If you have rebuilt both drives into the array, where the virtual disk is listed, there should be a reconfigure option that should bring up a wizard to allow you to add the additional space. Just be sure to check the RAID level when it comes up so you make sure you have the one you want.

Actually, this isn't possible. You can only reconfigure by adding physical drives.

Copied and pasted from my post here.

If you were to replace 1 drive at a time and let it rebuild the extra space is not available to extend any partitions. At most you'll be able to make a 2nd virtual disk, but it would need it's own partition. This is a limitation of the PERC adapter (and most raid adapters our there for that matter (I've looked into raid controllers that don't have this limitation and I couldn't find any among the major (but affordable) brands).

Your best bet is the following:
- buy an imaging-based backup application (if you don't already have one like Norton Ghost or so)
- back up all your data
- update all drivers and firmware for the whole server; bios, perc drivers, perc firmware, nic drivers, etc.
- run an image-based backup (easier to a restore)
- shut down the server
- pull the 2 existing drives and mark which came from which slot
- put in the 2 new drives
- use the PERC bios to make a new raid 1
- let this initialize
- restore your backup image and let it resize the partitions at the same time (most modern imaging-based backup applications allow for this)
- reboot your server and you should be in your OS.

If its not possible, how have I done it before...

You were adding drives to a raid 5 or reconfiguring from a raid 1 to a raid 5.

On the PERCs swapping the drives in a raidset (one at a time) with larger ones will not allow you to use the extra space to grow an existing virtual disk.

If you mean adding drives to a RAID 5 by adding larger ones, letting them rebuild one at a time and then reconfiguring to include the free space of the larger drives in the same RAID array and level, then yes, I was adding drives.

It seems that this is not related to "expand" but "clone" or transfer. You may try partition master, it can copy a raid to anther RAID array, also resize the partition size to fit for the target partition.

To expand RAID partition, you may try to use Partition Assistant, I ever  use it to complete the operations on my server 2000.

Partitioning tools will not accomplish what is being discussed here.  RAID "partitions" are different from Windows partitions ... partitioning tools will only work on Windows partitions.

When you say you did the Reconfigure on larger drives, did you do it from Windows or from CTRL-R (BIOS)?
