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
I/O module in the Data Domain system change from off to blue or green.
If any of these LEDs stays off or is not running at normal speed, it means there
is a problem in the connection between the system and the shelf. See the
section
on page 11 for more information. Reseat or
replace the cable and check the LEDs again. If the connection still has a
problem, replace the controller module or the SAS I/O module.
Verifying shelf installation
The Data Domain system recognizes all data storage (system and attached shelves) as
part of a single file system volume.
WARNING
l
Do not remove or disconnect a shelf that has been added earlier. If a shelf is
disconnected, the file system volume is immediately disabled and all data in
the volume is lost.
l
To re-enable a shelf, reconnect the shelf or transfer the disks from the shelf
to another empty shelf chassis and connect.
l
If the data on a shelf is not available to the file system volume, the volume
cannot be recovered.
l
Unless the same disks are available to the file system, the DD OS must be re-
installed as directed by your contracted service provider or Online Support
site,
.
Procedure
1. After installing the new shelves, check the status of the SAS I/O module by
entering the
disk port show summary
command:
