Hi,

See http://people.bu.edu/rbs/ADSM.funcdir, keyword: MIGRATION
                                        Occurs with one process per node
                                        (regardless of the MIGPRocess value),
                                        choosing the node with the largest
                                        amount of data in the storage pool and
                                        moving *all* of that node's data before
                                        embarking upon the same processing for
                                        other nodes - or before again checking
                                        the LOwmig value.
When you change the LOWMIG value TSM waits till it has moved *all* files of the
node it is currently working on.
So this might take some time if you have nodes with many, many files.

Betreff: [ADSM-L] migration doesn't seem to be ending


Hello all,

After viewing our Backup Disk Pool,  I noticed that migration
doesn't seem to be stopping. The below percentages don't seem
right since I have the following settings. Anyone else see
this as odd or am I missing something?  If so what could be
causing this?

Thanks for any suggestions, help!
