Thanks for the suggestions
Unfortunately, I do not have (yet) an HBA.
There are 420 working on the server (gen8).
The installed operating system is Windows Server 2016 (Hyper-V) and must remain so.
There are no problems in ILO4. Only after a failure the system signals an error identical to that in the post 1812, April 30, 2019.
Three SSDs 512 GB (RAID 5) and 8 x 4 TB are installed. RAID 6,
4TB drives are from different manufacturers (Seagete, WD). This is probably the cause of my problems.
I recommend the article

Its author has collected some interesting and very useful information about problems with "foreign" disks on HP servers.
