Abstract

The embodiment of the invention provides a data storage method, a storage array and a host computer server, relates to the technical field of storage, and solves the problem of data corruption or service interruption caused by the fact that the change of a mapping relation between a logical disk in the storage array and a virtual disk in the host computer server cannot be updated in real time on the host computer server after the change of the mapping relation cannot be solved completely in the prior art. The method comprises the following steps: receiving an I / O request sent by the host computer server by the storage array, wherein the I / O request is carried with a first token; matching the first token with a plurality of current tokens by the storage array; if one current token same as the first token exists in the current tokens, processing the I / O request through the logical disk corresponding to the current token same as the first token by the storage array, and sending a message that the I / O request is successfully processed to the host computer server; and if the one current token same as the first token does not exist in the current tokens, sending a message that the I / O request is unsuccessfully processed to the host computer server by the storage array.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a data storage method, a storage array and a host server. Background technique [0002] Configuring the mapping relationship between the logical disks in the storage array and the virtual disks in the host server is a basic operation for running host services using storage resources in a storage area network (English: storage area network, abbreviated as SAN). In the actual production and service environment, business requirements will continue to change, and the mapping relationship needs to be maintained, so changing the mapping relationship is one of the common operations. [0003] However, in the prior art, after the above-mentioned mapping is changed, the change of the mapping relationship cannot be updated in real time on the host server, so that when the host server sends an input / output (English: input / output, abbreviation: I / O) request to the storage array data corrupti...
