Purpose of three extra bytes (00 xx 00) is unknown for me but 00 xx 01 it loads tape number x. 00 00 00 load next tape.

A "mt rewoffl" should do the same thing as your camcontrol mt rewoffl cause changer to rewind current tape, then unload it. It doesn't load next tape. -- Dmitry Samersoff, [EMAIL PROTECTED], ICQ:3161705 http://devnull.wplus.net * There will come soft rains ...

Re: HP Type C1559 problems
I'm using a HP SureStore 24x6 too, and have no problems talking to it with chio. I suspect there's some screwy optioning nonsense for the tape motion stuff that's wrong. louie To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
Re: HP Type C1559 problems
It sounds to me that you have this device strapped to be in 'stacker' mode- the command you're sending is the same as an 'mt offline' command- so it's loading the next tape in the changer. that means it won't show up as a changer on lun 1. I haven't seen one these beasts for 5-6 years- I don't recall what the switch settings are, but IIRC HP switch settings made no sense.

I'm not so lazy as you belive ;-)) I tried all above before going to camcontrol. mt can rewind, erase end so on current tape, but can't change current slot number. chio report error for every comand except "chio status" . I find now (after lots of experiments) that sending raw SCSI command helps me. Right command causing changer to load next tape looks like: camcontrol stop -n sa -t 100 -v camcontrol cmd -n sa -t 100 -v -c "1B 00 00 00 00 00" To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

HP Type C1559 problems
I have problem with HP SureStore 24x6 I can read(write) only from one tape from catridge Could anybody send me ether shell or C (preferable) sequence need to read tapes one by one? i.e something like: cat /dev/rsa0 camcontrol cmd -n rsa0.ctl -c "1B 00 00" cat /dev/rsa0 Thank you! -- Dmitry Samersoff, [EMAIL PROTECTED], ICQ:3161705 http://devnull.wplus.net * There will come soft rains ...
