SMS managed tape can tell the difference, and is the best way to manage multiple device types. If you do not have an ATL you can define a manual tape library for some or all of your drives to manage allocations.
>>> Dennis McCarthy <[email protected]> 8/3/2009 9:03 AM >>> Hi Everyone, It appears we will be getting 3592 tape drives to eventually replace the 3590 MagStar units. I'm told the media for the two devices is not compatible. However, I'm also told that the 3592's are defined as 3590's in the IODF. If this is true, I'm assuming the hex value of the 3592 will be the same as the 3590 (X'78048083'). If this is true, when a job requests a file for input, and that file is on a tape created on a 3590 MagStar, what is to prevent a D/T 3592 from being allocated as the input device? I've experimented with coding a "UNIT=" parm, but the catalog knows the device type (X'78048083') and simply allocated the correct device. I understand I can use esoterics to control the allocation of the output device -- but I'm concerned with how the system handles allocation of the INPUT device.
