Original GitHub issue: https://github.com/007revad/Synology_HDD_db/issues/285

Originally assigned to: @007revad on GitHub.

I have a RS3621xs+. I installed a 25G network card on the device. So I only have one pcie expansion slot left. But I want to install 4 m2 SSDs.
I found that the official E10M20-T1 expansion card uses the ASM2824 chip. At the same time, many third-party 4-bay m2 expansion cards also use the ASM2824 chip. I think these third-party expansion cards can be used with RS3621xs+.
But when I tried to install, I found some problems. My third-party expansion card is correctly recognized by the underlying linux system.I can see the expanded pcie channel in ssh. And the syno_hdd_db.sh script log also shows the correct m2 hard disk information. This is the log of the last run:

You may need to reboot the Synology to see the changes.

But in DSM's storage manager, I can't find any m2 SSD.

I also tried the syno_enable_m2_card.sh script. It returned the following information:

Synology_enable_M2_card v3.1.15
RS3621xs+ DSM 7.2.1-69057-5 

StorageManager 1.0.0-0017

RS3621xs+: No PCIe x8 slot found!

What should I do to make DSM recognize my m2 expansion card correctly? Or I have to use official expansion cards.

I'm curious why syno_enable_m2-card thought your RS3621xs+ has no PCIe x8 slots.

What does the following command return?

sudo dmidecode -t slot | grep "PCI Express x8"

If that command returns nothing can you reply with what this command returns:

sudo dmidecode -t slot

Does "Control Panel > Info Center" show for "PCIe Slot 1" and "PCIe Slot 2"?

You could this:

sudo set_section_key_value /usr/syno/etc.defaults/adapter_cards.conf FX2422N_sup_nvme rs3621xs+ yes

I tried running the "sudo set_section_key_value /usr/syno/etc.defaults/adapter_cards.conf FX2422N_sup_nvme rs3621xs+ yes" command and restarted, but it had no effect.

In your screenshot for "PCIe Slot 2" what does that translate to in English?

Can you try this, with a capitol RS:

sudo set_section_key_value /usr/syno/etc.defaults/adapter_cards.conf FX2422N_sup_nvme RS3621xs+ yes

You might need to reboot after that.

The screenshot shows that pcie slot 2 is "occupied". This command still had no effect (I restarted after executing it.).

Sadly I don't think your PCIe card is going to work.
