Rockstor 3.8.14 installation on RAID volume on HP Proliant Microserver gen8

Thank you for the advices.
I tried a number of solutions.
The closest one with RAID support was to manually extract the RPM from the DD file with cpio tool, and then on Rockstor boot I copied the files from RPM into the loaded system.
What I did:

  1. When Rockstor welcome screen appears, press TAB and add “modprobe.blacklist=ahci” at the end of “vmlinuz …” line
  2. Wait for the kernel to load.
  3. Wait for the setup screen to appear.
  4. Connect the USB containing the extracted folders from RPM file
  5. Press CTRL+ALT+F2
  6. fdisk -l --> find the USB device /dev/sdX
  7. mkdir /media/
  8. mount /dev/sdX /media/
  9. cp -r /media/etc/* /etc/
  10. cp -r /media/lib/modules/3.10.0*/extra/hpvsa/ /lib/modules/3.10.0*/extra/
  11. depmod -a
  12. modprobe kpvsa
  13. fdisk -l --> check if the RAID logical volume is properly found
  14. ps -ef | grep tmux
  15. Kill the process : /usr/bin/tmux -u -f /usr/share/anaconda/tmux.conf start
  16. The Anaconda Installer should re-initiate and the RAID volume should be there.

The installation successfully finishes, after reboot GRUB is loaded but on Linux startup, it hangs at dracut and I could have the dracut shell.
Any ideas to further troubleshoot this is highly appreciated.

Though, I managed to install Rockstor on SSD (in AHCI mode) with bootloader installed on the internal SD card. I did not change anything in BIOS, RAID support being active.
