Rehosting a volume from one SVM to another SVM

Volume rehost enables you to reassign NAS or SAN volumes from one storage virtual machine (SVM, formerly known as Vserver) to another SVM without requiring a SnapMirror copy. The volume rehost procedures depend upon the protocol type and the volume type. Volume rehost is a disruptive operation for data access and volume management.

Before you begin

Several conditions must be met before you can rehost a volume from one SVM to another:

  • The volume must be online.

  • Protocols: SAN or NAS

    For the NAS protocol, the volume must be unmounted.

  • If the volume is in a SnapMirror relationship, then the relationship must be either deleted or broken prior to volume rehost.

    You can resynchronize the SnapMirror relationship after the volume rehost operation.

  • Rehosting CIFS volumes
    You can rehost volumes that serve data over SMB protocol. After rehosting the CIFS volume, to continue accessing data over SMB protocol, you must manually configure policies and the associated rules.
  • Rehosting NFS volumes
    You can rehost volumes that serve data over NFS protocol. After rehosting the NFS volumes, to continue accessing data over NFS protocol, you must associate the volume with the export policy of the hosting SVM and manually configure policies and associated rules.
  • Rehosting SAN volumes
    You can rehost volumes that have mapped LUNs. After re-creating the initiator group (igroup) in the destination SVM, volume rehost can automatically remap the volume on the same SVM.
  • Rehosting volumes in a SnapMirror relationship
    You can rehost volumes in a SnapMirror relationship.
  • Features that do not support volume rehost
    There are certain features that do not support volume rehost.
