Abstract:
1. A computer system, comprising: a computer that includes a memory, an output module, and an input module; a first storage subsystem that is connected to the computer, includes a first logical volume for storing data, and transfers replicated data of data stored in the first logical volume; and a second storage subsystem that is connected to the computer and to the first storage subsystem, includes a second logical volume associated with the first logical volume as a copy pair mate and storing replicated data, and receives the replicated data from the first storage subsystem, wherein, the computer: acquires copy pair status information concerning the status of copy pair of the first logical volume and the second logical volume, and storing it in the memory; when receiving an operational status presentation request, refers to the memory and acquires, based on information indicating the copy pair status, a performance correlation between a plurality of resources from a management table stored in the memory; and displays information on the performance correlation between the resources on the output module based on the acquired information wherein said first storage subsystem comprises a first storage area and transfers replicated data of data stored in said first storage area; wherein said second storage subsystem connected to said first storage subsystem via a communication line comprises a second storage area and receives replicated data to be stored from said first storage subsystem to said second storage area; wherein said computer system further includes: a replication processing status referral unit for referring to a replication processing status of data of said first storage area and said second storage area to be associated; wherein said replication processing status referral unit refers to a replication processing status showing whether said replicated data has been transferred from said first storage subsystem to said second storage subsystem; and an output unit for outputting, when said first storage area is designated, first performance information concerning data I/O stored in said first storage area, and outputting second performance information concerning data I/O stored in said second storage area together with said first performance information upon said replicated data being in replication processing from said first storage area to said second storage area as a result of referring to said replication processing status, and wherein said output unit outputs second performance information concerning data I/O stored in said second storage area together with said first performance information when said replicated data is being transferred.
