Information you
need to understand
Before you install one or more disk shelves in a rack, you need to understand the
following information:
◆
Disk shelf numbering
◆
Loop IDs
◆
Supported disk drives
Disk shelf
numbering
Each disk shelf in a loop must have a unique ID. A valid shelf ID is from 1
through 6, with disk shelf 1 connected to the storage appliance. The default for an
invalid shelf ID is 7. If you install a second or third loop of disk shelves, the disk
shelf IDs in each loop must start at 1. The ID of a single disk shelf should be 1.
Each disk shelf is shipped with its assigned ID set on its back panel. You must
ensure that the disk shelf has the correct ID number on the label. The ID label is
on the right side of the disk shelf, as shown in the following illustration.
NetApp sets the disk shelf IDs at the factory on configured systems, using an ID
switch on the back panel. If you order additional disk shelves, you must set the
disk shelf ID yourself.
Note
If you enter a shelf ID that is not from 1 through 7, the drive addresses default to
those of a shelf with the ID switch set to 7 even though the shelf ID indicator in
the front operation panel displays a dash (-).
The example in the following illustration shows a DS14mk2 AT with the disk
shelf ID set to 1.
