Ladies, gentlemen,
a new, replaced LTO drive gives me headaches - in the following situation:
OS: MS Win2k Advanced Server, 5.00.2195, SP2
TSM: Storage Management Server for Windows - Version 5, Release 1, Level 0.0
After having worked with no probs afaik, last week one of my two HP
ultrium LTO drives died and was replaced by dell (guarantee/bronce
contract). Following this, i wittnessed for two days the cumbersome
process of firmware-updating the library (PV136T, equals a ADIC Scalar
100, or so I am told), after which the system seemed ok. I deleted drive
and path definitions and hoped for the best. This is what I have seen
two days later:

...
This is taking up my already few scratch tapes too fast...
(By the way: What is the correct way to turn these tapes into scratch
tapes again? move data into the storagepool, and then manually turn them
to scratch-status again? or do i miss something there?)
Tests done with the Dell-provided software tools have not given any hint
on problems occuring in the library. I have now been advised to swap the
two drives (one becomes two and vice versa) and see if the problem
persists - but my problem now is that I would not know how to do
reasonable testing.
I don,t know how to trigger migration process manually (searched the
admin ref pdf to no avail),
but even if I did, there is only so many migrations I can do, and then I
am stumped.
I don,t know how to advise TSM to move data using a defined drive - say,
from 1 to 2, and not from 2 to one - how can this be done?
I am quite limited in space and don,t have copy pools, so I am a bit
hesitant to move data with a possibly faulty drive and breaking
something - is there a clever approach doing a copy onto a single tape
volume? Again, I checked the guide but did not see anything wrt this...
Any input would be very much appreciated,
greets, tobi
