Hi all,

In the past I've used the 'rec=5' at 3am and 'rec=100' at 11am style
of space reclamation management, however I find that the same does
not work for migration.


I have a customer who wishes to migrate data from a disk pool (at a
tape-less
site) to a central disk-pool for later migration to tape and copypools etc.

This is a fairly new setup, and we find that migration tends to completely
bog
down the network link.

At first glance, there appears to be two options:
(1) turn off migration during business hours and
(2) link bandwidth managment.


I have tried changing the migration thresholds however the migration
won't stop.

If we cancel the migration process, the job transaction rolls-back so far
most
of the migration effort is lost.

Does anyone have any suggestions?   Is there an effective method for
controlling migration processes?

Can you recommend a method for throttling the bandwidth usage?
