DS460C Disk-Drive Hot Swap: Identify the Failed Drive and Restore Ownership

Before you begin

Verify that the replacement drive is supported for the actual DS460C configuration in NetApp Hardware Universe. All other system components must be functioning correctly; otherwise contact technical support. Replace the identified failed drive, not a drive selected only from a photograph.

storage disk show -broken

The target should appear in the broken-drive list. If it does not, wait and check again; the source notes that drive type and capacity can make this take several hours. For self-encrypting disks, follow the extra before/after steps for the actual ONTAP version in the NetApp encryption documentation.

Preparation and handling

• Keep the replacement in its ESD bag until ready; open by hand or cut the top with scissors. Do not insert a knife or metal tool into the bag.
• Use a grounded ESD wrist strap on an unpainted chassis surface. If unavailable, touch an unpainted enclosure-chassis surface before handling the drive.
• Support the drive with both hands. Do not touch the exposed board underneath the carrier. Set drives on an antistatic cushioned surface; do not stack, bump or place them near magnetic devices.

Before hot swap, install the applicable current Disk Qualification Package(DQP), so newly qualified drives are recognized and unsupported partitioning/events are avoided. DQP also reports non-current drive firmware. Check supported shelf/IOM firmware and drive firmware before adding shelves, shelf FRUs or SAS cables. The source describes automatic nondisruptive firmware updates for applicable new drives and a two-minute firmware-check interval; use the actual release’s supported firmware process.

Optionally locate the shelf with its blue LEDs:

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

There are three shelf location LEDs: one on the operator panel and one on each IOM. They remain illuminated for 30 minutes; use the same command with off to turn them off sooner. Refer to the matching shelf-LED documentation for component indication details.

The DS460C has five drawers, numbered 1 at the top through 5 at the bottom, with 12 drive slots per drawer. Slot numbers within each drawer run 0 through 11; use the physical slot map below:

1. Check ownership auto-assignment if manual assignment is needed

If manually assigning replacement-drive ownership, first check auto-assignment. The source requires manual assignment when drives in the stack are owned by both controllers of an HA pair. Otherwise continue with the appropriate automatic path.

storage disk option show

The Auto Assign column shows on when enabled. If the manual-assignment procedure requires disabling it, run the following for each relevant controller, using the actual node name:

storage disk option modify -node node_name -autoassign off

Record the prior state for both HA nodes. The source misspells this option as -autodassign; the corrected option is -autoassign. Reenable only as appropriate for the prior configuration.

2. Ground yourself, unpack and identify the failed drive

Ground yourself, unpack the replacement and set it on a level surface near the shelf. Match the console warning to the amber Attention LED on the correct drawer. These 2.5-inch/3.5-inch SAS carriers do not have their own LEDs; inspect the drawer indicators in front of the drives. The drawer attention indicator blinks to identify the drawer. The per-drive attention location is at the front-left, ahead of the warning symbol on the drive handle.

3. Open the correct drawer

Pull both levers to unlatch it. Use the extended levers to carefully draw it out until it stops. From above, identify the Attention LED in front of the failed drive; verify the slot before releasing the carrier.

4. Remove the failed drive

Gently pull back the orange release latch in front of the target drive:

Open the cam handle and lift the drive only slightly. Wait 30 seconds, then use the cam handle to lift the drive out completely. Support its weight and place it on an antistatic cushioned surface away from magnetic devices:

5. Insert and secure the replacement

Raise the replacement drive’s cam handle vertically. Align the two raised buttons on each side of its carrier with the matching gaps in the drawer drive channel:

Lower the drive straight down. Rotate the cam handle down until it clicks beneath the orange release latch. Slowly push the drawer back into the enclosure:

Do not slam the drawer shut. A jolt can damage the array or interrupt access. The source’s literal Chinese wording says never close the drawer; that is a translation error. Close it gently, then move both levers toward the center to latch it. The green activity indicator on the drawer front comes on when the replacement is inserted correctly. For another failed drive, repeat identification, opening, removal and insertion for that drive.

6. Check the LEDs

The Attention LED can initially illuminate after insertion, but should go out within one minute. A photograph of insertion alone is not a completed health check.

7. Assign ownership and restore the recorded auto-assignment state

If the manual-ownership branch was used, list unassigned disks and assign each verified replacement to the intended controller:

storage disk show -container-type unassigned
storage disk assign -disk disk_name -owner owner_name

The source’s garbled assignment text is corrected above. Wildcards can target multiple disks; verify the selected set and owner before using them. If auto-assignment was disabled earlier and should be restored, run the following on each applicable HA node:

storage disk option modify -node node_name -autoassign on

This is a stored translation of the replacement procedure, checked against the matching NetApp English page. No disk removal, ownership command, firmware update or storage operation was run.
