progress.
Only one zoning related action can occur at the same time
(zone, IVR zone, or iSLB zone configuration or activation).
Wait until the zone set activation completes and then retry
the iSLB zone set activation.
Zoning database is locked because a
configuration is pending.
Only one zoning related action can occur at the same time
(zone, IVR zone, or iSLB zone configuration or activation).

changes.
