I wondered about messages like that when I turned SANDISCOVERY on.  I found 
that TSM must run as root (in AIX) to access the devices at the OS level.

Hi,

I went ot turn on SANDiscovery on a new server and I get the message :

ANR1789W Get HBA target mapping failed.

How can I know which device is involved ?

I run TSM 5.3.4.2 (old I know) on AIX 5.3
