Hi,

I think that the IBM Atape driver is not supported on non-IBM libraries,
even if the drives are IBM LTO drives.
You need to use the Spectrum Protect driver.
The IBM Atape driver is only supported on IBM Libraries and stand-alone IBM
LTO drives.

Subject: [ADSM-L] AIX Atape driver on IBM drives in Oracle Library

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
