There is no mixture of drives in our library nor is there a mixture of generations of 3592 media.
There are only IBM3592-E06 (TS1130) and only long JB media.
Data is written in different forms, E05 and E06 alike.
There are no production problems arising from this configuration, only question is how to use most of it. I bet there is some way to tell if it is efmt3 or efmt2 a given tape is written with, perhaps using tapeutil.

Observe the TSM documentation, which says:
"Avoid specifying DRIVE when a mixture of drives is used within the same 
library."
and
"For optimal performance, do not mix generations of 3592 media in a single library. 
Media problems can result when different drive generations are mixed."

There is backward compatibility to E05 from E06. The new drives can read and 
write the old tapes.
Yes, but you are seeking to achieve specific results, where only specific 
definitions will guarantee such results.  Loose definitions can make for 
undesirable results, and problems.  You are already having problems telling the 
tapes apart.

I am using format=drive in my devclass, no problem reading E05 tapes. A filling 
E05 tape will be written in E05 format, a new one in E06 format.
But how to see which tape is written in E05 ? ( the written capacity is some 
hint, but on filling its difficult).

Would not your prior use of 3592-E05 have been with devclass Format 3592-2, and 
new use of 3592-E06 be with devclass Format 3592-3, in a recent TSM 
version/level supporting that specification?
