Synology enable eunit

Description

Enable unsupported Synology eSATA Expansion Unit models

This script will enable a choice of DX517, DX513, DX213, DX510, RX418, RX415 or RX410 on Synology NAS that have an eSATA port.

You can enable DX517, RX418 and a 3rd model of either DX513, DX213, DX510, RX415 or RX410.

Note
If you later want to change the 3rd model you need to:

Run the script with the --restore option.

Run the script again to enable your chosen expansion unit.

Reboot.

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.

I'm not sure if the RS models would only be able to use 4 of the 5 bays in a DX517 if the total drive number exceded the models' max drive number.

For example:

An RS822+ may only see 4 drives in a DX517.
An RS1221+ may only see 8 drives in two DX517.

Supported Models

I'm 99% certain this script will work for the following Synology NAS models:

Model	Works	Commment
DS720+	???
DS723+	???
DS920+	???
DS923+	???
DS1520+	???
DS1522+	???
DS1621+	???
DS1821+	???
DS1823xs+	???
RS822+, RS822RP+	???
RS1221+, RS1221RP+	???

The DiskStation models above already have DX517 enabled, and RX418 partially enabled.
The RackStation models above already have RX418 enabled, and DX517 partially enabled.
