Abstract
According to one embodiment, a storage medium stores a program for causing a computer to: execute first processing of determining whether there is a failure in a magnetic disk device based on log information of the magnetic disk device; in a case where it is determined in the first processing that the magnetic disk device has failed, execute second processing of determining whether the magnetic disk device is continuously used by depopulation processing; and determine a treatment of the magnetic disk device based on results of the first processing and the second processing.
Claims15
A storage medium storing a program for causing a computer to:
- execute first processing of determining whether there is a failure in a magnetic disk device based on log information of the magnetic disk device;
- in a case where it is determined in the first processing that the magnetic disk device has failed, execute second processing of determining whether the magnetic disk device is continuously used by depopulation processing;
- and
- determine a treatment of the magnetic disk device based on results of the first processing and the second processing.
A magnetic disk device comprising a computer configured to execute determination processing in response to a command from a host, wherein
- the determination processing includes:
- executing first processing of determining whether there is a failure of the magnetic disk device based on log information;
- executing second processing of determining whether the magnetic disk device is continuously used by depopulation processing in a case where it is determined in the first processing that the magnetic disk device has failed;
- and
- determining a treatment of the magnetic disk device based on results of the first processing and the second processing.
A data center system comprising:
- a magnetic disk device;
- and
- a host, wherein
- the host includes a computer configured to:
- execute first processing of determining whether there is a failure in the magnetic disk device based on log information of the magnetic disk device;
- in a case where it is determined in the first processing that the magnetic disk device has failed, execute second processing of determining whether the magnetic disk device is continuously used by depopulation processing;
- and
- determine a treatment of the magnetic disk device based on results of the first processing and the second processing.
