We are running the mmbackup on an AIX system <br>
oslevel -s<br>
6100-07-10-1415<br>
Current GPFS build: "4.1.0.8 ".<br>
<br>
So we only use one node for the policy run.<br>

<tt>That seems rather slow. What version of GPFS are you running? How many nodes are you using? Are you using a "-g global shared directory"?</tt><br>
<br>
<tt>The original mmapplypolicy code was targeted to a single node, so by default it still runs on a single node and you have to specify -N to run it in parallel. When you run multi-node there is a "-g" option that defines a global shared directory that must
be visible to all nodes specified in the -N list. Using "-g" with "-N" enables a scale-out parallel algorithm that substantially reduces the time for candidate selection.</tt><br>
