Hello and welcome to the forum,
restore many datasets(with different Serial number) from one specific tape
How are there multiple serial numbers for one specific tape.
You need to re-post your request so that the question represents something that is possible.
If you are doing some amount of processing using a single tape volume as input, suggest you specify RETAIN in the jcl. If you are not familiar with RETAIN, there is a link to "IBM Manuals" at the top of the page and one of the manuals listed is the JCL Language Reference manual.
