>  Error writing file /adsm01/dbvol2.dsm, errno = 27

This is the common error:

EFBIG           27      File too large.
                        Most commonly due to your Unix "filesize" limit
                        prohibiting writing a file that large.  Do
                        'limit filesize' to check.  If that value is too small,
                        try 'unlimit filesize'.  If that doesn't boost the
                        value, you need to change the limit value that the
                        operating system imposes upon you (in AIX, change
                        /etc/security/limits).
                        Can be caused by the JFS file system not configured to
                        allow "large files" (greater than 2 GB), per Large File
                        Enabled.  Do 'lsfs -q' and look for the "bf" value: if
                        "false", not in effect.
