The parmlib is a partitioned data set with fixed or fixed block 80 byte logical records: DCB=(RECFM=FB,LRECL=80,BLKSIZE=6400,DSORG=PO). It contains one or more members that contain CA Vtape parameters known as attributes. Related attributes are grouped into sections within a parmlib member.
Sample parmlib members containing the recommended settings for the CA Vtape attributes can be found in the HLQ.CCUUPARM library. The members are as follows:
Parmlib member directory, startup options, and dynamic options.
Virtual tape control unit and drive definitions. Optional CHPID device list
Group definitions and policies applied to the Virtual Volumes.
Tape mount intercept filter lists.
Volume pools and VOLSER ranges. Optional Virtual Volume Size.
Startup commands.
Shutdown commands.
These members together comprise one complete set of all the attributes used by CA Vtape. Each member contains one or more sections containing information used by CA Vtape at startup, shutdown, or during normal operations. This information is split into multiple members to make management and maintenance easier. If desired, you can combine one or more members or all members into a single member.
