Appendix A: Hot-adding a Disk Shelf to an Existing System

Connect the other end of the cable to the module B Input on the new
disk shelf.

Verify that all the cables are securely fastened.

Attention

Poorly secured cables cause the system to panic over an open loop.

Result:

In 60 seconds, the system recognizes the hot-added disk

shelf.
