Tutorial: Install DSM 7.1 on UNRAID 6.10.3

This tutorial is a supplement to the ESXi TCRP installation tutorial located here:




Installing DSM 7.1.0.-42661 on UNRAID 6.10.3


I have been trying to install DSM 7.1 on my unraid server for the last night. After some problems and testing I have created this guide to install DSM 7.1 on UNRAID working perfectly.


This is my vm config:





STEP 1-Virtual machine creation: 

  •     Download tiny core from https://github.com/pocopico/tinycore-redpill
  •     Select CentOS VM Template and apply correct options from the attached image.
  •     Select Q35-6.2
  •     Select 3.0 (qemu XHCI)
  •     Load tiny red core as vdisk1 USB by selecting manually (you can create previously the name of the folder for the VM inside /domains and upload the tinycore img )
  •     Create secondary disk 50G or whatever you want (this is your data storage for synology) as vdisk2 SATA
  •     Select Network model: e1000
  •     Save.
  •     Uncheck "Start VM after creation"

  •     Edit again vdisk2 in the advanced xml template (top right corner) to controller='1' (if we don't do this tiny red core will not detect the disk properly when doing the satamap and will not install DSM correctly and will ask you to reinstall the *.pat infinitely)


STEP 2-Start VM and connect via SSH


  •     Start VM and load tiny red core
  •     Once the OS is loaded, open the terminal and enter ifconfig to find out the ip of the machine
  •     Connect via ssh (with Putty) to the obtained IP address.

        user: tc
        password: P@ssw0rd



STEP 3-Run the following commands:


  •     To update tiny red core with the latest data 


./rploader.sh update now
./rploader.sh fullupgrade now


  •     To generate random mac and serial numbers (copy mac address generated to set on unraid vm template later)


./rploader.sh serialgen DS918+ (or whatever version you want, you can see all versions available with command info ./rploader.sh)


  •     To map the connected disks


./rploader.sh satamap now


  •     To record the vid/pid from usb


./rploader.sh identifyusb now



  •     To install NIC drivers (sometimes it loads the e1000e module instead of the e1000 and it doesn't work, adding this command will make sure that the e1000 module for the NIC is loaded correctly)


For e1000 Network Card run:


./rploader.sh ext apollolake-7.1.0-42661 add https://raw.githubusercontent.com/pocopico/rp-ext/master/e1000/rpext-index.json

NOTE: change version according your selection for CPU and DSM version


For virtio-net Network Card run:


./rploader.sh ext apollolake-7.1.0-42661 add https://raw.githubusercontent.com/pocopico/rp-ext/master/v9fs/rpext-index.json

NOTE: change version according your selection for CPU and DSM version


  •     To build the image


./rploader.sh build apollolake-7.1.0-42661


STEP 4-Download your .pat for your correct cpu architecture from official repo or mega download for this version apollolake , we will need it to install DSM later.


https://global.download.synology.com/download/DSM/release/7.1/42661-1/DSM_DS918%2B_42661.pat - Offical repo


STEP 5-Edit VM settings on advanced xml mode and install *.pat


  • After doing all the above we shut down the machine.
  • Edit the virtual machine on xml advanced mode (if we change mac address in normal editing mode you will lose controller="1" option set for vdisk2 we did previously so you will have to set it again everytime you change and/or save a setting from normal mode, try to edit always in xml advanced mode), look for MAC address and set the MAC generated by tiny red core.
  • Save
  • Start VM
  • Select the first option USB and leave it a few minutes until we find it with synology assistant


  • Open WebGui and install *.pat


We now have DSM 7.1 working on unraid.

There is other method with SATA boot but I have to test it better.


Hope this guide help someone.
