Hi,
My question was answered by Steve Hancock USG <hancock_at_decatl.alf.dec.com>.
Thanks Steve. He writes:
The answer to your question is that when you use the showfile command
without the '-x' switch you are only looking at the location of the
metadata for the file which cannot be migrated with the migrate command.
Try looking at the extent map which shows where the data blocks for
you files reside (assuming the file is larger than a full-sized block
or 8k) by using the "showfile -x" command. I think you's find this
works better.
and indeed, this works.
