host disconnect from vcenter during ucs maintenanc

[mattj710]

Anyone seen an issue with vmware on cisco ucs where the hosts disconnect from vcenter during a fabric interconnect reboot? Our setup is Two fabric interconnect that connect to chassis with b200 blade servers. We did a ucs upgrade and when one of our FI's rebooted, half of our hosts went to not responding in vcenter. They came back to normal after the FI came back up. I do not believe any vms disconnected. our vmware esxi hosts are 6.7u3, vcenter version 6.7u3F

How is your teaming and failover policy configured on the Management portgroups? Are you specifying more than one NIC as Active or StandBy?

In case of UCS are you applying the correct NIC to the correct FI on the Server Profile?

We figured out the issue, the management port group had one nic to set to active, the other set to unused. I moved the second nic on each host to standby.
