<font size=2 face="sans-serif">HI , </font><br><font size=2 face="sans-serif">first of all, given by the fact, that
the MetaData is stored in system pool .. system should be the "fastest"
pool / underlaying disks ... you have.. </font><br><font size=2 face="sans-serif">with a "slow" access to the
MD, access to data is very likely affected.. (except for cached data,
where MD is cached) </font><br><br><font size=2 face="sans-serif">in addition.. tell us, how "big"
your test files are ? .. you moved by mmapplypolicy </font><br><br><br><div><font size=2 face="sans-serif">Mit freundlichen Grüßen / Kind regards</font><br><br><font size=2 face="sans-serif"> <br>Olaf Weiser<br> <br>EMEA Storage Competence Center Mainz, German / IBM Systems, Storage Platform,<br>-------------------------------------------------------------------------------------------------------------------------------------------<br>IBM Deutschland<br>IBM Allee 1<br>71139 Ehningen<br>Phone: +49-170-579-44-66<br>E-Mail: olaf.weiser@de.ibm.com<br>-------------------------------------------------------------------------------------------------------------------------------------------<br>IBM Deutschland GmbH / Vorsitzender des Aufsichtsrats: Martin Jetter<br>Geschäftsführung: Martina Koederitz (Vorsitzende), Susanne Peter, Norbert

tiering and policies in general in SpecScale. I have a single filesystem
with two pools defined (system, GOLD). The GOLD pool is made up of
some faster disks than the system pool. The policy I’m trying to
get working is as follows</font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri">RULE 'go_gold'</font><br><font size=2 face="Calibri"> MIGRATE</font><br><font size=2 face="Calibri"> FROM POOL 'system'</font><br><font size=2 face="Calibri"> TO POOL 'GOLD'</font><br><font size=2 face="Calibri"> WHERE (LOWER(NAME)
LIKE '%.perf')</font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri">I’m simply trying to get the data to move
the NDS’s in GOLD pool.</font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri">When I do an mmapplypolicy, mmlsattr shows
that it’s now in the GOLD pool but when I do a mmdf the data shows 100%
free still. I tried a mmrestripefs as well and no change to the mmdf
output. Am I missing something here? Is this just normal behavior
and the blocks will get moved at some other time? I guess I was expecting
instant gratification and that those files would have been moved to the
correct NSD.</font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri"> </font><br><font size=2 face="Calibri"> </font><br><font size=2 color=#002f80 face="Calibri">Mark R.
