Running the following system:
Host: Lenovo ThinkSystem SR550 (gen2) with a HW RAID Controller ThinkSystem 5350-8i.
OS: Ubuntu 22.04.01 server
Kernel: 5.15.0-56-generic
The system is supposedly Certified for Ubuntu:
https://ubuntu.com/certified/201904-26967
But, when checking the output of lshw, there is A LOT of UNCLAIMED devices.
Some of which, seem to be sensors and others related to the chipset itself, or some other peripherial.
Output is in Pastebin, because of the char limit:
https://pastebin.com/cNuxhPD5
The i2c-i801 kernel module for the chipset is loaded...
And it does not seem that the RAID controller is recognized as well, despite the Lenovo page saying it is supported in 22.04:

There is currently RAID 1 configured through the HW controller, but not sure if i am supposed to see any modules loaded for it in lsmod:
raid1 49152 0
smartctl returns some data and sees the device as type enclosure.

Which i guess could be attributed to wrong recognition, since its unclaimed?
Network controller (network-0) is also said to be UNCLAIMED, yet network-1 (which is an interface), is claimed and works properly.
Any advices on how should i deal with all those UNCLAIMED devices, and if its actually an issue? Nothing else on the internet specifies anything about this much UNCLAIMED or related to this series of servers.
