If an initial SnapMirror transfer fails, you can resume the transfer by re-entering the snapmirror initialize command, under certain conditions.
If the following conditions are met, you can resume the initialization of a SnapMirror relationship:
- The value for restart mode in the /etc/snapmirror.conf file is set to always or is set to the default, and the next scheduled update has not begun.
- The output of the snapmirror status command displays that the process has a restart checkpoint.
- The Snapshot copy used for the initial SnapMirror transfer still exists.
- The disk geometry has not changed.
Note: If these conditions are not satisfied, you cannot resume the initial transfer. You need to start the initial SnapMirror transfer again.
SnapMirror does not automatically retry to initialize a destination.
