Volume rehost enables you to migrate a transitioned volume from one SVM to another SVM without data copy. The rehost operation enables you to consolidate all volumes that have FC LUNs to a single SVM, thereby preserving the 7-Mode single-system image (SSI) semantics. You can also rehost transitioned NAS volumes.
Rehosting is a disruptive operation.
The following volume policies, policy rules, and configurations are lost from the source volume and must be manually reconfigured on the rehosted volume after the rehost operation:
|If you want to...||Run the following command...|
|Unmap the LUNs after rehosting||volume rehost -vserver source_svm -volume vol_name -destination-vserver destination_svm -force–unmap-luns true|
|Remap the LUNs to the same igroups after rehosting||volume rehost -vserver source_svm -volume vol_name -destination-vserver destination_svm -auto-remap-luns true|
You set the -relationship-info-only parameter to true so that the Snapshot copies are not deleted and only the source relationship information is removed.
