Abstract: A storage apparatus is provided with a virtualization mechanism which manages first and second LPARs (logical partitions) assigned respectively with first and second logical resources acquired by logically partitioning physical resources in the storage apparatus. The virtualization mechanism provides a shared memory area which is an area based on a memory and can be accessed by the first and second LPARs. The first LPAR stores information required for taking over a data input/output process handled by the first LPAR to the second LPAR, in the shared memory area. When detecting that a fault occurs in the first LPAR, the second LPAR acquires the information required for taking over from the shared memory area and takes over and executes the data input/output process formerly handled by the first LPAR on the basis of the information required for taking over.
