When performing a restart or failover of our DataMiner system, one of the NICs becomes unusable.
Even sending out a ping over that NIC stops working.
Disabling & Enabling the NIC again solves the issue (until the next restart).
Does someone know the exact set of actions that are performed on the NIC during startup/failover?

Hi Ive,
Do you have this for all your DMA's?
Could you also share some more information on the Windows version, DataMiner version, driver and HW info on your adaptor?

Could it be related with assigning the virtual IP?
Hi Michiel,
Thank you for your response.
My cluster contains only one DMA (failover pair).
The system is running DataMiner 10.0.9 on windows server 2012R2.
The NICs are “RedHat Virt IO” network adaptors (which have been working fine for the the last 2 years).
I have 4 NICs but only the primary dataminer nic has this problem.
The logging shows no errors.
