Hot-adding a disk shelf to an end of a
stack that has multipath HA, multipath,
quad-path HA, or quad-path connectivity
to the controllers
a. Disconnect any cables from IOM A of the disk shelf at the
end of the stack that are connected to any controllers;
otherwise, go to substep e.
Leave the other end of these cables connected to the
controllers, or replace cables with longer cables if needed.
b. Cable the shelf-to-shelf connection(s) between IOM A of
the disk shelf at the end of the stack and IOM A of the disk
shelf you are hot-adding.
c. Reconnect any cables that you removed in substep a to
the same port(s) on IOM A of the disk shelf you are hot-
adding; otherwise, go to the next substep.
d. Verify that all cables are securely fastened.
e. Repeat substeps a through d for IOM B; otherwise, go to
Step 4.
Hot-adding a disk shelf to an end of the
stack in a HX2000 single-path HA or
single-path configuration
These instructions are for hot-adding to
the end of the stack that does not have
controller-to-stack connections.
a. Cable the shelf-to-shelf connection between IOM A of the
disk shelf in the stack and IOM A of the disk shelf you are
hot-adding.
b. Verify that the cable is securely fastened.
c. Repeat applicable substeps for IOM B.
4. If you hot-added a disk shelf with mini-SAS HD SAS optical cables to a stack of disk shelves connected with
SAS copper cables, replace the SAS copper cables; otherwise, go to the next step.
The stack must meet the requirements stated in the “Requirements for hot-adding disk shelves with IOM12
modules” section of this procedure.
5. Download and run Config Advisor to verify that your SAS connections are cabled correctly.

If any SAS cabling errors are generated, follow the corrective actions provided.
6. Verify SAS connectivity for each hot-added disk shelf: storage shelf show -shelf shelf_name
-connectivity
You must run this command for each disk shelf you hot-added.

(port pair 1a/0d) on each controller:
cluster1::> storage shelf show -shelf 2.5 -connectivity
