There are backing tapes in the library that I believe are not addressable from the system while the ones facing the channel are all emulated. Thanks for what should have been an obvious answer, especially since I have very recently used the Q DASD DETAILS command. I must be getting too old.

I'm not sure if it can tell the difference between a virtual and physical drive. We don't have any physical drives in IBM libraries on VM. Here are the responses from a physical drive in an STK silo followed by an IBM VTS drive: q ta details 340 TAPE 0340 SEQUENCE NUMBER ----- LIBPORT - Ready; q ta details d800 TAPE D800 SEQUENCE NUMBER 31000 LIBPORT 1 Ready; Dennis O'Brien "The art of taxation consists in so plucking the goose as to obtain the largest amount of feathers with the smallest possible amount of hissing." -- Jean-Baptiste Colbert, 17th-century French minister of finance From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Schuh, Richard Sent: Thursday, April 22, 2010 17:10 To: [email protected] Subject: [IBMVM] VTS Devices Is there any way to tell if a tape drive on the system is a VTS virtual drive? Visual inspection is not an option as the system and peripherals are over 1000 miles from here. Regards, Richard Schuh
