How to save 'migration candidate filelists' generated by GPFS in /tmp directory?

Hi all,

do you know if there is a way to save (in a different directory) all migration candidate file lists TEMPORARY generated by GPFS!?
I need to know when a file has been migrated consulting mmpolicy.ix.xxxxxx file in /tmp directory (or in other directory specified by user).

Can you help me!?

Thanks a lot,
Mauro Tridici
