MOVEMENT
VERIFY
/*
The MOVEMENT function activates the vault movement. The VERIFY function
gets a slot number for all volumes whose vault is not rotated and for whose
vault location slot support is defined. You can run this first with the DUMMY
option to avoid CA Dynam Catalog update.
For more information about these functions, see TDYNVLT Commands.
Running TDYNVLT
Run TDYNVLT daily or weekly, depending on how often you transfer tapes from
one location to another. By definition, vault location A is the main tape library.
The DYNCAT SCRATCH function will scratch expired versions only if they
currently reside in location A. Therefore, if you run both programs each day,
run TDYNVLT before DYNCAT.
TDYNVLT has the following six phases of execution:
1. Gathers all vaults that will require an automatic verify
2. Collects vault location changes
3. Verifies, frees, and gets slot numbers; also updates the CA Dynam Catalog
4. Prints movement reports
5. Generates inventory reports
6. Prints the inventory reports
If TDYNVLT cancels for any reason during execution, run the DYNCAT BACKUP
function to verify the integrity of the Catalog: Vault movement information
may have been lost. (DYNCAT RESTORE is unnecessary if you are running
TDYNVLT with the DUMMY option, or if the CADT602I message has not been
issued.)
You can activate TDYNVLT functions with control statements. If you do not
submit any control statements, TDYNVLT will end normally unless TDYNVLT
detects that an automatic verify is required. In that case, TDYNVLT continues
as if the VERIFY control statement had been submitted.
