Too many DRM tapes leaving 3949 library daily.
2003-10-13 14:19:30
Hello Group,
I am fairly new to using an automated library. We've just
moved to one from a manual library. I am having a problem with too many
tapes from my offsite pool leaving the library every day when MOVE DRM is
run. Our core group of critical servers are going to a collocated pool. The
number of nodes using this pool is approximately 45. My problem is that
between 150 and 160 tapes are ejected from the library on a daily basis! An
equal number of tapes are returning from offsite. I expected that the number
of tapes going offsite each day would be approximately equal to the number
of nodes using the collocated pool (Plus a few more tapes for the
non-collocated copypool and the DBB). Any advice on what I'm doing wrong?
I am running TSM 5.2.0.0 on an AIX-RS/6000. I have a 3494 library
which is shared with an OS/390 mainframe with 6 3590 drives dedicated to
TSM. Below are my maintenance scripts:
