My volume does not go up

My Mac MINI Catalina setup with a drobo 5d3 (4.2.3 [14.53.116068]). My drobo boots normally. All lights are ok. It is visible in the dashboard. The volume is present with a correct capacity. however, I don’t see my volume in the Finder. Does anyone know how to mount my volume and find my data?
Thank you.

Hello,

Not at all. My volume is present on the dashboard but absent in the finder.
