MS Server 2019 MS Failover cluster physical mgmt cluster nic connection fails
We have a 2 Node MS Failovercluster on Windows Server 2019 in use. The network configuration is based on several physical multiport nics where the Hyper-V Switch is on Broadcom 10GBit 57412 NIC´s SET teaming and servicing the cluster VM´s and CSV network. The Cluster management network is an separate Intel 1 GBit 350 -T4 NICs as Host-based LBFO teaming and generally working as designed. During the backup hours in the night the cluster management network is producing Cluster Event ID´s 1126 and 1129 and the Cluster configuration cannot be accessed in a timely manner. The problem is repeating each night and can be reproduced if we schedule the backup during the day. Accessing and working with the VM´s isn´t affected during the backup. The cluster metrics are set like this: Name Metric AutoMetric ---- ------ ---------- CSV LM 30080 True ISCSI BACKEND 70241 True MGMT CLUSTER 70368 True VM ACCESS CLUSTER 70080 True Our general question is, if we should replace the Intel 1 GBit NIC´s with 10 GBit NIC´s or is there a misconfiguration in the teaming or network settings?
