We register a SQL instance using a server name and port number. In the Log Shipping Wizard, we use the SQL instance a subscriber in a log shipping plan. However, we get an error on “Subscribers” page when "next" is clicked. Note that the port number is not part of the SQL instance name in the “Specify Subscribers” field on the "Subscribers" page.
Software Defect. This issue is being tracked as LS-897: "Log shipping wizard does not use the port number of a registered SQL instance"
WORKAROUND 1
WORKAROUND 2
Create an alias with port number in the name.
STATUS
Waiting for fix in a future release of LiteSpeed.
