Requirements for E5700 drive replacement
Before you replace a drive, review the requirements and considerations.
Shelf types
You can replace a drive in a 24-drive shelf, in a 60-drive shelf, or in a drive drawer.
24-drive shelves
The figures show how the drives are numbered in each type of shelf (the shelf’s front bezel or end caps have
been removed).
Drive numbering in an E5724 controller shelf or DE224C drive shelf
Your E5724 storage array might include one or more SAS-2 legacy expansion drive trays,
including the DE5600 24-drive tray or the DE6600 60-drive tray. For instructions for replacing a
drive in one of these drive trays, see Replacing a Drive in E2660, E2760, E5460, E5560, or
E5660 Drive Trays and Replacing a Drive in E2600, E2700, E5400, E5500, and E5600 12-Drive
or 24-Drive Trays.
60-drive shelves
Both the E5760 controller shelf and the DE460C drive shelf consist of five drive drawers that each contain 12
drive slots. Drive drawer 1 is at the top, and drive drawer 5 is at the bottom.
1

For both an E5760 controller shelf drawer and a DE460C drive shelf drawer, drives are numbered from 0 to 11
in each drive drawer within the shelf.
Your E5760 storage array might include one or more SAS-2 legacy expansion drive trays,
including the DE1600 12-drive tray, the DE5600 24-drive tray, or the DE6600 60-drive tray. For
instructions for replacing a drive in one of these drive trays, see Replacing a Drive in E2660,
E2760, E5460, E5560, or E5660 Drive Trays and Replacing a Drive in E2600, E2700, E5400,
E5500, and E5600 12-Drive or 24-Drive Trays.
Drive drawer
You can replace a drive drawer in a E5760 controller shelf and a DE460C drive shelf. Each of these 60-drive
shelves has five drive drawers.
2

Each of the five drawers can hold up to 12 drives.
Requirements for handling drives
The drives in your storage array are fragile. Improper drive handling is a leading cause of drive
failure.
Follow these rules to avoid damaging the drives in your storage array:
•Prevent electrostatic discharge (ESD):
◦Keep the drive in the ESD bag until you are ready to install it.
◦Do not insert a metal tool or knife into the ESD bag.
Open the ESD bag by hand or cut the top off with a pair of scissors.
◦Keep the ESD bag and any packing materials in case you must return a drive later.
3

◦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 drive.
•Handle drives carefully:
◦Always use two hands when removing, installing, or carrying a drive.
◦Never force a drive into a shelf, and use gentle, firm pressure to completely engage the drive latch.
◦Place drives on cushioned surfaces, and never stack drives on top of each other.
◦Do not bump drives against other surfaces.
◦Before removing a drive from a shelf, unlatch the handle and wait 30 seconds for the drive to spin
down.
◦Always use approved packaging when shipping drives.
•Avoid magnetic fields:
◦Keep drives away from magnetic devices.
Magnetic fields can destroy all data on the drive and cause irreparable damage to the drive circuitry.
Replace drive in E5700 (24-drive shelf)
You can replace a drive in a 24-drive shelf.
About this task
The Recovery Guru in SANtricity System Manager monitors the drives in the storage array and can notify you
of an impending drive failure or an actual drive failure. When a drive has failed, its amber Attention LED is on.
You can hot-swap a failed drive while the storage array is receiving I/O.
Before you begin
•Review drive handling requirements in Requirements for E5700 drive replacement.
What you’ll need
•A replacement drive that is supported by NetApp for your controller shelf or drive shelf.
•An ESD wristband, or you have taken other antistatic precautions.
•A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Step 1: Prepare to replace drive (24-drive)
Prepare to replace a drive by checking the Recovery Guru in SANtricity System Manager and completing any
prerequisite steps. Then, you can locate the failed component.
Steps
1. If the Recovery Guru in SANtricity System Manager has notified you of an impending drive failure, but the
drive has not yet failed, follow the instructions in the Recovery Guru to fail the drive.
2. If needed, use SANtricity System Manager to confirm you have a suitable replacement drive.
a. Select Hardware.
4

b. Select the failed drive on the shelf graphic.
c. Click the drive to display its context menu, and then select View settings.
d. Confirm that the replacement drive has a capacity equal to or greater than the drive you are replacing
and that it has the features you expect.
For example, do not attempt to replace a hard disk drive (HDD) with a solid-state drive (SSD). Similarly,
if you are replacing a secure-capable drive, make sure the replacement drive is also secure-capable.
3. If needed, use SANtricity System Manager to locate the drive within your storage array: From the drive’s
context menu, select Turn on locator light.
The drive’s Attention LED (amber) blinks so you can identify which drive to replace.
If you are replacing a drive in a shelf that has a bezel, you must remove the bezel to see the
drive LEDs.
Step 2: Remove failed drive (24-drive)
Remove a failed drive to replace it with a new one.
Steps
1. Unpack the replacement drive, and set it on a flat, static-free surface near the shelf.
Save all packing materials.
2. Press the release button on the failed drive.
◦For drives in E5724 controller shelves or DE224C drive shelves, the release button is located at the top
of the drive. The cam handle on the drive springs open partially, and the drive releases from the
midplane.
3. Open the cam handle, and slide out the drive slightly.
4. Wait 30 seconds.
5. Using both hands, remove the drive from the shelf.
6. Place the drive on an antistatic, cushioned surface away from magnetic fields.
7. Wait 30 seconds for the software to recognize that the drive has been removed.
If you accidentally remove an active drive, wait at least 30 seconds, and then reinstall it. For
the recovery procedure, refer to the storage management software.
5

Step 3: Install new drive (24-drive)
You install a new drive to replace the failed one. Install the replacement drive as soon as possible after
removing the failed drive. Otherwise, there is a risk that the equipment might overheat.
Steps
1. Open the cam handle.
2. Using two hands, insert the replacement drive into the open bay, firmly pushing until the drive stops.
3. Slowly close the cam handle until the drive is fully seated in the midplane and the handle clicks into place.
The green LED on the drive comes on when the drive is inserted correctly.
Depending on your configuration, the controller might automatically reconstruct data to the
new drive. If the shelf uses hot spare drives, the controller might need to perform a complete
reconstruction on the hot spare before it can copy the data to the replaced drive. This
reconstruction process increases the time that is required to complete this procedure.
Step 4: Complete drive replacement (24-drive)
Confirm that the new drive is working correctly.
Steps
1. Check the Power LED and the Attention LED on the drive you replaced.
When you first insert a drive, its Attention LED might be on. However, the LED should go off within a
minute.
◦Power LED is on or blinking, and the Attention LED is off: Indicates that the new drive is working
correctly.
◦Power LED is off: Indicates that the drive might not be installed correctly. Remove the drive, wait 30
seconds, and then reinstall it.
◦Attention LED is on: Indicates that the new drive might be defective. Replace it with another new drive.
2. If the Recovery Guru in SANtricity System Manager still shows an issue, select Recheck to ensure the
problem has been resolved.
3. If the Recovery Guru indicates that drive reconstruction did not start automatically, start reconstruction
manually, as follows:
Perform this operation only when instructed to do so by technical support or the Recovery
Guru.
a. Select Hardware.
b. Click the drive that you replaced.
c. From the drive’s context menu, select Reconstruct.
d. Confirm that you want to perform this operation.
When the drive reconstruction completes, the volume group is in an Optimal state.
4. As required, reinstall the bezel.
6

5. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
What’s next?
Your drive replacement is complete. You can resume normal operations.

What’s next?
Your drive replacement is complete. You can resume normal operations.
Replace E5700 drive drawer (60-drive)
You can replace a drive drawer in an E5700 array.
About this task
The steps to replace a failed drive drawer in an E5760 controller shelf or a DE460C drive shelf depend on
whether the volumes in the drawer are protected by Drawer Loss Protection. If all volumes in the drive drawer
are in disk pools or volume groups that have Drawer Loss Protection, you can perform this procedure online.
Otherwise, you must stop all host I/O activity and power off the shelf before replacing the drive drawer.
Before you begin
•Review drive handling requirements in Requirements for E5700 drive replacement.
•Make sure the drive shelf meets all of these conditions:
◦The drive shelf cannot be over temperature.
◦Both fans must be installed and have a status of Optimal.
◦All drive shelf components must be in place.
◦The volumes in the drive drawer cannot be in a Degraded state.
14

Possible loss of data access — If a volume is already in a Degraded state, and you remove
drives from the drive drawer, the volume can fail.
What you’ll need
•A replacement drive that is supported by NetApp for your controller shelf or drive shelf.
•An ESD wristband, or you have taken other antistatic precautions.
•A flashlight.
•A permanent marker to note the exact location of each drive as you remove the drive from the drawer.
•Access to the storage array’s command line interface (CLI). If you do not have access to the CLI, you can
do one of the following:
◦For SANtricity System Manager (version 11.60 and above) — Download the CLI package (zip file)
from System Manager. Go to Settings ›System ›Add-ons ›Command Line Interface. You can then
issue CLI commands from an operating system prompt, such as the DOS C: prompt.
◦For SANtricity Storage Manager/Enterprise Management Window (EMW) — Follow the instructions
in the express guide to download and install the software. You can run CLI commands from the EMW
by selecting Tools ›Execute Script.
Step 1: Prepare to replace drive drawer (60-drive)
Prepare to replace a drive drawer by determining if you can perform the replacement procedure while the drive
shelf is online or if you need to stop host I/O activity and power off any of the shelves that are powered on. If
you are replacing a drawer in a shelf with Drawer Loss Protection, there is no need to stop host I/O activity and
power off any of the shelves.
Steps
1. Determine if the drive shelf is powered on.
◦If the power is off, you do not need to issue the CLI command. Go to Step 2: Remove cable chains.
◦If the power is on, go to the next step.
2. Type the following command on the command line, and press Enter:
SMcli <ctlr_IP1\> -p "array_password" -c "set tray [trayID] drawer
[drawerID]
serviceAllowedIndicator=on;"
where:
◦<ctlr_IP1> is the identifier of the controller.
◦array_password is the password for the storage array. You must enclose the value for
array_password in double quotation marks ("").
◦[trayID] is the identifier of the drive shelf that contains the drive drawer that you want to replace.
Drive shelf ID values are 0 to 99. You must enclose the value for trayID in square brackets.
◦[drawerID] is the identifier of the drive drawer that you want to replace. Drawer ID values are 1 (top
drawer) to 5 (bottom drawer). You must enclose the value for drawerID in square brackets. This
command ensures you can remove the top-most drawer in drive shelf 10:
15

SMcli <ctlr_IP1\> -p "safety-1" -c "set tray [10] drawer [1]
serviceAllowedIndicator=forceOnWarning;"
3. Determine if you need to stop host I/O activity, as follows:
◦If the command succeeds, you do not need to stop host I/O activity. All drives in the drawer are in pools
or volume groups with Drawer Loss Protection. Go to Step 2: Remove cable chains.
Possible damage to drives — Wait 30 seconds after the command completes before
you open the drive drawer. Waiting 30 seconds allows the drives to spin down, which
prevents possible damage to the hardware.
◦If a warning is displayed indicating that this command could not be completed, you must stop host I/O
activity before removing the drawer. The warning is displayed because one or more drives in the
affected drawer are in pools or volume groups without Drawer Loss Protection. To avoid losing data,
you must complete the next steps to stop host I/O activity and to power off the drive shelf and the
controller shelf.
4. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For
example, you can perform these steps:
◦Stop all processes that involve the LUNs mapped from the storage to the hosts.
◦Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.
◦Unmount all file systems associated with volumes on the array.
The exact steps to stop host I/O operations depend on the host operating system and
the configuration, which are beyond the scope of these instructions. If you are not sure
how to stop host I/O operations in your environment, consider shutting down the host.
5. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary
storage array.
Possible data loss — If you continue this procedure while I/O operations are occurring, the
host application might lose data because the storage array will not be accessible.
6. Wait for any data in cache memory to be written to the drives.
The green Cache Active LED on the back of each controller is on when cached data needs to be written to
the drives. You must wait for this LED to turn off.
16

(1) Cache Active LED
7. From the Home page of SANtricity System Manager, select View Operations in Progress.
8. Wait for all operations to complete before continuing with the next step.
9. Power off the shelves as follows:
◦If you are replacing a drawer in a shelf with Drawer Loss Protection:
There is NO need to power off any of the shelves.
You can perform the replace procedure while the drive drawer is online, because the Set Drawer
Service Action Allowed Indicator CLI command completed successfully.
◦If you are replacing a drawer in a controller shelf without Drawer Loss Protection:
a. Turn off both power switches on the controller shelf.
b. Wait for all LEDs on the controller shelf to go dark.
◦If you are replacing a drawer in an expansion drive shelf without Drawer Loss Protection:
a. Turn off both power switches on the controller shelf.
b. Wait for all LEDs on the controller shelf to go dark.
c. Turn off both power switches on the drive shelf.
d. Wait two minutes for drive activity to stop.
Step 2: Remove cable chains
Remove both cable chains so you can remove and replace a failed drive drawer. The left and right cable
chains allow the drawers to slide in and out.
About this task
Each drive drawer has left and right cable chains. The metal ends on the cable chains slide into corresponding
vertical and horizontal guide rails inside the enclosure, as follows:
•The left and right vertical guide rails connect the cable chain to the enclosure’s midplane.
•The left and right horizontal guide rails connect the cable chain to the individual drawer.
Possible hardware damage — If the drive tray is powered on, the cable chain is energized until
both ends are unplugged. To avoid shorting out the equipment, do not allow the unplugged cable
chain connector to touch the metal chassis if the other end of the cable chain is still plugged in.
Steps
1. Make sure host I/O activity has stopped and the drive shelf or controller shelf is powered off, or issue the
Set Drawer Attention Indicator CLI command.
2. From the rear of the drive shelf, remove the right fan canister:
a. Press the orange tab to release the fan canister handle.
The figure shows the handle for the fan canister extended and released from the orange tab on the left.
17

(1) Fan canister handle
b. Using the handle, pull the fan canister out of the drive tray, and set it aside.
c. If the tray is powered on, ensure that the left fan goes to its maximum speed.
Possible equipment damage due to overheating — If the tray is powered on, do not
remove both fans at the same time. Otherwise, the equipment might overheat.
3. Determine which cable chain to disconnect:
◦If the power is on, the amber Attention LED on the front of the drawer indicates the cable chain you
need to disconnect.
◦If the power is off, you must manually determine which of the five cable chains to disconnect. The
figure shows the right side of the drive shelf with the fan canister removed. With the fan canister
removed, you can see the five cable chains and the vertical and horizontal connectors for each drawer.
The top cable chain is attached to drive drawer 1. The bottom cable chain is attached to drive drawer 5.
The callouts for drive drawer 1 are provided.
