We have recently installed an NSM C01 with an IBM 3584 LTO library. TSM level is V4.1 We use a DISKPOOL and a TAPEPOOL. We defined a MAXSIZE=1G for the DISKPOOL. TAPEPOOL is the nextpool of the DISKPOOL. When we are backing up files we notice that all files smaller than 1 GB are not being backed up at all. If we remove the MAXSIZE parameter, all files are backed up. Any explanation for this? or is this a bug?
