Impact and Restrictions
This section describes the restrictions on the use of SmartMigration.
Application Restrictions
- Some parameters of storage systems supported by SmartMigration are subject to storage system specifications such as the maximum number of LUNs that can be configured for migration. For detailed specifications, refer to the Specifications Query Assistant (http://support-it.huawei.com/spec/#/home).
- The source and target LUN cannot be faulty.
- The capacity of the target LUN must not be smaller than that of the source LUN.
- Any LUN that has been mapped to an application server cannot be used as the target LUN of a SmartMigration task.
- The implementation of a SmartMigration task for heterogeneous storage systems depends on the LUN takeover function provided by SmartVirtualization.
Compatibility
When using SmartMigration, ensure that the host operating system, multipathing software, and the remote storage system are compatible with each other. You can query the compatibility using the Huawei Storage Interoperability Navigator.
