Abstract

The invention relates to a data storage technique, and discloses a method and device for carrying out charged uninstallation and installation of a hard disk for a digital video recorder. In the invention, when the hard disk is required to be pulled out, relevant tasks are informed of stopping using the hard disk, and after all the relevant tasks stop using the hard disk, relevant information in a hard disk management system is updated, so that the seamless transfer of services can be guaranteed when the hard disk is replaced, and service cannot be lost; when an available hard disk which is not listed in the hard disk management system is detected, relevant tasks are informed of adding the hard disk, so that a DVR (digital video record) can normally recognize the new plugged hard disk and put the hard disk into operation without affecting current various tasks; and when the hard disk is uninstalled, the digital video record is not required to be powered off, and the video recording is not required to be interrupted, thereby maintaining the consistency of the video recording.

Description

technical field [0001] The invention relates to the data storage technology, in particular to the technology of live unloading and installing the hard disk of a digital hard disk video recorder. Background technique [0002] Hot-plugging (hot-plugging or Hot Swap) is hot-plugging. The hot-plugging function allows users to take out and replace damaged hard drives, power supplies or boards and other components without shutting down the system or cutting off the power supply, thereby improving It improves the system's ability to recover from disasters in a timely manner, expandability and flexibility, etc. For example, some disk mirroring systems for high-end applications can provide disk hot-swappable functions. The specific academic terms are: hot replacement (Hot replacement), hot addition (Hot expansion) and hot upgrade (Hot upgrade). [0003] Hot plug first appeared in the server field, and it was proposed to improve the usability of the server. Generally, the computers w...
