To reinitialize log shipping from the LiteSpeed Console.
Right-click the Subscriber database in the Monitoring tab and select Reinitialize.
NOTE: When you reinitialize log shipping, the plan status is updated only after usual backup transaction log, copy and restore jobs are completed. You can also re-initialize log shipping using stored procedures (see example below). These steps are documented in the LiteSpeed Configure Log Shipping User Guide. Also, available in the LiteSpeed Help File - press F1 in the LiteSpeed Console.
Reinitialize Log Shipping after finding the Log Shipping Plan ID.
