Hello,

due to vulnerability issue, the HCI mnode shutdown over few months, we want to upgrade storage node OS, after power on mnode and access mnode IP, display as below

access https://mnode_IP:442 no problem

ssh check with mnode listen as below

search NetApp support website did not found any procedure for troubleshoot, how can recover mnode for upgrade storage node?

In addition to the KBs, product documentation has a procedure for recovery

https://docs.netapp.com/us-en/hci/docs/task_mnode_recover.html

Usually there's no valuable long term data in mNode, so you can simply re-deploy HCC (Management Service) if VM is still viable.

If VM isn't viable, you can redeploy the VM using mNode OVA, and then deploy HCC.

If your mNode is not allowed to get out to the Internet, you would have to download mNode and Management Services archive file (this would be uploaded to mNode before completing deployment).

You can find a list of Management Services releases and links to their release notes at

https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/Management_services_for_Element_Software_and_NetApp_HCI/Management_Services_Release_Notes

As @Ontapforrum said, it's a good idea to get someone from Support booked for a Web meeting when you go to do this, if you haven't done it before.
