Since initializing a DASD volume includes assigning the volume serial (usually), EVERYBODY I know of initializes them one at a time. You might set up a batch of them in a job and run several jobs to initialize 200 volumes, but you won't be initializing 200 volumes to -- for example -- DASD01 volume serial (or whatever).

Thanks :) !!
Imagine that you want to initialize 3000 DASD device !!! this process needs long time to complete.
Is there any way to save time ?????

Have you looked at the manual for ICKDSF to find out what can and cannot be done with DASD initialization? If not, you should read this manual thoroughly.

Few -- if any -- sites would initialize 3000 (or even 200) DASD volumes at one time. Usually DASD volumes are initialized when they are being prepared for use, and that rarely involves more than 10 or 20 volumes -- many times only 1 or 2 volumes are being added for an application's use. You have to know if each volume is SMS-managed or not, you have to know the volume serial(s), and beyond initialization there is often other work to be done (such as adding the volume(s) to the appropriate storage group for SMS).

Assuming that all of the parameters for each volume are the same apart from the device address and the volser, you could perhaps write a utility in a language of your choice (Rexx would be simple enough) to generate the JCL for a batch job which then could be submitted. It would be simple enough to increment the volser number by 1 for each step, and if the device numbers are consecutive then this shouldn't be too tricky either.

As others have said, an unusual requirement though. You'd have to consider if the time spent writing the code to generate the JCL was worth it compared to doing each individually.
