Is it possible to rebuild RAID 5 with 1 disk and controller failure?

Question

Iron

Essence of the question:
There was an HP server with an MSA60 shelf connected to it via a SAS cable (11 HDD RAID5 + 1 HDD HotSpare). The controller to which the shelf is connected is HP SmartArray P411i.
Last week, this construct did not successfully return from reboot due to the impossibility of initializing the array. According to the iLO logs, the MSA60 is the culprit.
As a replacement, a Supermicro server with an AVAGO MegaRaid 9361-4i controller (former LSI) was purchased and the task was to transfer the array from MSA60 to Supermicro, of course, with all data preserved.
The situation at the moment - all HDDs are connected to MegaRaid 9361, one of them is immediately determined by the controller as faulty (and the above-mentioned HotSpare was used up while the MSA60 was still alive).
And here is the question (purely theoretical) what are the chances of extracting data from these disks? And how can you check it?

Answer 1

A purely theoretical question: are there any backups?
Information recovery firms will help you. If the infa is valuable and there are no backups, it's better not to experiment yourself. 10 discs are still alive?
