Hallo All, we are working since two weeks(or more) on a PMR that mmbackup has problems with the MC Class in TSM. The result is that we have defined a version exist of 5. But with each run, the policy engine generate a expire list (where the mentioned files already selected) and at the end we see only (in every case) 2 Backup versions of a file. We are at: GPFS 5.0.1.1 TSM-Server 8.1.1.0 TSM-Client 7.1.6.2
After some testing we found the reason: Our mmbackup Test is performed with vi , to change a files content and restart the next mmbackup testcycle. The Problem that we found here with the defaults in vi (set backupcopy=no, attention if no a backupcopy are generatetd) There are after each test (change of the content) the file became every time a new inode number. This behavior is the reason why the shadowfile think(or the policyengine) the old file is never existent And generate an delete request in the expire policy files for dsmc (correct me if I wrong here) . Ok vi is not the problem but we had also Applications that had the same dataset handling (as ex. SAS) At SAS the data file will updated with a xx.data.new file and after the close the xx.data.new will be renamed to the original name xx.data again. And the miss interpretation of different inodes happen again. The question now are there code in the mmbackup or in gpfs for the shadow file to check or ignore the inode change for the same file.
