Hi Boris, Datapath failover is possible, on condition having bought the feature with your 3584 library.
First of all, check if you got the necessary key to enable the feature (should be written on a sticker on the inside of rear side of your library) Then, to enable datapath failover, in AIX issue : dpf_keys -a key_number To enable datapath failover on a drive : chdev -l rmt1 -a alt_pathing=yes To enable control path failover on a smc device : chdev -l smc1 -a alt_pathing=yes to enable on all drives in one shot : /usr/lpp/Atape/instAtape -a This is described in the IBM Ultrium device drivers Installation and user's guide (GA32-0430-0.3) Hope this helped ...

Our Unix colleagues have installed and configured AIX and Atape. Every Drive was connected with both Ports to two different "Fabrics". So each Drive is seen in AIX two times with different names. For example: Port0 of the Drive => /dev/rmt10 Port1 of the Drive => /dev/rmt50 Today in TSM I've configured all Drives on Port 0 (/dev/rmt10 - /dev/rmt17). Is there a way that TSM or AIX can automatically handle a Path Failover for Ports? My AIX colleagues told me, that under AIX is no way to use the same device (for example /dev/rmt10) in a Path Failover for Ports as /dev/rmt10. I than must use /dev/rmt50). In TSM I don't know any mechanism to automatically handle that problem. I missed something in the TSM PATH definition like "If /dev/rmt10 is not available so use automatically /dev/rmt50). Any ideas. Thanks, Boris
