2. Expansion (Out), on Controller B
3. Host (In), on Controller B
4. Enclosure address, on Controller A (not used)
5. Power (Green) or Fault (Amber), on Controller A
6. Bus ID, on Controller A
7. Host link active, on Controller A
8. Expansion link active, on Controller A
9. LEDs: Controller A: Power LED, Power fault: Amber, Blower fault: Amber
7. Restart the Data Domain system. As the system boots up, the HOST/
EXPANSION LEDs on the shelf controller ports that are connected to the SAS
HBAs in the Data Domain system change from off to blue or green (see LED
information in Back panel: Power/cooling module and shelf controllers
13).
If any of these LEDs stays off or is not running at normal speed (see the table in
Back panel: Power/cooling module and shelf controllers
there is a problem in the connection between the system and the shelf. Reseat
or replace the cable and check the LEDs again. If the connection still has a
problem, replace the controller module or the SAS HBA.
The Data Domain system recognizes all data storage (system and attached shelves) as
part of a single file system volume.
WARNING
Do not remove or disconnect a shelf that has been added earlier. If a shelf is
l
disconnected, the file system volume is immediately disabled and all data in
the volume is lost.
To re-enable a shelf, reconnect the shelf or transfer the disks from the shelf
l
to another empty shelf chassis and connect.
If the data on a shelf is not available to the file system volume, the volume
l
cannot be recovered.
Unless the same disks are available to the file system, the DD OS must be re-
l
installed as directed by your contracted service provider or the Online
Support site, http://support.emc.com.
