Static LDSs are defined using a standard naming convention of prefix.VVE.LDSnnnnn, where prefix is a DSN prefix defined to CA Vtape during the Customization Process and nnnnn is a sequence number.
Static LDSs are all 40 MB, 80 MB, or 200 MB depending on the 400 MB, 800 MB, or 2000 MB, Virtual Volume size chosen during the Customization Process. The Customization Process generates the JCL required to define and format the appropriately sized LDSs based on the chosen Virtual Volume size.
Ten LDSs are used to support a Virtual Volume mount request. After the application data set on the Virtual Volume is closed and the Virtual Volume is dismounted, unused LDSs are released for use with other Virtual Volume mount requests.
Any subsequent opening of the Virtual Volume causes the originally used LDSs to be opened, plus enough free LDSs to restore the total LDS count back to 10. This allows any modifying process to use the full 400 MB, 800 MB, or 2000 MB Virtual Volume capacity.
