Hello,
I installed Rocky Linux 9.6 on a server with six physical disks: two SAS, two SATA SSD and two NVMe.
The SAS and SATA SSD disks are connected to a physical RAID controller. I created two RAID groups for these disks and installed the OS.
The NVMe disks have a RAID group created based on Intel VROC.
After installing the OS, I ran the ‘fdisk -l’ command, and the results are as follows:

I found the following article, but I’m not sure if this is normal behaviour when RAID is configured based on Intel VROC: After building RAID in RSTe mode (IMSM), there will be an error when executing partprobe - Red Hat Customer Portal
Thank you in advance for your help!
