What we found was that, after having run a COPY STGPOOL and then shipping
the new tapes offsite, if we started reclamation it tended to recopy the
very volumes that we had just created and vaulted.  Our vault had grown to
some 700-800 volumes.  With weekend-only reclamation the pool grows to
around 400 volumes by Friday but then drops back down to around 100.  This
is with some 60 clients, all collocated.  Take a hard look at your
reclamation cycles and what volumes are being used for input.

Re: tape use question






We run daily reclamation to avoid long reclamation sessions that can go
on for some time.  We also only send out full tapes to avoid sending out
tapes to often.

How often are you doing reclamation on your vault pool?  We used to do
reclamation daily and found ourselves in a similar situation.  We
changed to only reclaiming once a week and like that much better.

tape use question






Just a quick question to the experienced TSmers out there

Does anybody have any idea or suggestions on how we can slow down our
tape usage.
We are up to 70 tapes going out the door each day and its growing more
by the month.
We have 6 ,,3594 tape libraries , about 60 win NT servers 12 AIX boxes
not including a SP maxed out.
We find our self constantly running vault retrieve since the tape
shortage is getting worse by the day.
Any suggestions would help .

TSM version 5.1

Thanks
