z/OS R7:
Extend Tape Table of Contents (TTOC) records to raise the DFSMShsm
limit on the number of data sets per tape to support more than
330,000 data sets per volume. This can provide better DFSMShsm
exploitation of new larger capacity tape cartridges by allowing
over 1,000,000 data sets per migration or backup tape volume.
( Note: Other factors also affect the number of data sets that can
be stored on a tape.)
(BTW, 255? How long ago was the limit 255?)
John,
Thanks.
I remember crawling one time through HSM CDS's and I thought that
they had a 1 byte field (255) . This was quite some time ago (maybe
10 years). I could be wrong but thought at the time this was awfully
small. Since that wasn't the issue I was looking at I put the thought
aside and continued looking for another field.
