Drobo mounts, but can't access data

Hi! I’m in a pickle and hope someone can help.

I picked up a new-ish Mac mini and am moving my Drobo over. When I plug it in, the drive will mount as a generic drive. It sees the Time-Machine partition, but won’t show the Drobo with the standard Drobo icon and only a generic drive icon. It also doesn’t appear in the Drobo Dashboard. If I double-click the generic drive Drobo, it will hang the Finder. If I try to unmount it in Disk Utilities, it will hang there, too.

Any recommendations? I have people who are waiting to access this drive and are depending on me. Hopefully I can figure something out.
