Windows – HP DL 360G7 and HP smartarray P410i RAID 1 troubleshooting

This should be an old story, but it happened just couple weeks ago.
System is as in the topic, with two disks in RAID1, one day one of the disks fell off. I ordered new disks for future use and continued work.

Couple of days after a failure, I looked on HP ACU and I wasn't happy. It said:

Code 730 146GB 1-Port SAS Drive at Port 1I: Box 1 Bay 2 is a part of a logical drive that is not supported by the current configuration. Any configuration command (e.g. logical drive creation, array expansion, etc.) or modification to the controller will result in the loss of all existing data on the disabled logical drive(s).

Does that mean that on that "new" disk was something else? Was that owerwritten by a RAID rebuild?

Short after that (week and a half) second disk failed. I looked in the ILO and there was another information in Integrated Management Log:

POST Error: 1786-Drive Array Recovery Needed
POST Error: 1747-Slot X Drive Array – Unsupported Array Configuration Detected – More logical drive(s) configured than this controller model can support. All logical drive(s) have been disabled.

What does that actually mean? System was not restarted since then.
I would be glad if someone explained. Guess it is time to change that ol' scrap, but …you know. Beer is on me 😉

edit:
heres the config:
