I had this problem with our first falconstor.   There was something wrong
with the compression chip and it was unable to read back the data it had
written.  Rebooting the falconstor would fix the problem temporarily, but
once the data was written when the chip was in a bad mood, it was
corrupted.
I would do spot checks of these volumes that exhibited the error by using
"Audit volume"  (I.E. find out which volume was mounted when you had the
error)

And despite the DD and Falconstor recommendation to only keep one pool and
let them handle replication, I still use TSM's backup-stg to handle
replication between multiple VTL's.  Saved my butt in this case!  I was
able to restore all the volumes from the copy pool.


Regards,
Shawn

Has any one seen the below error?  I have TMS 5.5.4 running on AIX 6.1
and no issue on all backups except backups pointed to data domain
storage pool. Recently when DBA  try to restore rman backup getting
message  ANS0322E (RC40) no text available for this return code. When I
check the TSM server side  see the below message. After the first
incident datadomain/emc swapped out the hardware but we are still
getting same error.
