During the NSX-T Manager bring-up process, SDDC Manager creates a VM anti-affinity rule to prevent the VMs of the same NSX-T Manager cluster from running on the same ESXi host. If you redeployed all NSX-T Manager cluster nodes, you must recreate this rule. If you redeployed one or two nodes of the cluster, you must add the new VMs to the existing rule.
