spare disk on site to use if you have a drive failure in the 18.2Gb raid set (taking in to account that you are using hot swap drives)and move your data from the 18.2Gb raidset to the 36.4Gb raidset. note that you can not have a system partition on a dynamic disk.
