Hi All

I have a bit of a conundrum.

I have an Oracle SL8500 library with 6x IBM LTO-6 drives installed.  The drives 
are dual connected. These are being used by multiple AIX 7.1 TSM 7.1 servers in 
a library sharing arrangement.

AIX shows these drives as using the generic LTO driver, rather than the IBM 
Atape driver.

For example

rmt55rh Available 24-T1-01     LTO Ultrium Tape Drive (FCP)

Rather than the expected

vtl00rg Available 24-T1-01     IBM 3580 Ultrium Tape Drive (FCP)  (this is an 
LTO-3 emulated drive on our protectier VTL)

LTO 6 Performance is atrocious.

Running instAtape gives one of the following for each drive

Method error (/etc/methods/cfgAtape -l rmt55rh ):
        0514-045 Error building a DDS structure.

We have no licence keys applied for Data Path Failover.... They come free with 
an IBM library but cost for a non-IBM one ... I'm trying to track down whether 
the licences were purchased back when this equipment was new.

So, does anyone know to  apply the Atape driver to these drives?  I can live 
without DPF for now.

Cheers

Steve
