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.

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.
