Installation Considerations

The PROFILE EXEC for the CA Dynam/T Service Machine and user machines,

which will interface with the tape library via the DYNCAT utility, must have

access to the CSL Library, FSMPPSI. This library contains all of the CSL

routines for the Tape Library. The Disk containing this library (FSMPPSI

CSLLIB) must be linked and accessed to the machine.

Once these steps are completed, the interface can be activated.

Scratch Volume Mounts

For any scratch request for which a cartridge is suitable for allocation,

CA Dynam/T requests a scratch volume from the Tape Library, should an AVR

scan not locate a suitable volume. The default scratch pool used for allocation

is SCRATCH0, unless ECFLAG=02 is set in DTPARMS, in which case the scratch

pool is taken from the ownerid field of the data set definition. The first

character of the ownerid is the library id, defined in the system profile. The

second character is the scratch pool id.

Once a volume is mounted, it is validated against the CA Dynam/T catalog to

ensure it is a valid scratch volume, and if ownerid checking is enabled

(OWNCHK=YES), the ownerid is checked. If the volume fails validation, it is

rejected, unloaded, and returned to scratch status in the tape library. A new

volume is then selected. Once a valid scratch volume is found, it is attached to

the requesting user.

Specific Volume Mounts

For a request for a specific volume (input or output), CA Dynam/T VM queries

the IBM Tape Library to determine if the volume resides there. If so,

CA Dynam/T will request the volume to be mounted on an available drive,

determined by CA Dynam/T.

Volume Dismounts

Whenever a volume is unloaded, it is automatically removed from the drive by

the IBM Tape Library and returned to its storage cell.
