The present invention discloses a Virtualized Network Function Manager (VNFM) failure repairing method, which includes that: failure detection information of each VNFM is acquired according to a set detection cycle; and when it is determined based on the failure detection information that any VNFM fails, a failure repairing instruction of repairing the any VNFM is sent to a preset Virtualized Infrastructure Manager (VIM). The present invention also discloses a monitor, a VIM, a VNFM and a storage medium. By implementing the solutions, a VNFM failure may be automatically repaired, the VNFM failure repairing speed and efficiency may be effectively improved, and the reliability of the VNFM and the running stability and maintenance stability of a Virtualized Network Function (VNF) are effectively improved.
