Last week, I added a fourth frame onto our 3584, along with 4 new LTO2 tape drives. I have not defined the new drives in TSM yet, because I'm still trying to find out the best way to run in a mixed LTO1-LTO2 environment.
I've read that in version 5.2.X you do not have to logically partition your library to use both drives, but I'm still confused about whether I will need to set up separate device classes and storage pools. All of my media is LTO1. Can I simply set my existing device class format from "DRIVE" to "ultriumc", define the new drives, and just let things rip? All I really want to do is let the LTO2's perform like LTO1's since I'm not using any LTO2 media. Is anyone running a mixed LTO1-LTO2 environment? If so, how are you doing it? Any help or advice is much appreciated!
