RE: New shared memory segments,while performing a backup with ontape. Why?
Posted in 1997
One other issue that I have run into is that the docs are WRONG. The engine will
only use 1 (one) temp dbspace during the archive with ontape. It appears to pick the
temp space with the most room, but when that fills, the archive crashes. If you have
a data dbspace that has more space, consider setting the DBSPACETEMP variable
at the O/S just prior to running the ontape session.

I'm on 7.2x but I think this applies to 7.1x also. The ISAM error: no
free disk space is probably due to DBSPACETEMP being filled up.
Ontape creates temp tables for each dbspace that it is backing up. If
you have heavy system activity during the backup you will most likely
blow out your temp dbspaces, if they are too small.
See the ontape chapter in the "Archive & Backup Guide" for a more
detailed explaination.
