As per the title everything went great during the red pill setup.
2 virtual hard drives for testing purposes, setup as SATA controller, and LSI Logic Parallel
It appears DSM doesn't like something, but it sees the hard drives.
Any help will be appreciated. Thanks!
Figured out the issue, in the end it was due the Size of the HDD, compared to DSM 5x/ DSM 6.x, in DSM 7.x the minimum HDD size must be 21 GB or larger as per
after adjusting the HDD sizes, then it worked just fine.
