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 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.
