Each CA Vtape subsystem that is started will dynamically define a work data set for each Virtual Device that is defined in the OSDRIVES member. These data sets will have names of prefix.VVE.Ddevnum.sysname. Where prefix is the DSN prefix defined for CA Vtape use, devnum is the device number, and sysname is the system name. After defined by the first startup, these data sets are reused by subsequent starts unless they are deleted. Each device work data set is a VSAM linear data set 180 tracks in size.
If you will be starting CA Vtape on two systems and starting two instances of CA Vtape on one of those systems, then there will be three active CA Vtape subsystems. If each CA Vtape subsystem has 16 Virtual Devices, then 48 Virtual Device work data sets will be defined.
