i would like to know the meaning of vol=(,,,15) with a System-Managed DASD Data Sets.
In the documentaation, there i :
Volume Count for System-Managed DASD Data Sets: You cannot specify a volume count for an existing system-managed DASD data set. (If you do, the system will ignore it.) When you create a new system-managed DASD data set, the volume count defined in the data class may be overridden by using the volume-count subparameter. However, if the volume-count subparameter specifies a value greater then 59, the system will set the volume count to a maximum of 59. The maximum volume count for a VSAM or System-Managed DASD data set is 59.
It is not GUARANTEED_SPACE. So i would like how will be allocated this dataset for example :
vol=(,,,15) is for the secondary space or the primary space ?
I there no VOL=(,,,15) specified either in the JCL, either in the dataclass, what is the default ?
Thank's for your help.
