The issue you are seeing is that the raid controller, when given a larger drive as the original, will rebuild the replacement drive the same size as the drive sizes in the original configuration. Hence the 250GB.
Now to confirm, from your description it sounds like you currently have 2 1TB drives, as well as 2 500GB drives within the Raid 5 currently, is that correct?
The suggested route to take would be to backup the data, delete and reconfigure the array as 500GB for the drive sizes, that is due to the fact the 500GB are the smallest drive in array. The reinstall and restore data from backup.
Another option is rebuild the 500GB/1TB drives with 2 additional 500?MB1TB drives, giving you 4 1TB drives. Once all the drives match you will see the additional space, which you can then configure into another virtual disk and expand in the partitions. Now be advised, that in the case that you have a drive failure, there can sometimes be issues.
If you create a second array across the disks using the newly available space, you can't "expand the partitions" using that space. You could convert the disks to Dynamic and span them, but that is NOT recommended. EITHER configure a second array with the new space (this will be presented to Windows as a separate "disk") ... OR backup the data, configure larger RAID 5, restore data, expand partitions.
RAID expansion by replacing disks with larger ones is not supported on the PERC 6 and is only available starting with the PERC 7 (H700), with updated firmware, and for specific setups.
