Relink SnapVX snapshot
Description
An existing snapshot can be unlinked and relinked to a different snapshot from the same source device. To relink a snapshot, a link must already exist on at least one of the targets. Relinking can also be used on the same snapshot, which has the effect of refreshing the point-in-time copy on the link target if it has been modified by host writes.
NOTE:An expired secure or regular snapshot cannot be relinked.
Options
- -lnsg
- Specifies a SG name for target devices.
- -generation
- Specifies the generation number on the source SG.
- -snapid
- Specifies the snapsetID on the source SG.
- -copy
- Specifies copy mode for relink operation which performs a background copy to the target device. If the relink is in Copy mode, the copy is differential between the original linked snapshot and the newly linked snapshot.
- -remote
- Data is propagated to the remote mirror of the RDF device. Not allowed on a NoCopy linked target.
- -exact
- Pairs source and link devices by their ordinal positions in the selection. If not set, pairs source and link devices by best match.
Examples
To relink (in Copy mode) to generation 6 of the 600am snapshot, enter:
symsnapvx -sid 001 -sg StorageGroup1 -lnsg StorageGroup2 -snapshot_name 600am -gen 6 relink -copy
