The following symptoms are observed: When performing a vMotion migration, you see this compatibility error: Currently connected network interface 'device' uses network 'network' NSX port group 'portgroup' (lcp.kcpSyncStatus down), which is not accessible The lcp.kcpSyncStatus component is down in the affected ESXi hosts. vCenter reads this information and blocks the vMotion: #net-dvs | grep lcp.kcpSyncStatus com.vmware.common.opaqueDvs.status.component.lcp.kcpSyncStatus = down , propType = RUNTIME In the affected ESXi host vmkernel.log file, you see entries similar to: 2021-04-28T20:17:28.001Z cpu24:2099002)kcp: KCP_CPProcessSessionCtrlMsg:1499: [nsx@6876 comp="nsx-esx" subcomp="kcp"]Init the control plane after receiving a session control open message2021-04-28T20:17:28.001Z cpu24:2099002)KCP_CPProcessSessionCtrlMsg:1532:[nsx@6876 comp="nsx-esx" subcomp="kcp"]Set the max message length 102402021-04-28T20:17:28.001Z cpu24:2099002)VLAN.vswitch: PVLAN_DVSUpdate:1023: [nsx@6876 comp="nsx-esx" subcomp="vswitch"]PVLAN mapping (2000,2001) can't be deleted - refCount 12021-04-28T20:17:28.001Z cpu24:2099002)WARNING: kcp: KCP_SetPSPropSyncCall:242: [nsx@6876 comp="nsx-esx" subcomp="kcp"]Failed to set com.vmware.vswitch.pvlanMap on portset DvsPortset-1, set outOfSync : Busy
The ESXi host property com.vmware.vswitch.pvlanMap on a DvsPortset (Distributed Switch) has a conflict. It's a global property on a vswitch, but NSX-T and vCenter are both setting values to it. NSX-T tries to delete/update the vCenter created PVLAN mapping and fails, and keeps retrying.
This is a known issue affecting NSX-T Data Center 3.1.1, 3.1.2, and 3.1.3This issue is resolved in VMware NSX-T 3.1.3.3 (build number 18844959)
To workaround this issue, delete the private vlans (PVLAN) that are configured in the specific DVS (DvsPortset-X) that shows in the vmkernel.log error message, i.e:2021-04-28T20:17:28.001Z cpu24:2099002)VLAN.vswitch: PVLAN_DVSUpdate:1023: [nsx@6876 comp="nsx-esx" subcomp="vswitch"]PVLAN mapping (2000,2001) can't be deleted - refCount 12021-04-28T20:17:28.001Z cpu24:2099002)WARNING: kcp: KCP_SetPSPropSyncCall:242: [nsx@6876 comp="nsx-esx" subcomp="kcp"]Failed to set com.vmware.vswitch.pvlanMap on portset DvsPortset-1, set outOfSync : BusyTo check the actual DVS name for a given DvsPortset-X, you can run:#net-dvs | egrep "com.vmware.common.alias|com.vmware.common.host.portset" com.vmware.common.alias = dvs-compute , propType = CONFIG com.vmware.common.host.portset = DvsPortset-0 , propType = CONFIG com.vmware.common.alias = NVDS-OVERLAY , propType = CONFIG com.vmware.common.host.portset = DvsPortset-1 , propType = CONFIG
