PURPOSE:To exclude the waste of input/output retrial by applying input/output retrial path having a high probability of success of the input/output retrial at a fault of input/output. CONSTITUTION:An input/output decision means 1 judges whether or not the result of input/output is normal to decide whether or not the input/output retrial is to be applied. Then an input/output retrial decision means 2 uses the means 1 to decide the result of output is in error, then the means 2 decides an input/ output path having a high probability of success for the input/output retrial while referencing the input/output list 4. Then an input/output retrial means 3 applies input/output retrial via an input/output path decided by the means 2. Thus, number of times of the input/output retrial is minimized and the waste in the input/output retrial is excluded. |
