Configuring SmartMigration Between Storage Systems
To use SmartMigration between storage systems, you must first implement the LUN takeover function of SmartVirtualization. The LUN takeover function helps migrate service data smoothly from the source LUN to the target LUN to meet the requirement for storage system upgrade. This section describes the process for configuring SmartMigration between storage systems.
- Configuration Process
The process for configuring SmartMigration between storage systems comprises checking the license file, taking control of a LUN from a heterogeneous storage system, creating a SmartMigration task, and splitting a SmartMigration pair or splitting SmartMigration pairs concurrently. A flowchart is provided to guide you through the configuration process. - Checking the License File
A license file that grants the permission to use SmartMigration and SmartVirtualization must be available. Before configuring SmartMigration and SmartVirtualization, ensure that the license file in use grants the permission. - Taking Control of a LUN from a Heterogeneous Storage System
Implementation of SmartMigration between storage systems requires the LUN takeover function of SmartVirtualization. Before creating a SmartMigration task, let the local storage system take control of a LUN from a heterogeneous storage system. Then use the LUN as the source LUN of a SmartMigration task and migrate services from the heterogeneous storage system to the local storage system. - Creating a SmartMigration Task
SmartMigration achieves full replication of source LUN data to the target LUN. After the replication is complete, the target LUN takes over all services from the source LUN. - Splitting a SmartMigration Pair
A target LUN stores a point-in-time data duplicate of the source LUN only after the pair is split. The data duplicate can be used to recover the source LUN in the event that the source LUN is damaged. In addition, the data duplicate is accessible in scenarios such as application testing and data analysis. - Splitting Multiple SmartMigration Pairs Consistently
Consistency split means that multiple SmartMigration pairs are split at the same time, which ensures data consistency of the target LUN and does not affect the normal service running of the target LUN.
