CATVMFV - Verify the Volume Master File

Use the CATVMFV procedure to verify a VMF or backup of a VMF and produce the TLMS064 report.

TLMSVMFV is executed to verify the VMF using the same technique used by TLMSVMFU for the VMF utilities. The technique allows TLMSVMFV to verify VMF record chaining without "running the chains". This prevents I/O errors from bad chains and allows TLMSVMFV to continue verification of a chain after an error is detected. TLMSVMFV also finds orphaned records. Orphaned records are records which cannot be found by TLMS batch processing that starts with the beginning of a tape chain.

The scope of the verification and reporting is controlled by the following CATVMFV parameters:

DELAY

This parameter instructs TLMSVMFV to delay the verification of tape chains for the specified number of days. This prevents reporting of false errors for tapes which are being created while CATVMFV is running.

LEVEL

This parameter specifies the level of detail TLMSVMFV is to report. The LEVEL parameter can greatly reduce the size of the TLMS064 report. By default TLMSVMFV uses DELAY=3 and LEVEL=1. The report levels are:

• Level 1 is the default report level.
• Level 5 and above print orphans records. These are records which are not connected to valid TLMS chains. These records are lost during a VMF RESTORE.
• Level 9 is the most detailed report. Level 9 overrides the DELAY PARM. Level 9 can only be run against a VMF that has no activity.
