Per updates notes on Firmware ver 25.3.0.0016 (link), the PERC H830 now supports online capacity expansion (OCE) of RAID10 volumes with less than 32 disks. Our card is at firmware 25.5.x.

The drives show up as "Ready" in the PERC but there is no "Reconfigure..." option available in OpenManage or in the controller BIOS. The ability to do this is also referenced in the users guide (link).
