<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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 <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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.

<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">After some testing we found the reason:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial",sans-serif">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.<o:p></o:p></span></p>
