Cabling Disk Shelves With Iom12 Modules For A Hot-Add - Fujitsu ETERNUS AX Series Installation And Cabling Manual

Table 5:
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 HX2000 series system, 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 the procedure
in the "Changing the disk shelf ID" section.
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.

Cabling disk shelves with IOM12 modules for a hot-add

You cable the SAS connections—shelf-to-shelf and controller-to-stack—as applicable for hot-added disk shelves
so they have connectivity to the system.
Before you begin
You must have met the requirements in the "Requirements for a hot-adding disk shelves with IOM12 modules"
section and installed, powered on, and set shelf IDs for each disk shelf as instructed in the "Installing disk
shelves with IOM12 modules for a hot-add" section.
About this task
• For an explanation and examples of shelf-to-shelf "standard" cabling and shelf-to-shelf "double-wide"
cabling, see the "Shelf-to-shelf SAS connection rules" section.
• Instructions about how to read a worksheet to cable controller-to-stack connections can be found towards
the back of this guide.
• After you have cabled the hot-added disk shelves, ETERNUS AX/HX Series recognizes them: disk ownership
is assigned if disk ownership automatic assignment is enabled; disk shelf (IOM) firmware and disk drive
firmware should automatically update if needed; and if in-band ACP is enabled on your configuration, it is
automatically enabled on the hot-added disk shelves.
Note: Firmware updates can take up to 30 minutes.

Attention: 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.
