Prepared from the cast-off control method and system administration

The present invention relates to a cast-off control method and system prepared from the cast, the method comprising the steps of: acquiring information prepared from the cast of the device due to failure of the operation; weighted number calculation automatic switching operation of each attribute is obtained the serial number of equipment failure; size sequence number of the failed device sequentially N-1 to obtain cast back and checked according to the policy table; prepared from the corresponding vote cast back according to the policy table cast back. Cast back control method of the automatic switching apparatus, since the automatic switching master increased number of coefficients by a weighting operation of the main sorting prepared from the cast causing operation failure by the apparatus, without causing the operation of the main prepared from the cast sorting device forward fault, thereby to cause the fault checking apparatus main automatic switching operation of the N-1 in the checking process, then checking apparatus main cause failure prepared from the cast operation, prepared from the cast to avoid from the prior to its standby oneself in check and lead to inaccurate checking further lead prepared from the cast cast back control is not accurate.
