Synology enable M2 card

Description

Enable Synology M.2 PCIe cards in Synology NAS that don't officially support them

Allows using E10M20-T1, M2D20, M2D18 or M2D17 cards in Synology NAS models that aren't on their supported model list.

Enables E10M20-T1, M2D20, M2D18 and M2D17 for DS1823xs+, DS1821+, DS1621+.
Enables M2D18 and M2D17 for DS2422+, RS2423+, RS2421+, RS2421RP+, RS2821RP+.
Enables M2D18 and M2D17 for RS822RP+, RS822+, RS1221RP+ and RS1221+ using DSM 7.1.1 and older.
May enable E10M20-T1, M2D20, M2D18 and M2D17 for other models with a PCIe x8 slot that have /usr/syno/synonvme.

Synology HDD db now enables using Storage Manager to create volumes on M.2 drives in a PCIe M.2 adaptor card.

Which Synology models will this work on

Works on the following models:

Notes

Synology added support for the M2D18 in RS822+ and RS1221+ in DSM 7.2
E10M20-T1 needs 1cm cut off to fit into a RS2418RP+/RS2418+

Other Models Notes

The Synology must have a PCIe x8 slot
DSM must include /usr/syno/bin/synonvme
DSM must include /usr/lib/libsynonvme.so.1

Should work for the following models but I have not tested them:

How to run the script

Download the script

Download the latest version Source code (zip) from https://github.com/007revad/Synology_enable_M2_card/releases
Save the download zip file to a folder on the Synology.
- Do NOT save the script to a M.2 volume. After a DSM or Storage Manager update the M.2 volume won't be available until after the script has run.
Unzip the zip file.

Running the script via SSH

How to enable SSH and login to DSM via SSH

Note: Replace /volume1/scripts/ with the path to where the script is located. Run the script then reboot the Synology:

sudo -s /volume1/scripts/syno_enable_m2_card.sh

Options:

  -c, --check           Check M.2 card status
  -r, --restore         Restore from backups to undo changes
  -e, --email           Disable colored text in output scheduler emails.
      --autoupdate=AGE  Auto update script (useful when script is scheduled)
                        AGE is how many days old a release must be before
                        auto-updating. AGE must be a number: 0 or greater
      --model=CARD      Automatically enable specified card model
                        Required if you want to schedule the script
                        CARD can be E10M20-T1, M2D20, M2D18 or M2D17
  -h, --help            Show this help message
  -v, --version         Show the script version

What about DSM updates?

After any DSM update you will need to run this script again.

Schedule the script to run at shutdown

Or you can schedule Synology_enable_M2_card to run when the Synology shuts down, to avoid having to remember to run the script after a DSM update.

See How to schedule a script in Synology Task Scheduler
