1. Function
Non-disruptive Storage Migration
Data consistency is ensured because the data remains in the migration source volume for consolidated manage-
ment during the data migration.
Only FC ports (connected in the FC-Initiator mode) are supported for connections with external storage sys-
•
tems.
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 supported.
Data migrations from the local storage system to the external storage system or between external storage
systems is not supported.
The local storage system volume returns the same information as the External Volume even after a migra-
•
tion is completed.
Do not set the copy operation suppression, the cache parameters, and the Volume QoS for the External Vol-
•
ume.
The functions that can be used for the External Volumes are delete, rename, and RAID migration. 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 after the migra-
•
tion is completed.
Make sure to delete the Non-disruptive Storage Migration License after the Non-disruptive Storage Migra-
•
tion is complete.
