How do I remove a VSM from vCenter?
A VSM can only be removed from VMware vCenter server using the “no vmware dvs ” command under the svs connection. You cannot remove the DVS from within vCenter. If you removed or destroyed the VSM without issueing the above command the old Nexus 1000V will remain in vCenter until you run the following steps. You will need to reconnect the existing VSM or create a new VSM with the same extension key to VMware vCenter to remove it.
