Synology enable eunit

Description

Enable unsupported Synology eSATA and InfiniBand Expansion Unit models

This script will allow enabling:

• DX517, DX513, DX213, DX510, RX418, RX415 or RX410 on Synology NAS that have an eSATA port.
• RX1217RP, RX1217, RX1214RP, RX1214, RX1211RP, RX1211, DX1215II, DX1215 or DX1211 on Synology NAS that have an InfiniBand port.

You can enable as many different expansion unit models as you want.

If you have 2 of the same expansion unit model you only need to enable it once for both expansion units to be enabled in DSM.

Warning
Do NOT span a storage pool between the NAS and Expansion Unit. After a DSM update the Expansion Unit will be unsupported until you run this script again, which will be hard to do if your only storage pool is offline. Also do NOT store this script on a volume in the expansion unit.

How to run the script

Scheduling the script in Synology's Task Scheduler

See How to schedule a script in Synology Task Scheduler

Run the script via SSH

How to enable SSH and login to DSM via SSH

Run the script then reboot the Synology:

sudo -s /volume1/scripts/syno_enable_eunit.sh

Note
Replace /volume1/scripts/ with the path to where the script is located.

Options:

  -c, --check           Check expansion units status
  -r, --restore         Restore from backups to undo changes
      --unit=EUNIT      Automatically enable specified expansion unit
                          Only needed when script is scheduled
                          EUNIT is dx517, dx513, dx213, dx510, rx418, rx415,
                          rx410, rx1217rp, rx1217, rx1214r, rx1214, rxX1211rp,
                          rx1211, dx1215ii, dx1215 or dx1211
  -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
  -h, --help            Show this help message
  -v, --version         Show the script version

What about DSM updates?
