It seems PERC H730P's device ID is 0x005d.

	https://pci-ids.ucw.cz/read/PC/1000/005d

It's the Invader series. I have Fujitsu PRAID EP400i. It's also Invader.
It works with one of my machines, but it doesn't guarantee that
your machine with PERC H730P works. Some people reported that kern/56669
(and perhaps kern/55192) still exist on some systems :-(

bioctl mfi(i)X show

Maybe. If your machine's battery_type is 1, 2, 5 or 6, you can do by envstat(8).

#define MFI_BBU_TYPE_IBBU       1
#define MFI_BBU_TYPE_BBU        2
#define MFI_BBU_TYPE_IBBU09     5
#define MFI_BBU_TYPE_CVPM02     6

If your system has other number, please let me know.
