This message can occur when an IDMS file spans multiple physical volumes.
From the Database Administration Guide, Chapter 17 "Allocating and Formatting Files", sub-section "Creating Disk Files" (page 553 in the r17.0 Sp1 manual set):
CA IDMS does not support files that span multiple physical volumes. If an area is too large to reside on a single volume, it must be mapped to multiple files, each residing on a single physical volume.
In this particular case, IDMSDBAN did not report this situation with an error.
IDMSDBAN does not access the database through the DBMS. The DBMS builds its own I/O commands and is not designed to handle multiple extents. IDMSDBAN uses a standard opsys sequential read and as a result is not impacted by the multiple extent restriction.
