DS212C / DS224C: Replace a Failed Drive in the Source Shelf Workflow

This translates the stored DS212C/DS224C failed-drive hot-swap procedure. The same official English procedure was found. Match the actual shelf/IOM generation, ONTAP release, drive qualification, redundancy and encryption requirements before servicing.

Firmware and locating the shelf

The source describes background automatic drive-firmware updates for qualified replacement drives, with checks every two minutes. Confirm the actual configuration rather than assuming an update is enabled on every system. To locate the intended shelf, its optional blue-location-LED command is:

storage shelf location-led modify -shelf-name <SHELF_NAME> -led-status on

There are three location LEDs: the operator panel and each IOM. The source gives a 30-minute illumination interval; use the corresponding off setting to clear them when finished. Consult the matching shelf LED guide for locations/meaning.

Confirm the failed drive and prerequisites

storage disk show -broken

The source requires the removed drive to be listed as failed. Depending on type/capacity, appearance can take hours; do not pull a healthy/active drive merely because a guessed slot is nearby. Check that other components are healthy and that the intended replacement is supported in Hardware Universe.

For an SED, follow the additional before/after replacement steps for the actual ONTAP encryption configuration. Have the applicable Disk Qualification Package, shelf/IOM firmware and drive firmware in place as required so a qualified replacement is recognized; the source warns that stale qualification information can block recognition/partitioning.

ESD and handling

Keep the drive in its ESD bag until ready; open by hand or cut the bag top rather than inserting a metal tool/knife. Use a grounded ESD strap on an unpainted chassis surface; the source gives touching that surface first as its fallback when a strap is unavailable.

Support the drive with both hands and do not touch the exposed board under the carrier. Use a cushioned surface, do not stack or strike drives, and keep them away from damaging magnetic sources.

1. Determine automatic or manual ownership assignment

If this shelf/HA layout requires manual assignment, disable automatic assignment only after checking its current state and intended owners. The source specifically calls out stacks whose drives belong to both controllers. If automatic assignment is appropriate, this preparatory disable step is unnecessary.

storage disk option modify -node <NODE_NAME> -autoassign off

For the applicable HA workflow, check/configure both nodes as instructed. The source typo -autodassign is corrected to -autoassign, confirmed by the official command reference. Record the prior state for later restoration.

2. Ground yourself, unpack and identify the exact carrier

Prepare the replacement on a level surface near the shelf. Correlate console diagnostics, drive identity and amber attention LED. The failed drive may show a steady green activity LED because it is powered, but should not be conducting normal blinking I/O in this source workflow.

3. Release the carrier using the correct orientation

Press its release button and fully open the cam handle to disengage the drive. DS212C carriers are horizontal with the button at the left of the face:

DS224C carriers are vertical with the button at the top of the face:

4. Remove, wait and insert

Slide the failed drive out slightly to let an HDD safely spin down, which the source says can take up to one minute, then remove it while supporting its weight. Do not rush a rotating drive.

Wait at least 10 seconds after removal before inserting the replacement so the system detects the removal. These are distinct requirements: the possible HDD spin-down wait does not replace the post-removal detection interval.

With the replacement cam handle open, support it with both hands, slide it firmly to the stop and slowly close the handle until seated/latching correctly. Keep hands away from the exposed underside board. Repeat the correct identification/removal/insertion checks for any additional failed drive only when the system’s redundancy/service procedure permits it.

5. Verify LEDs, ownership and return to the intended configuration

A steady green activity LED means power; blinking indicates I/O or automatic firmware work in the documented case. It is not by itself proof of completed rebuild or restored data protection. Confirm the actual system’s replacement and recovery status.

If manual assignment was selected, inspect only the intended unassigned replacement and assign it to its verified owner:

storage disk show -container-type unassigned
storage disk assign -disk <DISK_NAME> -owner <OWNER_NAME>

The source’s garbled assign command is corrected above. Although it mentions wildcards for multiple disks, do not blanket-assign unrelated disks. Restore the previously intended auto-assignment state on the required nodes:

storage disk option modify -node <NODE_NAME> -autoassign on

Use on only where the pre-maintenance/intended policy calls for it. Follow the applicable failed-part return instructions after completing the validated service workflow.
