That's taught me something, I didn't realise that the storage node affinity
list was used, let alone taking priority over "read hostname".

I see now that the problem has been solved, so that's good, however my
first answer was based on the situation of two separate storage nodes with
their own devices. There was no mention of shared libraries in the original
question. Thus, NetWorker would take account of the location of the volume
and attempt to load it in the relevant location. The only way to change the
location would have been to move the tape and then load or inventory it.
With shared libraries it's a slightly different thermos of seafood.
