I had a similar problem with my library. What I did is "qu path" and see
if they all show online=yes. If not what I did was "update path TSM
RMT0  srct=server destt=drive library=lto3583.0 device=/dev/rmt0
online=yes" and from there on they started working. BTW I am working on
a 3583 L72, just for reference since you did not mentioned the library
type model you have.
