About Activating Zone Sets and Using the force Option

Once the zone sets have been created and populated, you must activate the zone set. When you activate
an IVR zone set, IVR automatically adds an IVR zone to the regular active zone set of each edge VSAN.
If a VSAN does not have an active zone set, IVR can only activate an IVR zone set using the force option,
which causes IVR to create an active zone set called "nozoneset" and adds the IVR zone to that active
zone set.
If you deactivate the regular active zone set in a VSAN, the IVR zone set is also deactivated. This occurs
Caution
because the IVR zone in the regular active zone set, and all IVR traffic to and from the switch, is stopped.
To reactivate the IVR zone set, you must reactivate the regular zone set.
If IVR and iSLB are enabled in the same fabric, at least one switch in the fabric must have both features

enabled. Any zoning related configuration or activation operation (for normal zones, IVR zones, or iSLB
zones) must be performed on this switch. Otherwise, traffic might be disrupted in the fabric.
You can also use the force option to activate IVR zone sets.
