It was two node metrocluster but due to business requirement we configured it as a single node (non-ha) system. Model: FAS8040. It was running fine with one node configuration since more then couple of years.
Today we did an upgrade from 8.3.1P1 to 9.1P10. As soon as we reboot the node. It is continually giving us below error and not booting ONTAP.
[rscnas01:fci.adapter.error:notice]: Fibre Channel adapter driver encountered error "disabling non-NetApp 8324 hardware" on 1a [rscnas01:fci.adapter.error:notice]: Fibre Channel adapter driver encountered error "disabling non-NetApp 8324 hardware" on 1b [rscnas01:kern.version.change:notice]: Data ONTAP kernel version changed from 8.3.1P1 to 9.1P10 CRITICAL: Metrocluster is configured but HAOSC is not configured correctly. Use the maintenance mode command "ha-config modify" on this node to correct the problem. This node cannot continue to boot and will now halt.
We verified ha-config show setting for both controller and chassis. Both are already set to "non-ha"
We also tried after removing the FCVI adapter hardware but its still giving us same above error.
You should remove the FCVI card if the system is no longer a MCC node - unless the card is in slot one AND the system is set as mcc, it will report this error under 9.1 and later. I see a similar case that resolved by powering the system down completely and then powering it back on.
