DS920+ MaxDisks issue

[GunterO]

Is there a way to extend the nr of disks?
Thinks I tried:
Altered /etc/synoinfo.conf & /etc.defaults/synoinfo.conf
maxdisks="16"
internalportcfg="0xffff"
Checked user_config.json, and looks good:
"synoinfo": {
"internalportcfg": "0xffff",
"maxdisks": "16",
"support_bde_internal_10g": "no",
"support_disk_compatibility": "no",
"support_memory_compatibility": "no"
},

DSM is showing this:

However, the 5 drives are visible:

So, is this just a GUI issue?

DS920 uses DTS (Device Tree Source),satamap is invalid for it

How many disks do you have in total ?

Currently 4 HDD's (for SHR) an one SSD. But I want to add more HDD's to the SHR later, and I'm worried that it won't work because it is only showing 4 drives (see screenshots).
