Hello toasters,

I'm interested to know if anyone else has found recently that volumes containing LUNs have gone into the 'NVFAIL' state during an ONTAP upgrade or other event that causes an HA failover?

It's not something we have ever specified on volume creation; documentation suggests that it should be disabled by default however all of our volumes containing LUNs appear to have NVFAIL enabled. My *perception* this is a change since we upgraded to ONTAP 9.8.

The documentation seems live under Metrocluster; our affected system is not a Metrocluster: https://docs.netapp.com/us-en/ontap-metrocluster/manage/concept_monitoring_a...

It's also odd as the KB article says: - This affords no extra protection for Storage Area Network (SAN) hosts because SAN hosts reference LUNs by the LUN number assigned via LUN maps and NOT by the LUN name. - This protection was designed for file protocols, such as Network File System (NFS) and Common Internet File System protocol (CIFS), protect against corruption due to NVFAIL.

Taken from here: https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP...

So it also seems like either the setting or the documentation is the wrong way round to me...

Looking for feedback to see if anyone else has experienced this or if there's something obvious we've missed before I raise a support call.

Cheers, Steve
