Replace the boot media - NS224 shelves

When the boot media fails on an NS224 drive shelf in an HA pair that is running ONTAP

9.7 or later, or the shelf is running NVMe shelf module (NSM) firmware version 1.1x or

later, you can replace the boot media. Replacing the boot media can be done

nondisruptively, while the drive shelf is powered on, and I/O is in progress.

Before you begin

•Your HA pair must already be running ONTAP 9.7 or later, which has the minimum supported version of

NSM firmware, or your HA pair must already been running a version of ONTAP 9.6 with NSM firmware

version 1.1x or later.

You can enter the storage shelf show -module command at the console of either controller to verify

the version of NSM firmware on your shelf.

If your shelf is not running NSM firmware version 1.1x or later, you cannot replace the boot

media, you must replace the NSM module.

Replace an NSM module - NS224 shelves

•You need a Phillips #1 screwdriver.

The screw used to secure the boot media to the board requires a Phillips #1 screwdriver; using a different

type of screwdriver could strip the screw.

•The shelf’s partner NSM module must be up and running, and be cabled correctly so that your shelf

maintains connectivity when you remove the NSM module with the failed FRU (target NSM module).

NetApp Downloads: Config Advisor

•All other components in the system must be functioning properly.

About this task

•After the boot media is replaced, the boot image from the shelf’s partner NSM module is automatically

copied to the replacement boot media.

This can take up to five minutes.

•Allow at least 70 seconds between removal and installation of the NVMe shelf module (NSM).

This allows enough time for ONTAP to process the NSM removal event.

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

drive firmware on your system before replacing FRU components.

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

•If needed, you can turn on the shelf’s location (blue) LEDs to aid in physically locating the affected shelf:

storage shelf location-led modify -shelf-name shelf_name -led-status on

If you do not know the shelf_name of the affected shelf, run the storage shelf show command.

A shelf has three location LEDs: one on the operator display panel and one on each NSM module.

Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command,

but using the off option.

•After replacing the boot media, you can return the failed part to NetApp as described in the RMA

instructions shipped with the kit.

If you need the RMA number or additional help with the replacement procedure, contact technical support

at NetApp Support, 888-463-8277 (North America), 00-800-44-638277 (Europe), or +800-800-80-800

(Asia/Pacific).

•You can use the following video or the written steps to replace the boot media.

Replacing the boot media in an NS224 drive shelf

Steps

1. Properly ground yourself.

2. Disconnect the cabling from the NSM module that contains the FRU that you are replacing:

a. Disconnect the power cord from the power supply by opening the power cord retainer, and then unplug

the power cord from the power supply.

Power supplies do not have a power switch.

b. Disconnect the storage cabling from the NSM module ports.

Make a note of the NSM module ports that each cable is connected to. You reconnect the cables to the

same ports when you reinsert the NSM module, later in this procedure.

3. Remove the NSM module from the shelf:

a. Loop your index fingers through the finger holes of the latching mechanisms on either side of the NSM

module.

If you are removing the bottom NSM module, and if the bottom rail is obstructing access

to the latching mechanisms, place your index fingers through the finger holes from the

inside (by crossing your arms).

b. With your thumbs, press down and hold the orange tabs on top of the latching mechanisms.

The latching mechanisms raise, clearing the latching pins on the shelf.

c. Gently pull until the NSM module is about one third of the way out of the shelf, grasp the NSM module

sides with both hands to support its weight, and then place it on a flat stable surface.

When you begin pulling, the latching mechanism arms extend from the NSM module and lock in their

fully extended position.

4. Loosen the NSM module cover thumb screw and open the cover.

5. Physically locate the failed boot media.

The boot media is located along the shelf chassis wall opposite from the power supply. The boot media

attention (amber) LED, located on the board next to the boot media slot, is illuminated.

The LED remains illuminated for 10 minutes after you remove the NSM module from the

shelf.

6. Replace the boot media:

a. Using the Phillips #1 screwdriver, carefully remove the screw securing the bottom (notched) end of the

boot media to the board.

b. Remove the boot media by rotating the notched end up slightly and then gently pulling it towards you

until it releases from the socket.

You can hold the boot media by placing your thumb and forefinger on the side edges, at the notched

end.

c. Unpack the boot media from the antistatic bag.

d. Insert the replacement boot media by pushing it gently into the socket until it is seated squarely and

completely in the socket.

You can hold the boot media by placing your thumb and forefinger on the side edges, at the notched

end. Make sure that the side with the heat sink is facing up.

When correctly seated, and when you let go of the boot media, the notched end of the boot media is

angled up, away from the board, because it is not yet secured with the screw.

e. Gently hold down the notched end of the boot media as you insert and tighten the screw with the

screwdriver to secure the boot media in place.

Tighten the screw just enough to hold the boot media securely in place, but do not

overtighten.

7. Close the NSM module cover, and then tighten the thumb screw.

8. Reinsert the NSM module into the shelf:

a. Make sure that the latching mechanism arms are locked in the fully extended position.

b. Using both hands, gently slide the NSM module into the shelf until the weight of the NSM module is

fully supported by the shelf.

c. Push the NSM module into the shelf until it stops (about half an inch from the back of the shelf).

You can place your thumbs on the orange tabs on the front of each finger loop (of the latching

mechanism arms) to push in the NSM module.

d. Loop your index fingers through the finger holes of the latching mechanisms on either side of the NSM

module.

If you are inserting the bottom NSM module, and if the bottom rail is obstructing access

to the latching mechanisms, place your index fingers through the finger holes from the

inside (by crossing your arms).

e. With your thumbs, press down and hold the orange tabs on top of the latching mechanisms.

f. Gently push forward to get the latches over the stop.

g. Release your thumbs from the tops of the latching mechanisms, and then continue pushing until the

latching mechanisms snap into place.

The NSM module should be fully inserted into the shelf and flush with the edges of the shelf.

9. Reconnect the cabling to the NSM module:

a. Reconnect the storage cabling to the same two NSM module ports.

Cables are inserted with the connector pull-tab facing up. When a cable is inserted correctly, it clicks

into place.

b. Reconnect the power cord to the power supply, and then secure the power cord with the power cord

retainer.

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

Additionally, both NSM module port LNK (green) LEDs illuminate. If a LNK LED does not illuminate,

reseat the cable.

10. Verify that the attention (amber) LEDs on the NSM module containing the failed boot media and the shelf

operator display panel are no longer illuminated.

It can take between 5 to 10 minutes for the attention LEDs to turn off. This is the amount of time it takes the

NSM module to reboot and the boot media image copy to complete.

If the fault LEDs remain on, the boot media might not be seated correctly or there might be another issue

and you should contact technical support for assistance.

11. Verify that the NSM module is cabled correctly, by running Active IQ Config Advisor.

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

When you begin pulling, the latching mechanism arms extend from the NSM module and lock in their

fully extended position.

4. Loosen the NSM module cover thumb screw and open the cover.

The FRU label on the NSM module cover shows the location of the four DIMMs, two on either side of the

heat sink, in the center of the NSM module.

5. Physically identify the faulty DIMM.

When a DIMM is faulty, the system logs a warning message to the system console indicating which DIMM

is faulty. Additionally, the DIMM attention (amber) LED, located on the board next to the DIMM slot,

illuminates.

The LED for the faulty DIMM remains illuminated for 10 minutes after you remove the NSM

module from the shelf.

6. Replace the faulty DIMM:

a. Note the orientation of the DIMM in the slot so that you can insert the replacement DIMM using the

same orientation.

b. Eject the DIMM from its slot by slowly pushing apart the ejector tabs at both ends of the DIMM slot, and

then lift the DIMM out of the slot.

Carefully hold the DIMM by the corners or edges to avoid pressure on the DIMM circuit

board components.

The ejector tabs remain in the open position.

c. Remove the replacement DIMM from its antistatic shipping bag.

d. Hold the DIMM by the corners, and then insert the DIMM squarely into a slot.

The notch on the bottom of the DIMM, among the pins, should line up with the tab in the slot.

When inserted correctly, the DIMM should go in easily but fit tightly in the slot. If not, reinsert the DIMM.

e. Push down carefully, but firmly, on the top edge of the DIMM until the ejector tabs snap into place over

the notches at both ends of the DIMM.

7. Close the NSM module cover, and then tighten the thumb screw.

8. Reinsert the NSM module into the shelf:

a. Make sure that the latching mechanism arms are locked in the fully extended position.

b. Using both hands, gently slide the NSM module into the shelf until the weight of the NSM module is

fully supported by the shelf.

c. Push the NSM module into the shelf until it stops (about half an inch from the back of the shelf).

reseat the cable.

10. Verify that the attention (amber) LEDs on the NSM module containing the failed DIMM and the shelf

operator display panel are no longer illuminated.

The NSM module attention LEDs turn off after the NSM module reboots and no longer detects a DIMM

issue. This can take three to five minutes.

11. Verify that the NSM module is cabled correctly, by running Active IQ Config Advisor.

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

Hot-swap a drive - NS224 shelves

You can replace a failed drive nondisruptively in an NS224 drive shelf that is powered on,

and while I/O is in progress.

Before you begin

•The drive that you are installing must be supported by the NS224 shelf.

NetApp Hardware Universe

•If SED authentication is enabled, you must use the SED replacement instructions in the ONTAP

documentation.

Instructions in the ONTAP documentation describe additional steps you must perform before and after

replacing an SED.

NetApp encryption overview with the CLI

•All other components in the system must be functioning properly; if not, contact technical support.

•Verify that the drive you are removing is failed.

You can verify that the drive is failed by running the storage disk show -broken command. The

failed drive appears in the list of failed drives. If it does not, you should wait, and then run the command

again.

Depending on the drive type and capacity, it can take up to several hours for the drive to

appear in the list of failed drives.

About this task

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

installed before hot-swapping a drive.

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.

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

drive firmware on your system before replacing FRU components.

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

•Drive firmware is automatically updated (nondisruptively) on new drives that have non current firmware

versions.

Drive firmware checks occur every two minutes.

•If needed, you can turn on the shelf’s location (blue) LEDs to aid in physically locating the affected shelf:

storage shelf location-led modify -shelf-name shelf_name -led-status on

If you do not know the shelf_name of the affected shelf, run the storage shelf show command.
