SnapMirror can migrate data between volumes and redirect NFS clients to the new volume without rebooting the storage system or remounting to volume on NFS clients.
Considerations
The migration must be run on two volumes which are currently the source volume and destination volume in a
SnapMirror relationship. Once you start the migration process,
SnapMirror:
- Performs a SnapMirror incremental transfer to the destination volume.
- Stops NFS and CIFS services on the entire storage system with the source volume.
- Migrates NFS file handles to the destination volume.
- Makes the source volume restricted.
- Makes the destination volume read-write.
Step
- Enter the following command:snapmirror migrate [srcsystem:]srcvolume [dstsystem:]dstvolume
srcsystem is the source system.
srcvolume is the source volume.
dstsystem is the destination system.
dstvolume is the destination volume.
