Prioritizing volume accesses in multi-volume storage device based on execution path of a service

A service management method implemented by a computer, the service management method comprising:

• acquiring respective execution times of programs that implement a service;
• identifying a first volume having a largest influence on a response time of the service based on the respective execution times of the programs, where the first volume being any one of volumes of a storage device, and at least one of the programs writing and reading data to and from the storage device;
• and
• setting a priority of writing and reading of data to and from the first volume higher than priorities of writing and reading of data to and from a second volume that is any one of the volumes other than the first volume.

A non-transitory computer-readable storage medium storing a service management program that causes a computer to execute a process, the process comprising:

• acquiring respective execution times of programs that implement a service;
• identifying a first volume having a largest influence on a response time of the service based on the respective execution times of the programs, where the first volume being any one of volumes of a storage device, and at least one of the programs writing and reading data to and from the storage device;
• and
• setting a priority of writing and reading of data to and from the first volume higher than priorities of writing and reading of data to and from a second volume that is any one of the volumes other than the first volume.
