After disconnecting the multipath connection between the external storage system and the busi-
ness server, use RAID Migration to read data from the migration target volume in the external stor-
age system and write data to the migration destination volume in the local storage system.
Data consistency is ensured because the data remains in the migration source volume for consoli-
dated management during the data migration.
•
Only FC ports (connected in the FC-Initiator mode) are supported for connections with exter-
nal storage systems.
•
The Non-disruptive Storage Migration License must be registered to use this function.
For details on the license, contact your sales representative.
•
Only data migrations from the external storage system to the local storage system is suppor-
ted.
Data migrations from the local storage system to the external storage system or between ex-
ternal storage systems is not supported.
•
The local storage system volume returns the same information as the External Volume even af-
ter a migration is completed.
•
Do not set the copy operation suppression, the cache parameters, and the Volume QoS for the
External Volume.
•
The functions that can be used for the External Volumes are delete, rename, and RAID migra-
tion. Other functions cannot be used until the data migration is successfully completed.
•
Migration destination volumes in the local storage cannot be used for Storage Cluster even af-
ter the migration is completed.
•
Make sure to delete the Non-disruptive Storage Migration License after the Non-disruptive
Storage Migration is complete.
