But, there could be situations that the remote snap group at time T(x-n) may NOT be
available – could have been deleted by an automatic schedule. In this scenario, the system
will do one of the following operations:
•
First it will try to find matching most recent snap group across ACTIVE and
PASSIVE. If available, then the PASSIVE will be rolled back to the matching snap
group and replication will start from there.
•
If no matching snap groups present that is safe (out of disaster), then there is no way
the replication can continue with given parameters. In such scenarios, the PASSIVE
volume data will be wiped out and replication will start from the beginning.
