Hi NetApp Community,I hope this message finds you well. I'm reaching out to kindly request access to the following Knowledge Base article:
KB Title:
DS4486_Shelf_flashes_H1_evacuation_state_after_disk_carrier_replacement
Background & Context:We are currently managing a DS4486 disk shelf environment and recently encountered a situation where, after replacing a disk carrier, the shelf continues to display H1 evacuation state on the operator display panel.As documented in the DS4486 Installation and Service Guide, the H1 shelf mode is initiated automatically when one disk drive in a carrier faults and data from the good disk drive is being copied to a spare. During this state, the system prevents removal of any faulted disk carrier to protect data integrity. However, in our case, the H1 state appears to persist beyond the expected evacuation window even after the carrier replacement has been completed.Why I need this KB:I have reviewed the standard DS4486 documentation, but it does not provide specific troubleshooting steps for scenarios where the H1 evacuation state remains active after a disk carrier has already been replaced. I believe this particular KB article contains targeted guidance or known issues related to this specific behavior.Important Note:I understand that this KB article was archived in January 2026 and is no longer publicly accessible through the standard NetApp Support portal search. This is precisely why I am turning to the community in the hope that someone may still have a copy of the original content or the key troubleshooting steps documented within it.If anyone from the NetApp support team or community has access to this archived KB and could share the contents or key troubleshooting steps, it would be greatly appreciated.Additional Details (if helpful):
- Shelf Model: DS4486
- Issue: H1 evacuation state persists post disk carrier replacement
- System: ONTAP environment with multi-disk carriers
Thank you very much for your time and assistance!
