Increase size of RAID-5 array/logical drives

I have a DL380G3 with a 3-disk RAID-5 (3x 36.4GB). The controller is an embedded Smart Array 5i. The array is configured with one logical drive - a basic disk in Windows that has two partitions: a 20GB system partition (C: drive) and a data (D:) drive. Both partitions are pretty much tapped on space, so I need to increase the size of both.

What is the best way to go about doing this? Can I just add a few more 36.4GB disks, expand the array with ACU and then use diskpart in windows? I am somewhat lost. Is there an HP document I can refer to?

Thank you.

Yes, you can add disks to that RAID and then increase the size of the logical drive. This will leave you with a 20 GB partition, a 50 GB partition and some free space.
To modify partitions you can use diskpart utility, but modifying C: would not be possible I think, as it has D: partition in front of it.

Thank you both.

Once I have the array expanded and the logical drive extended, are there any 3rd party tools out there you would recommend for increasing the size of the c: drive?

Thank you.
