I figured out what I screwed up.
Here's the actual cmd in a ksh script:
# get list of stgpools with count of reclaimable volumes
/tsmdata/tsm_scripts/run_cmd_allservers.ksh " \
select stgpool_name, \
count(*) \
from volumes \
where pct_reclaim \> 64 \
and stgpool_name like '%TAPE%' \
group by stgpool_name " \
| sort -k2,2rn \
> $tmpfile1
Note the ' \> 64 '. But our reclamation threshold is 65.
Why did I do >64????
Because I couldn't get ' >= 65' through the shell.
I tried \>\= and \>=, but neither worked. So I
punted and used ' \> 64'. BUT THE CONSEQUENCE of this was
that it picked up fractions like 64.3 which
the "reclaim stgpool . . . threshold=65" would not see,
and there were a lot of those.
I finally got the ksh to work.
This works - you don't need to escape at all: ' >= 65'!!!
Yup, if the equal sign is right after the gt sign then you
don't need to escape the gt sign.
Thanks!

Subject: reclaimable tapes in a stgpool
Is there a way to determine the number of tapes in a stgpool that
are eligible for reclamation?
I tried the following sql on all our TSM instances:
select stgpool_name, \
count(*) \
from volumes \
where pct_reclaim \> 64 \
and devclass_name like '%TAPE%' \
group by stgpool_name "
It returned a list, but when I went and ran "reclaim stgpool <name>
threshold=65"
many of the pools returned that there were no volumes to be reclaimed. I think
I need more qualifiers on the select.
We currently have reclamation running automatically with a
reclaim pct of 65% on the stgpool. I'm trying to move to
manually running reclamation during a window. I don't
want to just issue reclaim stgpool cmds all at once for all
instances to prevent a tape drive storm. I want to start
them gradually, with the stgpools with the most tapes to be
reclaimed starting first.
Thanks
Rick
