to follow up to myself here i have managed to get the single drive working
fine - The issue now seems to be with the changer.

Using mtx i can load and unload tapes but when i run amcheck i get the
following error

amcheck-server: could not get changer info: could not determine current
slot, are you sure your drive slot is 1

I have changed all references to nst0 to point to nst1 in my config for this
setup but still this error - i have searched the archives for this one but
can't seem to find a solution.

Can anyone help out here?

thanks
