You have to check the migcontinue parameter. If it is at YES (the
default) it will not take into account the migdelay parameter when doing
migrations

I have that setup on one of my pools.
Hi and lo are set to 0 and never change, and it only migrates data over
the migdelay value...

 Could someone in the group please explain to me how migdelay works. I
am wanting to setup a disk pool to migrate data 90 days old. I was under
the impression that when data was 90 days or older it would
automatically migrate to next pool. I was told that one thing that would
happen is, as soon as data became 90 days old, it could migrate at
anytime during the night, so I wanted to control that, so I setup a job
to set migdelay 90 in the mornings and then set it back a few hours
later to 0. So far, I haven't seen it migrate anything off. I was then
told "NO" you have to set you hi/lo thresholds down to kick migration
off but then that gets your oldest data first but it doesn't stop there
it will keep migrating until your low threshold is met so it could
migrate data newer than 90 days. Clear as mud? This is our 3rd tsm
server, but a new one. I am on AIX 5.3TL4 TSM 5.3.3.1. Sorry if this has
already been covered at some point by this group. Thanks in
advance.....Rod.
