Chapter 1: Installation Roadmap for the Disk Shelf 3

Before you begin your installation

About disk shelf installation

Disk shelf numbering

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

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.

Shelf 1

Drive Bays

013

45678910111213 3 2 1 0

Loop ID 29 - 16

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-cy cle the disk shelf.

4 Before you begin your installation

Shelf ID switch

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.

Replacing a disk shelf in a rack

Installing a disk shelf in a rack

Installing a disk shelf

To install the disk shelf in a rack, complete the following steps.

DANGER

You must install each disk shelf with either the two-post telco tray kit or the fourpost rail kit that came in your shipment package. If you choose to mid-mount the disk shelf, use the mid-mount brackets with the two-post telco tray kit. Do not ear-mount the disk shelf into a telco-type rack; the disk shelf will collapse from the rack under its own weight.

Step Action

1 Verify that your system meets the minimum software requirements to

support the disk shelf. See the System Configuration Guide at

http://now.netapp.com for more information.

2 Verify that you received the envelope with the disk shelf ID labels. 3 Ground yourself to the system chassis using the grounding leash. 4 Use the rail kit installation flyer in the rail kit box to inst all the

appropriate rail kits on the rack.

5 Install and secure the disk shelf onto the support brackets and rack. 6 Change the disk shelf ID with the following procedure:

1. Press the thumbwheel switch on the rear of the disk shelf and use

the + button to raise the number and the - button to lower the number to a valid ID from 1 through 7.

2. 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.

3. Select the correct label from the env elope identif ied in Step 2 and

attach it to the right flange of the new disk shelf.

7 If you are adding multiple disk shelves on the same loop, repeat Step 5

and Step 6 to install the remaining disk shelves.

38 Replacing a disk shelf

Step Action

8 Set the loop speed:

◆ The 1-Gb loop speed setting must be used if the loop is connected

to a FAS270.

◆ The 2-Gb loop speed setting must be used if there is any

component on any part of the loop that is only capable of 2-Gb operation. Examples of these components are the DS14mk2FC, SFPs, HBAs, or drives.

◆ For the 4-Gb loop speed setting to be used, all components on any

part of the loop must be of 4-Gb capable. Examples of these components are this disk shelf model, SFPs, HBAs, or drives.

Attention

An incorrectly set loop speed causes the system to panic.

9 Use the appropriate cable to connect both modules of the disk shelf to

the other disk shelves or to your system. See “Disk shelf cabling

requirements” on page 32 for additional requirements.

10 Connect the two disk shelf power cords to each disk shelf that you are

adding.

11 Turn on the power first to the disk shelves and then to the system. 12 Reboot the system.

Replacing a disk in a disk shelf

Reasons to replace a disk

Preparing to replace a disk

About replacing a disk in a disk shelf

You can replace a disk in a disk shelf for any reason. However , the most common reason is disk failure. If a disk fails, the system logs a warning message to the system console indicating which disk on which loop failed.

In addition, a disk shelf with an ESH2/ESH4 module identifies any one of the following situations as disk failure:

◆ A disk is bypassed.

◆ The system boots with the presence of bypassed disks.

◆ The system detects an eminent threshold bypass.

The following autosupport warning message is then sent:

DISK FAIL!! - Bypassed by ESH

Before you replace a disk in a disk shelf, you must first check the disk shelf to ensure that after you remove the disk you still have enough disks installed to meet the enclosure services requirements. For information about these requirements, see “Drive bay requirements” on page 7.

Replacing a disk in a disk shelf consists of the following procedures:

◆ “Removing a disk” on page 41

◆ “Installing a disk” on page 43

Note

If you are replacing several disks in a disk shelf or if you are installing several disks into a half-empty disk shelf, replace or install the disks one at a time to allow your system to recognize the existence of each new disk.

Replacing an ESH2/ESH4 module

Hot-swapping a module

Assumptions about this procedure

Hot-swapping a module

The assumptions about this procedure are that you are replacing either one or both modules of a single disk shelf, that the modules on the disk shelf have multipath connections to the system, and that you are hot-swapping one of the following:

◆ An ESH2 with another ESH2

◆ An ESH2 with an ESH4

◆ An ESH4 with another ESH4

Note

A hot-swap of an ESH2 with an ESH4 requires that you perform a minimum upgrade to Data ONT AP 6.4.4 or later and replace both modules in the disk shelf.

Depending on the module or modules you are hot-swapping and their position in the loop, you might need to order additional cables appropriate to the modules. See “Disk shelf cabling requirements” on page 32 for additional requirements.

Attention

If you attempt to hot-swap the module on a disk shelf that does not have multipath connections, you lose all access to the drives on this disk shelf as well as those below it.

For detailed information

Appendix A: Hot-adding a Disk Shelf to an Existing System 55

For detailed information about hot-adding a disk shelf, see the following topics:

◆ “Hot-adding a disk shelf to an existing loop” on page 57

The modules on the disk shelf detected a speed mismatch between the preceding disk shelf and this disk shelf and is reporting them as automatic terminate errors.

One of three reasons cause this error message to appear:

◆ The shelf-to-shelf cable between the now second-to-

last disk shelf and the newly added disk shelf is defective or is not securely fastened.

◆ The speed of the newly added DS14mk2 FC/

DS14mk4 FC disk shelf is incorrectly set.

One of two reasons cause this error message to appear:

Hot-adding a disk shelf to an existing loop

To hot-add a disk shelf to an existing loop, complete the following steps.

Note

To hot-add disk shelves to a High availability or Active/active configuration, see the High-Availability Configuration Guide or the Active/Active Configuration Guide.

Step Action

1 V erify that your system meets the minimum software requirements to

support the disk shelf and module combination. See the System Configuration Guide at http://now.netapp.com for more information.

2 Verify that you received the en velope with the disk shelf ID labels. 3 Ground yourself to the system chassis using the grounding leash. 4 Use the rail kit installation flyer in the rail kit box to install the

appropriate rail kits on the rack.

5 Install and secure the disk shelf onto the support brackets and rack. 6 If you are adding multiple disk shelves on the same loop, repeat Step

4 and Step 5 to install the remaining disk shelves in ascending

numerical order, according to the IDs on their labels.

7 Connect the grounding strap connecting the disk shelf to the other

disk shelves or your system.

Appendix A: Hot-adding a Disk Shelf to an Existing System 57

Step Action

8 Set the loop speed:

◆ The 1-Gb loop speed setting must be used if the system is an

F AS270.

◆ The 2-Gb loop speed setting must be used if there is any

component on any part of the loop that is only capable of 2-Gb operation. Examples of these components are the DS14mk2FC, SFPs, HBAs, or drives.

◆ For the 4-Gb loop speed setting to be used, all components on

any part of the loop must be of 4-Gb capable. Examples of these components are this disk shelf model, SFPs, HBAs, or drives.

Attention

An incorrectly set loop speed causes the system to panic.

9 Connect the two disk shelf power cords of each disk shelf that you

are adding to a power source.

Attention

Do not turn on the power to the disk shelf yet.

Recommended Power Line Sizes

About this appendix This appendix describes how to determine the power line lengths running from

the system to the power source.

Topics in this appendix

This appendix discusses the following information:

◆ “Recommended AC power line sizes” on page 68

◆ “Calculating the length of DC wires” on page 69

Appendix B: Recommended Power Line Sizes 67

Recommended AC power line sizes

About AC power feeds

Longer AC power feeds need to be properly designed to preserve voltage levels to the equipment. The wiring from the breaker panel to the power strip, which supplies power to the system and disk shelves, can often exceed 50 feet.

Note

Total AC wire length = breaker to wall or ceiling outlet + extension cable or ceiling drop.

The following table lists the recommended conductor size for 2% voltage drop for a particular distance in feet (taken from the Radio Engineer’s Handbook).
