Tim, As others have stated, the easiest way to change the expiration date of an active tape is simply use the ISPF interface or the old TIQ online interface; or even the Vantage/GMI GUI interface (Graphical User Interface). Or, if you want to do it with a batch job you could use TMSUPDTE to change the EXPDT value.
However, if you want to change via OPEN processing you can INCREASE the EXPDT value by either DISP=OLD (re-create processing, the entire dataset needs to be re-written) or DISP=MOD processing (add an additional record to the file). I haven't tried doing a DISP=MOD with IEBGENER where the SYSUT1 DD statement is DD DUMMY. It should still go through OPEN processing on the SYSUT2, in which case if the JCL specified EXPDT value is HIGHER then what is currently on the tape the existing tape's expiration date will be increased. This will NOT work however to decrease the expiration date, only to increase the expiration date.

When running with CA-1 active, is it possible to reset the expiration date of an existing tape dataset via the EXPDT= parameter in JCL? Some of us thought that at one time it was possible, at least for single-dataset volumes... but others don't. The only thing I could think of would be to rewrite the dataset with DISP=OLD and a new EXPDT= but I can't see that you could do it without recreating the dataset - for example, by reading it and coding EXPDT= in the JCL.
