Why is a destination volume on SVM-DR smaller than its source volume?
Applies to
- ONTAP 9.4+
- SVM-DR
Answer
- In ONTAP 9.4 and later, XDP replaces DP as the default relationship type for SVM-DR.
- Type XDP SVM DR relationships separate both source and destination volumes size into two separate Entities.
- Due to this, when source volume size increases, destination volume size remain the same, unless auto size feature activates.
- By default, data protection volumes are set to the
grow_shrinkautosize mode, which enables the volume to grow or shrink in response to the amount of used space. - If volume autosize is not enabled for the snapmirror destination, consider enabling it and setting it to grow_shrink.
