An information processing method executed by a processor included in an information processing device includes acquiring, when an error occurred at the information processing device is detected, first identification information that include identification information of a transmission source of a first packet transmitted or received when the error has occurred and identification information of a transmission destination of the first packet; receiving a second packet; determining whether second identification information included in the second packet matches with the first identification information, the second identification information including identification information of a transmission source of the second packet and identification information of a transmission destination of the second packet; storing data corresponding to the second packet when it is determined that the second identification information matches with the first identification information; and transmitting the data to a management device that analyzes the error when an instruction is received from the management device.

Information processing method, device and recording medium for collecting logs at occurrence of an error

A storage controller that controls a virtual storage apparatus is provided, the storage controller includes: a performance measuring unit that obtains performance information on a plurality of volumes present in the virtual storage apparatus; a grouping unit that groups the plurality of volumes into a plurality of performance groups, each of the plurality of performance groups having a different performance requirement, based on the performance information on the plurality of volumes and a grouping rule; and a storage pool managing unit that adds, to a storage pool, one of volumes grouped into the plurality of performance groups until a requirement condition for the storage pool is met, the performance groups from which a virtual volume being to be reserved.

Storage controller, virtual storage apparatus, and computer readable recording medium having storage control program stored therein

When taking a back up of data stored on a disk in a redundant array of inexpensive disks (RAID) device to a plurality of tape devices, writing of the data is first started on all the tape devices. Once writing of the data is completed on the tape device having the highest data writing speed, writing of the data on other tape devices is stopped, and the data is set as clearing target data to be cleared from the disk of the RAID device. The data stored on the tape device, which has the highest data writing speed, is backed up to the other tape devices at a later timing.
