Abstract

The invention provides a storage device data online migration method and system, a terminal and a storage medium. The storage device data online migration method comprises the steps: backing up back-end storage data of a to-be-migrated operating system; unbinding the volume of the to-be-migrated operating system from an original storage device by setting an FC port of the original storage device,and mapping the volume of the to-be-migrated operating system to a target storage device; mapping the volume migrated to the target storage device to an operating system of the target storage device by scanning the external storage; transferring the multi-path software of the operating system to be migrated and configuring the operating system of the target storage device; and migrating the backupdata from the original storage device to the target storage device. According to the method, online migration of the data between the storage devices can be realized, downtime in the data migration process can be avoided, and data loss is avoided.

Description

technical field [0001] The invention relates to the technical field of storage management, in particular to a storage device data online migration method, system, terminal and storage medium. Background technique [0002] The risk involved in data migration is very high, especially for old storage, such as the old storage more than 10 years ago, which has poor performance, poor stability, and poor scalability. The maximum number of supported hard disks does not exceed 500. The upper-layer applications all use Oracle rac or Mysql cluster applications. Therefore, the expansion of the old data center requires the use of new storage, and the deployment of new storage requires the seamless migration of data from the old storage device to the new storage. This requires careful deployment and analysis of the migration work to prevent the occurrence of Any failures and downtime, as well as any failures and downtime during the migration need to be dealt with in a timely manner to p...
