3. If you are hot-adding one or more disk shelves to an end—the logical first or last disk shelf—of an existing
stack, complete the applicable substeps for your configuration; otherwise, go to the next step.
If you are...
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
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.
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.
Fujitsu Downloads: Config Advisor
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.
For example, the following output shows hot-added disk shelf 2.5 is connected to initiator ports 1a and 0d
(port pair 1a/0d) on each controller:
cluster1::> storage shelf show -shelf 2.5 -connectivity
Shelf Name: 2.5
Stack ID: 2
Shelf ID: 5
Shelf UID: 40:0a:09:70:02:2a:2b
Serial Number: 101033373
Module Type: IOM12

Then...
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.
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.
