Hot-swapping a disk drive in a DS224C or DS212C disk shelf

You can hot-swap a failed disk drive in a DS224C or DS212C disk shelf—nondisruptively replace a disk drive in a system that is powered on and serving data (I/O is in progress). When a disk drive fails, the system logs a warning message to the system console indicating which disk drive has failed. In addition, the attention (amber) LED on the operator display panel and the attention (amber) LED on the failed disk drive illuminate.

Before you begin

• The disk drive that you are installing must be supported by the DS224C or DS212C disk shelf.

NetApp Hardware Universe

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

• The disk drive you are removing must be failed. You can verify the disk drive is failed by running the storage disk show -broken command.

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

Note: It can take up to several hours for the disk drive to appear in the list of failed disk drives.

• If you are replacing a self-encrypting disk (SED), you must follow the instructions for replacing an SED in the

The instructions describe additional steps you must perform before and after replacing an SED.

Disks and Aggregates Power Guide

ONTAP 9 Disks and Aggregates Power Guide

About this task

• You should take steps to avoid electrostatic discharge (ESD):

◦ Keep the disk drive in the ESD bag until you are ready to install it. ◦ Open the ESD bag by hand or cut the top off with a pair of scissors.

Attention: Do not insert a metal tool or knife into the ESD bag.

◦ Always wear an ESD wrist strap grounded to an unpainted surface on your storage enclosure

chassis. If a wrist strap is unavailable, touch an unpainted surface on your storage enclosure chassis

before handling the disk drive.

• You should take steps to handle disk drives carefully: ◦ Always use two hands when removing, installing, or carrying a disk drive to support its

weight.

Attention: Do not place hands on the disk drive boards exposed on the underside of the disk

drive carrier.

◦ You should place disk drives on cushioned surfaces, and never stack disk drives on top of each

other.

◦ You should be careful not to bump disk drives against other surfaces.

• Disk drives should be kept away from magnetic devices.

Hot-swapping a disk drive in a DS224C or DS212C disk shelf |

Attention: Magnetic fields can destroy all data on the disk drive and cause irreparable damage

to the disk drive circuitry.

• Best practice is to have the current version of the Disk Qualification Package (DQP) installed before hot-swapping a disk drive.

Having the current version of the DQP installed allows your system to recognize and utilize newly qualified disk drives; therefore, avoiding system event messages about having non-current disk drive information. You also avoid the possible prevention of disk partitioning because disk drives are not recognized. The DQP also notifies you of non-current disk drive firmware.

NetApp Downloads: Disk Qualification Package

• Best practice is to have the current versions of disk shelf (IOM) firmware and disk drive firmware on your system before adding new disk shelves, shelf FRU components, or SAS cables.

Current versions of firmware can be found on the NetApp Support Site.

NetApp Downloads: Disk Shelf Firmware NetApp Downloads: Disk Drive and Firmware

• Disk drive firmware is automatically updated (nondisruptively) on new disk drives with non current firmware versions.

Note: Disk drive firmware checks occur every two minutes.

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

storage shelf location-led modify -node node_name -shelf-name shelf_name

-led-status on

A disk shelf has three location (blue) LEDs: one on the operator display panel and one on each IOM12 module. Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command, but using the off option.

• If needed, you can refer to the Monitoring disk shelf LEDs section for information about the meaning and location of disk shelf LEDs on the operator display panel and FRU components.

Steps

1. If you want to manually assign disk ownership for the replacement disk drive, you need to disable

disk ownership automatic assignment if it is enabled; otherwise, go to the next step.

Note: You need to manually assign disk ownership if disk drives in the stack are owned by both

controllers in an HA pair.

Note: You manually assign disk ownership and then reenable disk ownership automatic

assignment later in this procedure.

a. Verify if disk ownership automatic assignment is enabled:

storage disk option show

If you have an HA pair, you can enter the command at the console of either controller. If disk ownership automatic assignment is enabled, the output shows “on” (for each

controller) in the “Auto Assign” column.

b. If disk ownership automatic assignment is enabled, you need to disable it:

storage disk option modify -node node_name -autoassign off

You need to disable disk ownership automatic assignment on both controllers in an HA pair.

2. Properly ground yourself.

3. Unpack the new disk drive, and set it on a level surface near the disk shelf.

| Service Guide for DS460C, DS224C and DS212C Disk Shelves

Save all packaging materials for use when returning the failed disk drive.

Note: NetApp requires that all returned disk drives be in a ESD-rated bag.

4. Physically identify the failed disk drive from the system console warning message and the

illuminated attention (amber) LED on the disk drive.

Note: The activity (green) LED on a failed disk drive can be illuminated (solid), which

indicates the disk drive has power, but should not be blinking, which indicates I/O activity. A failed disk drive has no I/O activity.

5. Press the release button on the disk drive face, and then pull the cam handle to its fully open

position to release the disk drive from the mid plane. When you press the release button, the cam handle on the disk drive springs open partially.

Note: Disk drives in a DS212C disk shelf are arranged horizontally with the release button

located on the left of the disk drive face. Disk drives in a DS224C disk shelf are arranged vertically with the release button located at the top of the disk drive face.

The following illustrations show disk drives in a DS212C disk shelf:

6.0TB

6. Slide out the disk drive slightly to allow the disk to safely spin down, and then remove the disk

drive from the disk shelf. A disk can take up to one minute to safely spin down.

Note: When handling a disk drive, always use two hands to support its weight.

7. Using two hands, with the cam handle in the open position, insert the replacement disk drive into

the disk shelf, firmly pushing until the disk drive stops.

Note: Wait a minimum of 10 seconds before inserting a new disk drive. This allows the system

to recognize that a disk drive was removed.

Note: Do not place hands on the disk drive boards that are exposed on the underside of the disk

carrier.

8. Close the cam handle so that the disk drive is fully seated into the mid plane and the handle clicks

into place. Be sure to close the cam handle slowly so that it aligns correctly with the face of the disk drive.

Hot-swapping a disk drive in a DS224C or DS212C disk shelf | 7

9. If you are replacing another disk drive, repeat Steps 3 through 8.

10. Verify the disk drive's activity (green) LED is illuminated.

When the disk drive's activity LED is solid green, it means the disk drive has power. When the disk drive's activity LED is blinking, it means the disk drive has power and I/O is in progress.

11. If you disabled disk ownership automatic assignment in Step 1, manually assign disk ownership,

and then reenable disk ownership automatic assignment if needed:

a. Display all unowned disks:

storage disk show -container-type unassigned

b. Assign each disk:

storage disk assign -disk disk_name -owner owner_name

You can use the wildcard character to assign more than one disk at once.

c. Reenable disk ownership automatic assignment if needed:

storage disk option modify -node node_name -autoassign on

You need to reenable disk ownership automatic assignment on both controllers in an HA pair.

12. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.

b. Open both release levers by pulling the latches toward you. c. While holding both release levers, pull the drive drawer toward you.

d. Remove the drive drawer from the drive shelf.

Installing a drive drawer

Installing a drive drawer into a drive shelf entails sliding the drawer into the empty slot, installing the drives, and replacing the front bezel.

Before you begin

• You know where to install each drive.

• You have obtained the following items:

◦ Replacement drive drawer ◦ Flashlight

Steps

1. From the front of the drive shelf, shine a flashlight into the empty drawer slot, and locate the lock-

out tumbler for that slot. The lock-out tumbler assembly is a safety feature that prevents you from being able to open more

than one drive drawer at one time.

Replacing a drive drawer in a DS460C disk shelf |

1 Lock-out tumbler 2 Drawer guide

2. Position the replacement drive drawer in front of the empty slot and slightly to the right of center.

Positioning the drawer slightly to the right of center helps to ensure that the lock-out tumbler and the drawer guide are correctly engaged.

3. Slide the drive drawer into the slot, and ensure that the drawer guide slides under the lock-out

tumbler.

Attention: Risk of equipment damage – Damage occurs if the drawer guide does not slide

under the lock-out tumbler.

4. Carefully push the drive drawer all the way in until the latch fully engages.

Attention: Risk of equipment damage — Stop pushing the drive drawer if you feel excessive

resistance or binding. Use the release levers at the front of the drawer to slide the drawer back out. Then, reinsert the drawer into the slot, and ensure that it slides in and out freely.

5. Follow these steps to reinstall the drives in the drive drawer:

a. Unlatch the drive drawer by pulling out on both levers at the front of the drawer. b. Using the extended levers, carefully pull the drive drawer out until it stops. Do not completely

remove the drive drawer from the drive shelf.

c. Determine which drive to install in each slot by using the notes you made when removing the

drives.

Attention: Possible loss of data access – You must install each drive in its original location

in the drive drawer.

| Service Guide for DS460C, DS224C and DS212C Disk Shelves

d. Raise the handle on the drive to vertical.

e. Align the two raised buttons on each side of the drive with the notches on the drawer.

The figure shows the right side view of a drive, showing the location of the raised buttons.

g. Repeat these substeps to reinstall all of the drives. Slide the drawer back into the drive shelf by pushing it from the center and closing both levers.

Attention: Risk of equipment malfunction – Make sure to completely close the drive drawer

by pushing both levers. You must completely close the drive drawer to allow proper airflow and prevent overheating.

7. Attach the bezel to the front of the drive shelf.

Attaching the cable chains

The final step in installing a drive drawer is attaching the left and right cable chains to the drive shelf. When attaching a cable chain, reverse the order you used when disconnecting the cable chain. You must insert the chain's horizontal connector into the horizontal bracket in the enclosure before inserting the chain's vertical connector into the vertical bracket in the enclosure.

Before you begin

• You have replaced the drive drawer and all of the drives.

• You have two replacement cable chains, marked as LEFT and RIGHT (on the horizontal connector next to the drive drawer).

d. Slide the vertical connector on the right cable chain into the vertical bracket.

e. After you reconnect both ends of the cable chain, carefully pull on the cable chain to verify

that both connectors are latched.

Attention: Risk of equipment malfunction — If the connectors are not latched, the cable

chain might come loose during drawer operation.

Reinstall the right fan module.

Reapply power:

a. Turn on both power switches on the drive shelf. b. Confirm that both fans come on and that the amber LED on the back of the fans is off.

Hot-swapping or replacing an IOM12 module

Your system configuration determines whether you can perform a nondisruptive IOM12 module hotswap or a disruptive IOM12 module replacement when an IOM12 module fails. When an IOM12 module fails, the system logs a warning message to the system console indicating which IOM12 module has failed. In addition, the attention (amber) LED on the operator display panel and the attention (amber) LED on the failed IOM12 module illuminate.

Before you begin

All other components in the system—including the other IOM12 module—must be functioning properly.

About this task

• For multipathed (multipath HA or multipath) and quad-pathed (quad-path HA or quad-path) configurations, you can hot-swap an IOM12 module (nondisruptively replace an IOM12 module in a system that is powered on and serving data—I/O is in progress).

• For FAS2600 series single-path HA configurations, you must perform a takeover and giveback operation to replace an IOM12 module in a system that is powered on and serving data—I/O is in progress.

• For FAS2600 series single-path configurations, you must halt your system to replace an IOM12 module.

Attention: If you attempt to hot-swap an IOM12 module on a disk shelf with a single-path

connection, you will lose all access to the disk drives on the disk shelf as well as any disk shelves beneath. You could also bring down your entire system.

• Best practice is to have the current versions of disk shelf (IOM) firmware and disk drive firmware on your system before adding new disk shelves, shelf FRU components, or SAS cables.

Current versions of firmware can be found on the NetApp Support Site.

NetApp Downloads: Disk Shelf Firmware NetApp Downloads: Disk Drive and Firmware

• Disk shelf (IOM) firmware is automatically updated (nondisruptively) on a new IOM12 module with a non current firmware version.

IOM firmware checks occur every ten minutes. An IOM firmware update can take up to 30 minutes.

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

storage shelf location-led modify -node node_name -shelf-name shelf_name

-led-status on

• If needed, you can refer to the Monitoring disk shelf LEDs section for information about the meaning and location of disk shelf LEDs on the operator display panel and FRU components.

Steps

1. Properly ground yourself.

Hot-swapping or replacing an IOM12 module |

2. Unpack the new IOM12 module, and set it on a level surface near the disk shelf.

Save all packaging materials for use when returning the failed IOM12 module.

3. Physically identify the failed IOM12 module from the system console warning message and the

illuminated attention (amber) LED on the failed IOM12 module.

4. Perform one of the following actions based on the type of configuration you have: If you have a... Then...

Multipath HA, multipath,

a. Determine the target node (the node the failed IOM12 module

belongs to). IOM A belongs to Controller 1. IOM B belongs to Controller 2.

b. Take over the target node:

storage failover takeover -bynode partner HA node

FAS2600 series singlepath configuration

a. Shut down the system from the system console:

halt

b. Verify that your system halted by checking the storage system

console.

5. Disconnect the cabling from the IOM12 module that you are removing.

Make note of the IOM12 module ports each cable is connected to.

6. Press the orange latch on the IOM12 module cam handle until it releases, and then open the cam

handle fully to release the IOM12 module from the mid plane.

| Service Guide for DS460C, DS224C and DS212C Disk Shelves

Use the cam handle to slide the IOM12 module out of the disk shelf.

If you have a DS224C or DS212C disk shelf, as you remove the power supply, a plastic flap swings into place to block the empty bay, helping to maintain air flow and cooling.

Note: When handling an IOM12 module, always use two hands to support its weight.

Wait at least 70 seconds after removing the IOM12 module before you install the new IOM12

module. Waiting at least 70 seconds enables the driver to register the shelf ID correctly.

9. Using two hands, with the cam handle of the new IOM12 module in the open position, support

and align the edges of the new IOM12 module with the opening in the disk shelf, and then firmly push the new IOM12 module until it meets the mid plane.

Attention: Do not use excessive force when sliding the IOM12 module into the disk shelf; you

might damage the connectors.

10. Close the cam handle so that the latch clicks into the locked position and the IOM12 module is

fully seated.

11. Reconnect the cabling.

The SAS cable connectors are keyed; when oriented correctly into an IOM port, the connector clicks into place and the IOM port LNK LED illuminates green. You insert a SAS cable connector into an IOM port with the pull tab oriented down (on the underside of the connector).

12. Perform one of the following actions based on the type of configuration you have: If you have a...

Multipath HA, multipath,

Then...

Go to the next step. quad-path HA, or quad-path configuration

13. Verify that the IOM12 module port links have been established.

For each module port that you cabled, the LNK (green) LED illuminates when one or more of the four SAS lanes have established a link (with either an adapter or another disk shelf).

14. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.

Reboot your system.

Hot-removing disk shelves with IOM12 modules

You can hot-remove a disk shelf with IOM12 modules—nondisruptively remove a disk shelf from a system that is powered on and serving data (I/O is in progress)—when you need to move or replace the disk shelf. You can hot-remove one or more disk shelves from anywhere within a stack of disk shelves or remove a stack of disk shelves.

Before you begin

• Your system must be a multipath HA, multipath, quad-path HA, or quad-path configuration. For FAS2600 series, the external storage must be cabled as multipath HA or multipath.

Note: For a FAS2600 series single-controller system that has the external storage cabled with

multipath connectivity, the system is a mixed-path configuration because the internal storage uses single-path connectivity.

• HA pair configurations cannot be in a takeover state.

• You must have removed all aggregates from the disk drives—the disk drives must be spares— in the disk shelves you are removing.

Attention: If you attempt this procedure with aggregates on the disk shelf you are removing,

you could fail the system with a multidisk panic.

You can use the storage aggregate offline -aggregate aggregate_name command.

• If you are removing one or more disk shelves from within a stack, you must have factored the distance to bypass the disk shelves you are removing; therefore, if the current cables are not long enough, you need to have longer cables available.

About this task

• Best practice is to remove disk drive ownership after you remove the aggregates from the disk drives in the disk shelves you are removing.

Removing ownership information from a spare disk drive allows the disk drive to be properly integrated into another node (as needed).

The procedure for removing ownership from a disk can be found in the

Power Guide

Note: The procedure for removing ownership from disk drives requires you to disable disk

ownership automatic assignment. You reenable disk ownership automatic assignment at the end of this procedure.

Disks and Aggregates

ONTAP 9 Disks and Aggregates Power Guide

• For a clustered ONTAP system that is greater than two-nodes, best practice is to have reassigned epsilon to an HA pair other than the one that is undergoing planned maintenance.

Reassigning epsilon minimizes the risk of unforeseen errors impacting all nodes in a clustered ONTAP system. Information about the role of quorum and epsilon, and the procedure for reassigning epsilon to another node in a cluster can be found in the

Reference

System Administration

Find a System Administration Guide for your version of ONTAP 9

• If you are hot-removing a disk shelf from a stack (but keeping the stack), you recable and verify one path at a time (path A then path B) to bypass the disk shelf you are removing so that you always maintain single-path connectivity from the controllers to the stack.

Hot-removing disk shelves with IOM12 modules |

Attention: If you do not maintain single-path connectivity from the controllers to the stack

when recabling the stack to bypass the disk shelf you are removing, you could fail the system with a multidisk panic.

Steps

1. Verify that your system configuration is Multi-Path HA, Multi-Path, Quad-path HA, or

Quad-path:

sysconfig

You run this command from the nodeshell of either controller. It might take up to a minute for the system to complete discovery.

The configuration is listed in the System Storage Configuration field.

Note: For FAS2600 series systems with external storage, the output is displayed as Mixed-

Path HA for an HA pair, or Mixed-Path for a single-controller configuration because the

internal storage is cabled differently than the external storage. For an HA pair, the internal storage is cabled as single-path HA and the external storage is cabled as multipath HA. For a single-controller configuration, the internal storage is cabled as single-path and the external storage is cabled as multipath.

2. Verify that the disk drives in the disk shelves you are removing have no aggregates (are spares)

and ownership is removed, by completing the following substeps:

a. Enter the following command from the clustershell of either controller:

storage disk show -shelf shelf_number

b. Check the output to verify there are no aggregates on the disk drives in the disk shelves you

are removing. Disk drives with no aggregates have a dash in the Container Name column.

c. Check the output to verify that ownership is removed from the disk drives on the disk shelves

you are removing. Disk drives with no ownership have unassigned in the Container Type column.

Note: If you have failed disk drives in the shelf you are removing, they have broken in the

Container Type column. (Failed disk drive do not have ownership.)

Example

The following output shows disk drives on the disk shelf being removed (disk shelf 3) are in a correct state for removing the disk shelf. Aggregates have been removed on all of the disk drives in disk shelf 3; therefore, a dash appears in the Container Name column for each disk drive. Ownership has been removed on two disk drives; therefore, unassigned appears in the

Container Type column. And two disk drives are failed; therefore, broken appears in the Container Type column:

cluster::> storage disk show -shelf 3

Usable Disk Container Container Disk Size Shelf Bay Type Type Name Owner

-------- -------- ----- --- ------ ----------- ---------- --------...

1.3.4 - 3 4 SAS unassigned - -

1.3.5 - 3 5 SAS unassigned - -

1.3.6 - 3 6 SAS broken - -

1.3.7 - 3 7 SAS broken - ...

| Service Guide for DS460C, DS224C and DS212C Disk Shelves

3. Physically locate the disk shelves you are removing.

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

storage shelf location-led modify -node node_name -shelf-name shelf_name

-led-status on

Note: A disk shelf has three location (blue) LEDs: one on the operator display panel and one

on each IOM12 module. Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command, but using the off option.

If you are removing an entire stack of disk shelves, complete the following substeps; otherwise,

go to the next step:

a. Remove all SAS cables on path A (IOM A) and path B (IOM B).

This includes controller-to-shelf cables and shelf-to-shelf cables for all disk shelves in the stack you are removing.

b. Go to step

If you are removing one or more disk shelves from a stack (but keeping the stack), recable the

on page 44.

path A (IOM A) stack connections to bypass the disk shelves you are removing by completing the applicable set of substeps:

If you are removing more than one disk shelf in the stack, complete the applicable set of substeps one disk shelf at a time.

Note: Wait at least 10 seconds before connecting the port. The SAS cable connectors are

keyed; when oriented correctly into a SAS port, the connector clicks into place and the disk shelf SAS port LNK LED illuminates green. For disk shelves, you insert a SAS cable connector with the pull tab oriented down (on the underside of the connector).

If you are removing... Then...

A disk shelf from either end (logical first or last disk shelf) of a stack

A disk shelf from the middle of the stack

A disk shelf in the middle of a stack is only connected to other disk shelves—not to any controllers.

a. Remove any shelf-to-shelf cabling from IOM A ports on the disk

shelf you are removing and put them aside.

b. Unplug any controller-to-stack cabling connected to IOM A ports on

the disk shelf you are removing and plug them into the same IOM A ports on the next disk shelf in the stack.

The “next” disk shelf can be above or below the disk shelf you are removing depending on which end of the stack you are removing the disk shelf from.

a. Remove any shelf-to-shelf cabling from IOM A ports 1 and 2 or from

ports 3 and 4 on the disk shelf you are removing and IOM A of the next disk shelf, and then put them aside.

b. Unplug the remaining shelf-to-shelf cabling connected to IOM A

ports on the disk shelf you are removing and plug them into the same IOM A ports on the next disk shelf in the stack.

Example

You can refer to the following cabling examples when removing a disk shelf from an end of a stack or the middle of a stack. Note the following about the cabling examples:

The “next” disk shelf can be above or below the disk shelf you are removing depending on which IOM A ports (1 and 2 or 3 and 4) you removed the cabling from.

Hot-removing disk shelves with IOM12 modules |

• The IOM12 modules are arranged side-by-side as in a DS224C or DS212C disk shelf; if you

have a DS460C, the IOM12 modules are arranged one above the other.

• The stack in each example is cabled with standard shelf-to-shelf cabling, which is used in

stacks cabled with multipath HA or multipath connectivity. You can infer the recabling if your stack is cabled with quad-path HA or quad-path

connectivity, which uses double-wide shelf-to-shelf cabling.

• The cabling examples demonstrate recabling one of the paths: path A (IOM A).

You repeat the recabling for path B (IOM B).

• The cabling example for removing a disk shelf from the end of a stack demonstrates removing

the logical last disk shelf in a stack that is cabled with multipath HA connectivity. You can infer the recabling if you are removing the logical first disk shelf in a stack or if your

stack has multipath connectivity.

6. Verify that you bypassed the disk shelves you are removing and reestablished the path A (IOM A)

stack connections correctly:

storage disk show -port

For HA pair configurations, you run this command from the clustershell of either controller. It might take up to a minute for the system to complete discovery.

Example

The first two lines of output show disk drives with connectivity through both path A and path B. The last two lines of output show disk drives with connectivity through a single-path, path B.

| Service Guide for DS460C, DS224C and DS212C Disk Shelves

cluster::> storage show disk -port

PRIMARY PORT SECONDARY PORT TYPE SHELF BAY

-------- ---- --------- ---- ---- ----- ---

1.20.1 A node1:6a.20.1 B SAS 20 1

1.21.0 B - - SAS 21 0

1.21.1 B - - SAS 21 1 ...

7. The next step depends on the storage disk show -port command output:

If the output shows... Then...

All disk drives in the stack are connected through path A and path B except for the ones in the disk shelves you disconnected, which are only connected through path B

Anything other than the above

Go to the next step. You successfully bypassed the disk shelves you are removing and

reestablished path A on the remaining disk drives in the stack.

Repeat Step 5 and Step 6. You must correct the cabling.

8. Complete the following substeps for the disk shelves (in the stack) you are removing:

a. Repeat Step 5 through Step 7 for path B.

Note: When you repeat Step 7 and if you have recabled the stack correctly, you should only

see all remaining disk drives connected through path A and path B.

b. Repeat Step 1 to confirm that your system configuration is the same as before you removed

one or more disk shelves from a stack.

c. Go to the next step.

9. If when you removed ownership from the disk drives (as part of the preparation for this

procedure), you disabled disk ownership automatic assignment, reenable it by entering the following command; otherwise, go to the next step:

storage disk option modify -autoassign on

For HA pair configurations, you run the command from the clustershell of both controllers.

10. Power off the disk shelves you disconnected and unplug the power cords from the disk shelves.

11. Remove the disk shelves from the rack or cabinet.

To make disk shelves lighter and easier to maneuver, remove the power supplies and IOM12 modules. Avoid removing the disk drives if possible, because excessive handling can lead to internal damage.

Caution: It is recommended that you use a mechanical hoist or lift if you are moving a fully

populated DS460C disk shelf, which can weigh 249 lb (113 kg).

Monitoring disk shelf LEDs

You can monitor the health of your disk shelf by understanding the location and status conditions of the LEDs on your disk shelf components.

Operator display panel LEDs

The LEDs on the disk shelf front operator display panel indicate whether your disk shelf is functioning normally or there are problems with the hardware.

The following table describes the three LEDs on the operator display panel used in DS460C, DS224C, and DS212C disk shelves:
