JES3 Requirements

CA Vtape can be installed in a JES3 environment, but the Virtual Devices defined for CA Vtape use cannot be placed under JES3 allocation control. To accomplish this, the following conditions must be met:

The Virtual Devices are not defined in the JES3 Initialization Statements or INISH deck. Allocation will be handled directly by the operating system and treated like JES2 allocations.
A unique esoteric is defined to contain the Virtual Devices.
The Virtual Devices are defined as a device type that would not include them in a generic that includes devices controlled by JES3. For example, if 3490 devices are defined to the system and under JES3 control, the CA Vtape devices are defined as 3480 devices. If 3490 and 3480 devices are defined to the system and under JES3 control, then all of the 3490 or all of the 3480 devices are removed from JES3 control and the CA Vtape Virtual Devices are defined as the removed device type.
High Water Mark (HWSNAME,TYPE=) and SETNAME statements included in the JES3 INISH deck do not refer to the esoteric or generic used by the Virtual Devices.
If an existing esoteric or generic was reused for the Virtual Devices, any references to them in the JES3 Initialization Statements are removed.
