How to mount in ubuntu raid fake?

Question

linux

Good afternoon, dear experts! I'm sorry. that distract you from your affairs. But I need advice, my experience is not enough.
The situation is this, fakeraid is used on the motherboard https://www.supermicro.com/products/motherboard/xe... .
There are 4 hard drives, 2 ssds and 2 hdds. Through the utility built into the motherboard, 2 raids of the 1st level were raised.
Installing ubuntu goes on a raid SSD, everything goes well, the system installs. The question is how to mount a raid which is on the HDD?
PS. the author of the post understands that it is better to make a soft raid, but alas, the author's manuals do not recognize him.
sudo blkid:

Thank you in advance for your help!

Answer 1

isw_dhfhegacbi_Volume1 seems to be that second fake array. Apparently, the partition table was not found on it.
