US 2011/0035546 A1 · MANAGEMENT DEVICE AND MANAGEMENT METHOD

Abstract

Timing at which a rotation of a physical disk can stop is taken to more appropriately stop the rotation of the physical disk. A management device for managing a storage device and a server includes a first recording part in which an identification number of a logic volume and a rotational state of the physical disk are recorded, a second recording part in which an operating state of the server and an identification number of the logic volume to be accessed by the server are recorded, an updating part for changing the operating state of the server recorded in the second recording part when the operating state of the server is changed, an extracting part for extracting an operating state of another server to access another logic volume of the physical disk having the logic volume to be accessed by the server set from the second recording part based on the identification number of the logic volume to be accessed by the server recorded on the first recording part, and an instructing part for giving an instruction to the storage device for changing the rotation state of the physical disk depending on the operating state after the server is changed and the operating state of the other server.

Dependent claims

A management device to manage a storage device having physical disks in which logical volumes are set and servers of which an access target is the logical volume, the management device comprising:

a first recording unit to record an identification number of the logical volume and a rotating status of the physical disk;
a second recording unit to record an operating status of the servers and the identification number of the logical volume as the access target of the servers;
an updating unit to change, if the operating status of one server is changed, the operating status of the one server recorded in the second recording unit;
an extracting unit to extract, based on the identification number of one logical volume as the access target of the one server that is recorded in the first recording unit, an operating status of another server of which an access target is another logical volume of the physical disk in which the one logical volume as the access target of the one server is set from the second recording unit;
and
an instructing unit to instruct the storage device to change a rotating status of the physical disk, corresponding to a post-changing operating status of the server and the operating status of the another server.

A management method for a management device that manages a storage device having physical disks in which logical volumes are set and servers of which an access target is the logical volume, the method comprising:

recording an identification number of the logical volume and a rotating status of the physical disk in a first recording unit;
recording an operating status of the servers and the identification number of the logical volume as the access target of the servers in a second recording unit;
changing, if the operating status of one server is changed, the operating status of the one server recorded in the second recording unit;
extracting, based on the identification number of one logical volume as the access target of the one server that is recorded in the first recording unit, an operating status of another server of which an access target is another logical volume of the physical disk in which the one logical volume as the access target of the one server is set from the second recording unit;
and
instructing the storage device to change a rotating status of the physical disk, corresponding to a post-changing operating status of the server and the operating status of the another server.

A computer-readable recording medium storing a management program to make a management device that manages a storage device having physical disks in which logical volumes are set and a servers of which an access target is the logical volume, execute:

recording an identification number of the logical volume and a rotating status of the physical disk in a first recording unit;
recording an operating status of the servers and the identification number of the logical volume as the access target of the servers in a second recording unit;
changing, if the operating status of one server is changed, the operating status of the one server recorded in the second recording unit;
extracting, based on the identification number of one logical volume as the access target of the one server that is recorded in the first recording unit, an operating status of another server of which an access target is another logical volume of the physical disk in which the one logical volume as the access target of the one server is set from the second recording unit;
and
instructing the storage device to change a rotating status of the physical disk, corresponding to a post-changing operating status of the server and the operating status of the another server.
