Add Physical Disks to RAID 1 Virtual Disk on H730P?

Is it possible to add 2 more physical disks to a RAID 1 array (new disks identical to the old disks) on an H730P without destroying the original mirror? OMSA isn't showing an option to keep the original RAID type when I do a Reconfigure in the software, but is it maybe possible in the controller BIOS? And without destroying and rebuilding? I would reboot and check myself, but it's a heavy production server and I don't want to ask for a maintenance window to reboot it just to go poking around unless I've got a pretty good idea of what is or isn't possible beforehand. Thanks in advance!

No, RAID 1 is two disks, no more no less. You may be able to reconfigure the virtual disk to another RAID level by adding more physical disks.

So, way down at the bottom of this post:

This guy claims to have done exactly that - reconfig from RAID 1 to RAID 5 on a Perc 710 with no reboot or data loss. Would the same be possible on that 730?
