When I try to copy ZVA111 as other than the 1st tape, this tape is copied 
correctly. So, to resolve temporarily our problem we have prepared first tape 
which is everyday copied with error. Next tapes are copied correctly so in fact 
we have complete alternate copies. However, it isn't solution in general.
Duplex is good solution, but our alternate 3490 drives are manual and there is 
a problem with operators at night, when we make our HSM backups.

What happens if you try to copy ZVA111 as?

Why not just create the "copies" concurrently with the originals? i.e.
duplexing

This will a) eliminate the need for the tapecopy in the first place
          b) be sensitive to the length of either virtual or physical
media (the "shorter" one wins, be it virtual or
             physical

we have the following problem with HSM TAPECOPY. First time it appeared
after migration from 1.7 to 1.9. (In 1.7 everything was OK)

Each time during TAPECOPY BACK processing (from VTS  3490 virtual tape
to 3490 physical tapes), first tape copy finish with the following
error:

ARC0425I COPY OF ZVA111 FAILED - REASON=29            

In documentation I've found following explanation:

"During  processing  of  the  TAPECOPY command,  a  volume  to  be
copied  is  of 

a  different  length  than  the  volume  to which  it  is  to  be
copied  or  the  input 

and  output  tape  drives  use  a  different recording  technology.
DFSMShsm 

does  not  allow  a  TAPECOPY  from  an enhanced  capacity  tape
cartridge  to  a 

standard  capacity  cartridge,  nor  does it  allow  a  TAPECOPY  from
a  standard

capacity  cartridge  to  an  enhanced capacity  tape  cartridge..."
