Zlatko,

Here's the output you requested.  As you can see, same model and
microcode levels (it's the same across all five drives.

I've done the same Show Libr on our other two servers, one with
3590B1A's, one with 3590E1A's.
The B1A's:
       RMT0 (/dev/rmt0):
               type=8, mod=17, busy=0 online=1,

The E1A's: (Sun server, others are AIX)
       RMT0 (/dev/rmt/3st):
               type=8, mod=48, busy=0, online=1,


The problem we are having with the one drive is that some tapes that are
written on it are not mounted on any other drives.  When a session needs
that tape and RMT2 is busy, the session immediately fails, the tape is
not mounted.

We have not removed the device and readded it through AIX, as we feel we
may risk losing the ability to mount these tapes.  But comparing the
output from the Show Libr commands, is it possible that RMT2 is correct
(it is the same as the 3590E1A's on the other server) and the other four
drives are not (they are the same as the 3590B1A's on the other server)?

Thanks,
Mike
