Issue/Introduction

After migrating a Supervisor enabled cluster to another vSphere Distributed Switch the vCenter wcp service is not able to start because a port group is missing

 

Starting the wcp service manually fails:

root@############ [ ~ ]# service-control --start wcp
Operation not cancellable. Please wait for it to finish...
Performing start operation on service wcp...
Error executing start on service wcp. Details {
    "detail": [
        {
            "id": "install.ciscommon.service.failstart",
            "translatable": "An error occurred while starting service '%(0)s'",
            "args": [
                "wcp"
            ],
            "localized": "An error occurred while starting service 'wcp'"
        }
    ],
    "componentKey": null,
    "problemId": null,
    "resolution": null
}
Service-control failed. Error: {
    "detail": [
        {
            "id": "install.ciscommon.service.failstart",
            "translatable": "An error occurred while starting service '%(0)s'",

        }
    ],

}

wcp logs show a missing port group:

/var/log/vmware/wcp/wcpsvc.log

Environment

vCenter 8.0 U3

Cause

Distributed Virtual Switch (DVS) portgroup migration is not supported on clusters with active Supervisors. The wcp service expects portgroups will always remain attached to the DVS spanning the clusters' hosts.

Resolution

Workaround: Roll back the DVS migration to the original DVS / port groups in order to be able to start the wcp service again. 

 

Note: Migrating a Supervisor-enabled cluster to another vSphere Distributed Switch is currently not supported.
