Method, application system and memory device for managing application configuration information

Abstract

The invention provides a method for managing application configuration information, an application system and a storage device, is applied to a storage device which creates a logic resource application expansion region in advance, and stores a mapping relation between the logic resource application expansion region and the corresponding physical resource. The method comprises the following steps:the logic resource application expansion region of the storage device is accessed when an application system executes an application program; the storage device stores the application configuration information generated by the application system on the corresponding physical resource of the logic resource application expansion region according to the mapping relation between the logic resource application expansion region and the corresponding physical resource. The method, the application system and the storage device can help effectively avoid the problem that operation of the original application programs can not be recovered after the fault occurrence and recovery of the system or the storage device.

Description

Technical field [0001] The invention involves computer communication technology, and specially involves a method, application system and storage device in the field of computer network storage. Background technique [0002] In the field of network storage, storage devices generally include storage controllers or storage controllers and disk arrays or other components.In terms of location relationship, the front end of the storage device communicates with multiple hosts in the network through the network interface (FC interface or Ethernet interface) to provide them with storage services.In terms of storage applications, in order to block the physical differences of different storage media, providing a unified, robust and flexible management storage space to users of the storage medium, and the industry proposes a plan for virtualization of the storage medium.The virtualization of the storage medium is to map the access of logical resources to the access to physical resources by s...

Problems solved by technology

[0004]Because the application configuration information in the prior art is stored in the application system, if the application system fails, the application configuration information will be lost, although the logical resources of the storage device The data area can still be accessed, but the loss of application configuration information will make the operation of the application program irrecoverable; if the storage device fails and the physical resources are moved to another storage device, the application configuration information is associated with the original storage device Yes, that is, the source device or the destination device is the original storage device, and the application system cannot re-associate the original application configuration information with the transferred storage device, so the operation of the application program cannot be restored
