My Drobo is beeping

Hi, I have a Drobo for almost 5 years and last month I had a drive failure. I did the procedure and It restored everything and then I formatted it. But now, it keeps beeping every now and then. Last week it came up with a message that I needed to backup because my Mac couldn’t fix the partition. I Formatted again and it still keeps beeping. Can anyone help me out?

This is the model:
Model - DDR3A
Product Name - Drobo (Gen 3)
