Answer
- From the destination cluster, use the
SnapMirror show
command with the-snapshot-checkpoint
parameter to view the status of the baseline transfer and the restart checkpoint.
Example
cluster2::> snapmirror show -destination-path dest_vserver:vol3 -fields snapshot-checkpoint source-path destination-path snapshot-checkpoint -------------------- ---------------- ------------------- src_system:vol3 dest_vserver:vol3 50MB
- If the SnapMirror checkpoint exists, use the
SnapMirror initialize
command to resume the baseline transfer.
Example
cluster2::> snapmirror initialize -destination-path dest_vserver:vol3
However, at times the restartable checkpoint can be deleted under one of the below criterions
- If volume is marked offline and deleted by any means.
- If a '
SnapMirror break'
command is issued against the relationship. - If a SnapMirror with the hard abort switch is issued. Performing a hard abort deletes the checkpoint.
If the restartable checkpoint is deleted , restarting the transfer will start from the beginning and not from the checkpoint.
