Greetings TSMers, I am remotely helping a coworker with an AIX system running TSM 5.2.2, and AIX 5.2 (not sure which maintenance level, but I think it is ML2). He is trying to install a ADIC iScalar 2000 library with LTO2 drives in it. We have the TSM device drivers fileset installed, and the library and drives zoned into one of the FC adapters. When we ran config manager and used the TSM Devices smit dialogue to scan the FC adapter to configure the device, it discovered the LTO tape drives, and assigned /dev/mt0, /dev/mt1 addresses to them just fine. But it didn't configure the autochanger, and we can't figure out why. The adapter we are using already has STK tape drives already on it, and they are working fine. My coworker checked and there is no conflict with the LUNs we are using. One thing that I checked was the FC adapter setting. All the adapters on this system are set to FC-AL. I have noticed that the FC adapters under AIX seem to come set to FC-AL by default, and you need to change them to FC Point-to-Point if you want them that way. I have also saw on another system once that we could not see the autochanger for a IBM3584 when the FC adapter was set to FC-AL. But we could see the drives. When we changed it to FC Point-to-Point then we had no problem configuring the autchanger and drives and everything worked. Has anybody seen this before? I would like to just try it and see, but since there are already STK drives on the FC adapter, changing the adapter to Point-to-Point would affect those, and I don't want to guess and be wrong and whack those drives.
Best Regards, John D. Schneider
