Thanks Brian
LDSF is a new name for LDEV....I guess it's an upgrade <G>.
And we do have maxldev set to 4096 and we are no where near that many, I think.
Doing a query ldev l001-lfff shows we are well under the 4096 mark.
But kind of interesting reading the output.

LDSF is Logical Device Support Facility.
The default maximum number of logical devices for the system 4096. Use
SET MAXLDEV to change it. See "CP Programming Services" for more
information (Appendix E is a good place to start).
