How we can know the auxiliary numbers free and used in the VMF file?
There are 2 ways to get the number of free auxiliary.
1. Run PGM=TLMSVMFU to backup of the VMF file to get the following report:
Dump Volume Master Report - TLMS048
TOTAL INPUT RECORDS READ...................615
TOTAL CONTROL RECORDS WRITTEN................1
TOTAL SEGMENT RECORDS WRITTEN................1
TOTAL BASE RECORDS WRITTEN.................461
TOTAL MVL RECORDS WRITTEN....................0
TOTAL MDS RECORDS WRITTEN...................12
TOTAL AUXILIARY RECORDS WRITTEN.............90
TOTAL MESSAGE RECORDS WRITTEN...............50
TOTAL RECORDS WRITTEN......................615
TOTAL ORPHANED MVL RECORDS...................0
TOTAL ORPHANED MDS RECORDS...................0
TOTAL ORPHANED VSN RECORDS...................0
TOTAL WARNING MESSAGES.......................0
Where
TOTAL INPUT RECORDS READ
Total records contained in the VMF backup (control, segment, base, MVL, MDS, message and auxiliary).
TOTAL MDS RECORDS WRITTEN
Number of auxiliary records used to chain multi-data set volumes.
TOTAL AUXILIARY RECORDS WRITTEN
Number of unused auxiliary records left in VMF for chaining.
TOTAL RECORDS WRITTEN
Total of all records written to the VMF (control, segment, base, MVL, MDS, message and auxiliary).
OR
2. Run the TLMSVMFV to verify the VMF using the same technique used by TLMSVMFU for the VMF utilities and get the following report:
