Possible loss of data access: Never slam the drawer shut. Push the drawer in slowly
to avoid jarring the drawer and causing damage to the storage array.
h. Close the drive drawer by pushing both levers towards the center.
i. Repeat these steps for each drawer in the disk shelf.
4. If you are adding multiple disk shelves, repeat the previous steps for each disk shelf you are installing.
5. Connect the power supplies for each disk shelf:
a. Connect the power cords first to the disk shelves, securing them in place with the power cord retainer,
and then connect the power cords to different power sources for resiliency.
b. Turn on the power supplies for each disk shelf and wait for the disk drives to spin up.
6. Set the shelf ID for each disk shelf you are hot-adding to an ID that is unique within the HA pair or single-
controller configuration.
If you have a system with an internal disk shelf, shelf IDs must be unique across the internal disk shelf and
externally attached disk shelves.
You can use the following substeps to change shelf IDs, or for more detailed instructions, use
Change a
shelf ID
.
a. If needed, verify shelf IDs already in use by running Config Advisor.
You can also run the
storage shelf show -fields shelf-id command to see a list of shelf IDs
already in use (and duplicates if present) in your system.
b. Access the shelf ID button behind the left end cap.
c. Change the shelf ID to a valid ID (00 through 99).
d. Power-cycle the disk shelf to make the shelf ID take effect.
Wait at least 10 seconds before turning the power back on to complete the power cycle.
The shelf ID blinks and the operator display panel amber LED blinks until you power cycle the disk
shelf.
e. Repeat substeps a through d for each disk shelf you are hot-adding.
