Thanks to all who have replied. All, do linux users use a mouse. I would think that mouse tracking would be a nightmare in the VM environment. I remember way back when we used to ask users monitoring jobs in OS/VS1 to not hit the enter key constantly. It's ok for a few, but when you have 5,000

LTO4 tapes attached via FCP

2009-05-14 Thread Craig Dudley
Hi, I wonder if anyone is attaching a LTO4 (Linear Tape Open, Generation 4), via FCP, to a z9 or z10 running zVM 5.4? And if yes, are there any zVM utilities (DDR, SPXTAPE, etc) that support LTO4s? Or is LTO4 support while attached to a FCP limited to zLinux? Or does zLINUX even support LTO4s?
