Hot-add - NS224 shelves

You can hot-add an NS224 drive shelf after your HA pair meets certain requirements, and

after the preparation tasks applicable to your HA pair are completed.

Requirements for a hot-add

Your HA pair must meet certain requirements before hot-adding an NS224 drive shelf.

•Your platform model and version of ONTAP must support the NS224 shelf and drives you are hot-adding.

NetApp Hardware Universe

•You must have the correct number and type of cables to connect the shelf.

NetApp Hardware Universe

•Your HA pair must have enough available RoCE capable ports to support the number of shelves you are

hot-adding.

For each shelf you are hot-adding, you need a minimum of two RoCE capable ports on each controller.

These ports can be on board the controllers, on RoCE capable PCIe cards, a combination of both, or on

RoCE capable I/O modules, as supported by your platform model.

If your HA pair does not have enough available RoCE capable ports, and your platform model supports the

use of RoCE capable PCIe cards or I/O modules, you must have installed the additional cards or I/O

modules into the correct controller slots, as supported by your platform model.

NetApp Hardware Universe

Non-dedicated RoCE capable ports must be configured for storage use (not networking

use).

Prepare non-dedicated RoCE capable ports for a hot-add

•If you have an AFF A700 or ASA A700HA pair and you are hot-adding the initial NS224 drive shelf (no

NS224 drive shelf exists in your HA pair), you must have installed a core dump module (X9170A, NVMe

1TB SSD) in each controller to support core dumps (store core files).

Replace the caching module or add/replace a core dump module - AFF A700 and FAS9000

•Your HA pair must have less than the maximum number of shelves supported, by at least the number of

shelves you plan to hot-add.

You cannot have exceeded the maximum number of shelves supported by your HA pair after hot-adding

shelves.

NetApp Hardware Universe

•If you are hot-adding a shelf to an HA pair that already has an NS224 shelf, your HA pair cannot have any

storage cabling error messages, and it must be cabled as multipath HA.

You can run Active IQ Config Advisor to view any storage cabling error messages and the corrective

actions you should take.

•You need a paper clip with one side straightened or a narrow tipped ballpoint pen.

To change the shelf ID, you use the paper clip or ballpoint pen to access the shelf ID button behind the

Operator Display Panel (ODP).

Considerations for a hot-add

You should familiarize yourself with best practices and aspects about this procedure

before hot-adding an NS224 drive shelf.

•Best practice: The best practice is to have the current version of the Disk Qualification Package (DQP)

installed before hot-adding a shelf.

Having the current version of the DQP installed allows your system to recognize and use newly qualified

drives. This avoids system event messages about having noncurrent drive information and prevention of

drive partitioning because drives are not recognized. The DQP also notifies you of noncurrent drive

firmware.

NetApp Downloads: Disk Qualification Package

•Best practice: The best practice is to run Active IQ Config Advisor before and after hot-adding a shelf.

Running Active IQ Config Advisor before hot-adding a shelf provides a snap shot of the existing shelf

Ethernet (ENET) connectivity, verifies NVMe shelf module (NSM) firmware versions, and allows you to

verify a shelf ID already in use in the HA pair. Running Active IQ Config Advisor after hot-adding a shelf

allows you to verify shelves are cabled correctly and that shelf IDs are unique within the HA pair.

NetApp Downloads: Config Advisor

•Best practice: The best practice is to have current versions of NVMe shelf module (NSM) firmware and

drive firmware on your system before adding a new shelf.

NetApp Downloads: Disk Shelf Firmware

NetApp Downloads: Disk Drive Firmware

Do not revert firmware to a version that does not support your shelf and its components.

•After you have cabled a hot-added shelf, ONTAP recognizes the shelf:

◦Drive ownership is assigned if automatic drive assignment is enabled.

◦NSM shelf firmware and drive firmware should be updated automatically, if needed.

Firmware updates can take up to 30 minutes.

Prepare for a hot-add

You must complete the preparation tasks applicable to your HA pair before hot-adding an

NS224 drive shelf.

Prepare non-dedicated RoCE capable ports for a hot-add

If your HA pair has non-dedicated RoCE capable ports that you are using to hot-add an

NS224 drive shelf, you must make sure the ports are configured for storage use (not

networking use). Depending on your platform model, the RoCE capable ports are on

board the controllers, on RoCE capable PCIe cards, a combination of both, or on RoCE

capable I/O modules.

Before you begin

You must have met the system requirements.

Requirements for a hot-add

About this task

•For some platform models, when a RoCE capable PCIe card or I/O module is installed in a supported slot

on a controller, the ports automatically default to storage use (instead of networking); however, it is

recommended that you complete this procedure to verify the RoCE capable ports are configured for

storage use.

•If you determine that the non-dedicated RoCE capable ports in your HA pair are not configured for storage

use, it is a nondisruptive procedure to configure them.

If your HA pair is running a version of ONTAP 9.6, you need to reboot the controllers, one at

a time.

If your HA pair is running ONTAP 9.7 or later, you do not need to reboot the controllers,

unless one or both controllers are in maintenance mode. This procedure assumes that

neither controller is in maintenance mode.

Steps

1. Verify if the non-dedicated ports in the HA pair are configured for storage use. storage port show

You can enter the command on either controller module.

If your HA pair is running ONTAP 9.8 or later, the non-dedicated ports display storage in the Mode

column.

If your HA pair is running ONTAP 9.7 or 9.6, the non-dedicated ports, which display false in the Is

Dedicated? column, also display enabled in the State column.

2. If the non-dedicated ports are configured for storage use, you are done with this procedure.

Otherwise, you need to configure the ports by completing steps 3 through 6.

When non-dedicated ports are not configured for storage use, the command output displays

the following:

If your HA pair is running ONTAP 9.8 or later, the non-dedicated ports display network in

the Mode column.

If your HA pair is running ONTAP 9.7 or 9.6, the non-dedicated ports, which display false

in the Is Dedicated?` column, also display disabled in the State column.

3. Configure the non-dedicated ports for storage use, on one of the controller modules:

You must repeat the applicable command for each port you are configuring.

If your HA pair is

running…

Then…

ONTAP 9.8 or later storage port modify -node node name -port port name -mode

storage

ONTAP 9.7 or 9.6 storage port enable -node node name -port port name

4. If your HA pair is running ONTAP 9.6, reboot the controller module so that the port changes take effect:

system node reboot -node node name -reason reason for the reboot

Otherwise, go to the next step.

The reboot can take up to 15 minutes.

5. Repeat steps for the second controller module:

If your HA pair is

running…

Then…

ONTAP 9.7 or later a. Repeat step 3.

b. Go to step 6.

ONTAP 9.6 a. Repeat steps 3 and 4.

The first controller must have already completed its reboot.

b. Go to step 6.

6. Verify that the non-dedicated ports on both controller modules are configured for storage use: storage

port show

You can enter the command on either controller module.

If your HA pair is running ONTAP 9.8 or later, the non-dedicated ports display storage in the Mode

column.

If your HA pair is running ONTAP 9.7 or 9.6, the non-dedicated ports, which display false in the Is

Dedicated? column, also display enabled in the State column.

Prepare an AFF A700, ASA A700, ASA A800, AFF A800, AFF A400, or ASA A400HA pair to hot-add a

second shelf

If you have an AFF A700, ASA A700, AFF A800, ASA A800, AFF A400, or ASA A400HA

pair with one NS224 drive shelf that is cabled to one set of RoCE capable ports on each

controller, you must recable the shelf (after you have installed the additional RoCE

capable PCIe cards or I/O modules) across both sets of ports on each controller, before

hot-adding the second shelf.

Before you begin

•You must have met the system requirements.

Requirements for a hot-add

•You must have enabled the ports on the RoCE capable PCIe cards or I/O modules you installed.

Prepare non-dedicated RoCE capable ports for a hot-add

About this task

•Recabling port connections is a nondisruptive procedure when your shelf has multipath-HA connectivity.

You recable the first shelf across both sets of ports on each controller so that when you hot-add the second

shelf, both shelves have more resilient connectivity.

•You move one cable at a time to maintain connectivity to the shelf at all times during this procedure.

Steps

1. Recable the existing shelf’s connections across both sets of ports on each controller, as applicable to your

platform model.

Moving a cable does not require any wait time between unplugging the cable from one port

and plugging it into another port.

If you have an… Then…

AFF A700 or ASA A700

HA pair The substeps assume the existing shelf is cabled to RoCE

capable I/O modules in slot 3 on each controller.

If needed, you can reference cabling illustrations showing an

existing single shelf and the recabled shelf, in a two shelf

configuration.

Cable a hot-add shelf for an AFF A700 or ASA A700HA pair

a. On controller A, move the cable from slot 3 port b to slot 7 port b.

b. Repeat the same cable move on controller B.

If you have an… Then…

AFF A800 or ASA A800

HA pair The substeps assume the existing shelf is cabled to RoCE

capable PCIe cards in slot 5 on each controller.

If needed, you can reference cabling illustrations showing an

existing single shelf and the recabled shelf, in a two shelf

configuration.

Cable a hot-add shelf for an AFF A800 or ASA A800HA pair

a. On controller A, move the cable from slot 5 port 2 (e5b) to slot 3 port 2

(e3b).

b. Repeat the same cable move on controller B.

AFF A400 or ASA A400

HA pair If needed, you can reference cabling illustrations showing an

existing single shelf and the recabled shelf, in a two shelf

configuration.

Cable a hot-add shelf for an AFF A400 or ASA A400HA pair

a. On controller A, move the cable from port e0d to slot 5 Port 2 (e5b).

b. Repeat the same cable move on controller B.

2. Verify that the recabled shelf is cabled correctly.

If any cabling errors are generated, follow the corrective actions provided.

Prepare to manually assign drive ownership for a hot-add

If you are manually assigning drive ownership for the NS224 drive shelf you are hot-

adding, then you need to disable automatic drive assignment if it is enabled.

Before you begin

You must have met the system requirements.

Requirements for a hot-add

About this task

You need to manually assign drive ownership if drives in the shelf will be owned by both controller modules in

the HA pair.

Steps

1. Verify whether automatic drive assignment is enabled: storage disk option show

You can enter the command on either controller module.

If automatic drive assignment is enabled, the output shows on in the Auto Assign column (for each

controller module).

2. If automatic drive assignment is enabled, disable it: storage disk option modify -node

node_name -autoassign off

You must disable automatic drive assignment on both controller modules.

Install a drive shelf for a hot-add

Installing a new NS224 drive shelf involves installing the shelf into a rack or cabinet,

connecting the power cords (which automatically powers on the shelf), and then setting

the shelf ID.

Before you begin

•You must have met the system requirements.

Requirements for a hot-add

•You must have completed the applicable preparation procedures.

Prepare for a hot-add

Steps

1. Install the rail mount kit that came with your shelf by using the installation flyer that came in the kit box.

Do not flange-mount the shelf.

2. Install and secure the shelf onto the support brackets and rack or cabinet by using the installation flyer.

A fully loaded NS224 shelf can weigh up to 66.78 lbs (30.29 kg) and requires two people to

lift or use of a hydraulic lift. Avoid removing shelf components (from the front or rear of the

shelf) to reduce the shelf weight, because shelf weight will become unbalanced.

3. Connect the power cords to the shelf, secure them in with the power cord retainer, and then connect the

power cords to different power sources for resiliency.

A shelf powers up when connected to a power source; it does not have power switches. When functioning

correctly, a power supply’s bicolored LED illuminates green.

4. Set the shelf ID to a number that is unique within the HA pair:

More detailed instructions are available:

Change a shelf ID - NS224 shelves

a. Remove the left end cap and locate the small hole to the right of the LEDs.

b. Insert the end of a paper clip or similar tool into the small hole to reach the shelf ID button.

c. Press and hold the button (for up to 15 seconds) until the first number on the digital display blinks, and

then release the button.

If the ID takes longer than 15 seconds to blink, press and hold the button again, making

sure to press it in all the way.

d. Press and release the button to advance the number until you reach the desired number from 0 to 9.

e. Repeat substeps 4c and 4d to set the second number of the shelf ID.

It can take up to three seconds (instead of 15 seconds) for the number to blink.

f. Press and hold the button until the second number stops blinking.

After about five seconds, both numbers start blinking and the amber LED on the ODP illuminates.

g. Power-cycle the shelf to make the shelf ID take effect.

You must unplug both power cords from the shelf, wait 10 seconds, and then plug them back in.

When power is restored to the power supplies, their bicolored LEDs illuminate green.

Cable a drive shelf for a hot-add

You cable each NS224 drive shelf you are hot-adding so that each shelf has two

connections to each controller module in the HA pair. Depending on the number of

shelves you are hot-adding and your platform model, you use RoCE capable ports on

board the controllers, on RoCE capable PCIe cards, a combination of both, or on RoCE

capable I/O modules.

Considerations when cabling for a hot-add

Familiarizing yourself with proper cable connector orientation, and the location and

labeling of ports on the NS224 NSM drive shelf modules can be helpful before cabling

your hot-added shelf.

•Cables are inserted with the connector pull-tab facing up.

When a cable is inserted correctly, it clicks into place.

After you connect both ends of the cable, the shelf and controller port LNK (green) LEDs illuminate. If a

port LNK LED does not illuminate, reseat the cable.

•You can use the following illustration to help you physically identify the shelf NSM ports, e0a and e0b:
