For an initial, baseline transfer for a SnapMirror relationship, you might want to perform the transfer using a tape. After copying the base data to the tape, you need to copy the data from the tape to the intended destination, and initialize the destination.
- Create a volume on the SnapMirror destination system.
For more information about how to create a volume, see the Data ONTAP Storage Management Guide for 7-Mode.
- Put the volume in the restricted state. For more information about how to restrict a volume, see the Data ONTAP Storage Management Guide for 7-Mode.
- Load the tape (made with smtape backup) into the destination system’s local tape device.
- Start the initialization by using the smtape restore command on the destination system.
- If the system prompts you for another tape, add the next tape to the drive and continue the initialization by using the smtape continue command.
- Repeat the previous step until the volume is completely copied from the tape.
- Optional: You can update the data online manually with the following command: snapmirror update [-k n] -S source_system:source_volume [dest_system:]dest_volume
sets the maximum transfer speed to n
kilobytes per second. This option has the same effect as the kbs
argument in the /etc/snapmirror.conf
-S source_system:source_volume specifies the source system and volume for the migration. source_volume is the volume you want to copy.
dest_system is the name of the destination system.
dest_volume is the destination volume.
Note: Alternatively, you can update the baseline transfer automatically with the schedule you set in the /etc/snapmirror.conf file.
