Linux + how to simulate JBOD disks that are out of service in shelf

We have Kafka machines installed with RHEL 7.2 servers on Dell HW and a shelf includes 15 disks. We want to understand what happens when we push out one of the Kafka disks, and see if Kafka is still functional. So the easy solution is just to push out the disk from the shelf. But is it possible to simulate this situation without pushing out the disk? For example we can umount the disks from the mount point, but this isn't enough good like pushing out the disks from the shelf.
