OMV WebUI shows one HDD instead of 2 (I tried the tutorial method)

Hello,

I recently acquire a SATA HAT for my Rpi. Instead of all my efforts, the webUI of OMV only shows one of the two HDD I installed.

Here is the lsusb result:

‘’’
Bus 002 Device 002: ID 1058:0a10 Western Digital Technologies, Inc.
Bus 002 Device 003: ID 1058:0a10 Western Digital Technologies, Inc.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
‘’’

and the lsblk result:

‘’’
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1.8T 0 disk
sdb 8:16 0 1.8T 0 disk
mmcblk0 179:0 0 14.9G 0 disk
├─mmcblk0p1 179:1 0 256M 0 part /boot
└─mmcblk0p2 179:2 0 14.6G 0 part /
‘’’

Can you help?

Thanks for your time and help,
Athena
