Abstract

An information processing apparatus connecting a plurality of hard disks rebuilds data stored in one hard disk of the plurality of hard disks to another hard disk of the plurality of hard disks. The information processing apparatus is controlled in such a manner that when the information processing started, the rebuild is not resumed immediately after the information processing apparatus is started, and the rebuild is resumed after a predetermined time has elapsed.

Claims

1. An information processing apparatus connecting a plurality of hard disks, comprising:

a rebuild unit configured to rebuild data stored in one hard disk of the plurality of hard disks to another hard disk of the plurality of hard disks; and

a control unit configured to control the information processing apparatus so that, the rebuild unit is prevented from resuming the rebuild immediately after the information processing apparatus is started, and the rebuild is resumed after a predetermined time has elapsed.

2. The information processing apparatus according to claim 1, further comprising a determination unit configured to determine whether a rebuild by the rebuild unit is interrupted when the information processing apparatus is started;

wherein the control unit controls the information processing apparatus so that, when the determination unit determines that the rebuild is interrupted, the rebuild unit is prevented from resuming the rebuild immediately after the information processing apparatus is started, and the rebuild is resumed after a predetermined time has elapsed.

3. The information processing apparatus according to claim 2, further comprising a checking unit configured to check, when the information processing apparatus has been started, whether the start was caused by turning on a power supply or by returning from a sleep state,

wherein if it is determined that the start was caused by turning on the power supply, when a predetermined time set in the rebuild unit passes after the information processing apparatus has been started, the control unit causes the rebuild unit to resume the rebuild, or if it is determined that the start was caused by returning from a sleep state, after the information processing apparatus is started, the control unit causes the rebuild unit to immediately resume the rebuild.

4. The information processing apparatus according to claim 2, further comprising a retaining unit configured to retain information indicating that the rebuild has been interrupted when the rebuild by the rebuild unit was interrupted,

wherein the determination unit determines whether the rebuild is interrupted according to whether the information that the rebuild has been interrupted is retained in the retaining unit.

5. A control method for an information processing apparatus connecting a plurality of hard disks, the control method comprising:

rebuilding data stored on one hard disk of the plurality of hard disks to another hard disk of the plurality of hard disks; and

controlling the information processing apparatus so that, the rebuild is prevented from being resumed immediately after the information processing apparatus is started, and the rebuild is resumed after a predetermined time has elapsed.

6. A computer-recordable medium storing a computer-executable instructions to cause a computer to execute the control method according to claim 5.
