4Before you begin your installation
Before you begin your installation
About disk shelf
installation 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
◆Drive bay requirements
Disk shelf
numbering Each disk shelf in a loop must have a unique ID. A valid shelf ID is from 1 through 7, with disk shelf 1 connected to the system. 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 must 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.
Attention
If you change a disk shelf ID, you must power-cycle the disk shelf for the new ID
to take effect. The disk shelf ID display on the front of the disk shelf blinks until
you power-cycle the disk shelf.

Chapter 1: Installation Roadmap for the Disk Shelf 5
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 FC with the disk
shelf ID set to 1.
Loop IDs In addition to identifying the disk shelf ID and the direction of the drive bays, the
ID label on the right side of the disk shelf includes the loop ID. The loop ID
identifies the disks in the disk shelf. The last sheets of the quick reference cards
that come with your disk shelf shows the seven disk shelf IDs and their
corresponding loop IDs.

Supported disk
drives See the System Configuration Guide at http://now.netapp.com for more information on supported drives and platforms.
Drive bay
requirements For enclosure services monitoring to work, drive bays 0 and 1 must contain a disk.
This requirement is posted on the label on the left flange of the disk shelf. The 14
drive bays in the disk shelf are numbered 0 through 13 from right to left, as
shown in the following illustration.

8Before you begin your installation
The system uses the enclosure services monitoring method to monitor
environmental conditions of the disk shelf. Enclosure services conditions are
communicated to the system through the ESH2 or ESH4 module.
The following table describes the three stages of enclosure services monitoring.
Stage Device What it does...
1System Uses a subset of SCSI-3 commands to monitor the
disk shelf for data related to disk presence,
temperature, power supply units, and fan status.
2System Sends the commands through its Fibre Channel
interface to drive bays 0 and 1 on the disk shelf.
3Drive bays 0
and 1 Communicate the request to the ESH2 or ESH4 module and send the data to the system.
ESH2 or ESH4
module Collects the requested data and sends it to drive bays 0 and 1.

Monitoring the front operation panel
About monitoring
the front operation
panel
The front operation panel has five LEDs and a disk shelf ID display. The LEDs
indicate whether your disk shelf is functioning normally or there are problems
with the hardware. You can also identify any hardware failure associated with the
front operation panel of the disk shelf from the error messages displayed on your
system console.
Location of LEDs The following illustration shows the location of the disk shelf ID display and the
front panel LEDs.
Note
The Fault and System LEDs are amber. The other three LEDs are green. See
“LED status on the front operation panel” on page 13 for an illustrated
explanation of how the LEDs function.
Monitoring the disk
shelf ID When you use the thumbwheel switch on the back of the disk shelf to change the disk shelf ID, the disk shelf ID display on the front panel blinks until you power-
cycle the disk shelf to make the change take effect.
