Data ONTAP API Failed

FilipeAlhandro — Wed, 04 Jun 2025 10:08:20 GMT

Hello,

One of our NetApp's have this error:

Data ONTAP API Failed: Internal error. Cannot retrieve information for LIFs with role "cluster-mgmt" while vifmgr is offline. Wait a few minutes, then try again. If problem persist, contact your administrator. (Erro 13001)

The two nodes within display:

The "a" node as "offline" while the "b" node as a refused connection

The error message occurs when the admin tries to login through the GUI and subsequently blocks the logon process.

SSH-ing to the CLI Management interface works as per normal.

Desperate for any help.

Thank you kindly.

Filipe.

Hmm, something is wrong here. Can you go through the commands here on this KB and see if anything jumps out as incorrect?

system health status show

system health alert show

There are more commands in the KB I referenced. That would give more information.

way more.

I guess what I sent is a good start point, the KB is pretty extensive and definitely useful to dig in further
