What you can do if initialization fails or is interrupted
When an initial SnapMirror transfer fails, you can resume the transfer by re-entering the snapmirror initialize command if all the following conditions are satisfied.
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 can start the initial SnapMirror transfer again, instead of resuming the transfer.
SnapMirror does not automatically retry to initialize a destination.
