I am looking into using collocation for my ADSM setup but I only have 1
3490E unit with 10 slots but only one drive.  How can I force adsm to write
multiple nodes to 1 tape if neccessary ?

Thanks,

Joel McCarty

     Peter,
     I'm sure that is not a problem.  We use collocation and force adsm to
     put multiple nodes on a tape by limiting the number of scratch tapes
     in the storage pool and have never had problems with i/o errors.

The problem is that i am running Collocation=yes, but there is still data
from different
notes on the same tape. And that causes the I/O error.

ADSM can not handle data from different serveres on the same tape, when the
tapepool
is defined with Collocation=yes.

I agree that if the problem is an I/O error, i should handle that problem
first.

Peter,

if you have I/O errors, you should investigate in order to solve them
first of all. I don't think they are in any way related to a "should I
collocate or not collocate" Hamlet dilemma.

Thank you
