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?
