This is not exactly AIX limit, but JFS (1). AIX 5L with JFS2 supports up to
1 TB.
Try what if you restore not to file but to raw logical volume. AIX XCOFF
format promises up to 2^63 bytes file addressing limit. I cannot promise it
would help but you do not have too much options which can solve the
problem. And this may be workaround without upgrade. So give it a shot.

Subject:        How to extract a db2-backup > 64Gb

Hi,

To restore our db2-db to another RS6000 (without TSM) I want to
extract a DB2/TSM backup file from TSM to a filesystem,
compress it, send to the other machine and restore it. With a
backup to disk that works ok, because the db2 backup command
splits up the file in parts of 64GB (an AIX-limit) but the db2adutl
extract command tries to write beyoud the 64Gb-limit and then fails
with the message 'File write failed'.
Does anybody know how to handle this?
DB2 v6.1 (FP8)
TSM v4.1
AIX 4.3.3

Thanks
Bert
