The problems: I have a similar problem, except this is a DEC TLZ6L-DA jukebox. When hooked up, it also punts to the Exabyte 8200, which is not correct, of course. Worse, it presents TWO devices on a probe-scsi: Target 4 LUN0 and target 4 LUN1 (apparantly the jukebox ctg switching stuff). I can live with switching the cartridges manually for the time being, but it would be nice to know what commands LUN1 supports as well, perhaps a util could be written to cause it to change programmatically when one tape fills. At any rate, I guess I need to know if all these 4mm DATs are basically the same, and one description can be altered to match the vendor's signature and it will be OK? Oh, BTW, the OS is 4.1.4 (apparantly same as 4.1.3 as far as this st_conf.c file goes). Please e-mail as well as post any responses, news is kinda flakey right now. Mail to reply-to address and/or pat@happy-man.com, to make sure I see the response. This is kinda urgent, thanks. >(1) "mt" still says that I have an Exabyte 8mm (although the system > logs messages saying it's an HP 4mm DAT). > >(2) A back up program (Legato's NetWorker) thought that the tape 1/2 > as long as it really was.
