Re: Autochanger with C1537A and Omniback : cannot open exchanger control device
Is it correct you are using OmniBack 3.0 . It has been out of support for some time now. I can't find information but it is perhaps not supported on HP-UX 11.11. You can test with the "uma" command (/opt/lbin/uma). It is similar to "mc" but a OmniBack utility. If you get problem with this too I think you need to upgrade OmniBack. As the "mc" command works your drivers seems OK. Have a look at man pages for uma.

Re: Autochanger with C1537A and Omniback : cannot open exchanger control device
you have created you exchanger control devicefile with the wrong minor number (i think this is the minornumber of your tape).
You should do this:
- delete your created specialfile /dev/rmt/1m
- "ioscan -fnkC autoch" which will give you path to your exchanger control device
- "ll" the devicefile of your exchanger control devicefile /dev/rac/... to get the right minor number
- "lsdev -d sctl" to get the major number of the sctl driver
- mknod /dev/rmt/robot c
- check the devicefile by using the "uma" of Omniback "/opt/omni/lbin/uma -ioctl /dev/rmt/robot"; then you will get a prompt where you can do a e.g. "stat S" to get the status of your slots
- now modify your Omniback Library config accordingly
regards
Gerrit

203 is the correct minor number if HP-UX 11.11, perhaps it is different in previous versions. I use this driver for our library and it works without problem.

Re: Autochanger with C1537A and Omniback : cannot open exchanger control device
And ( for Ashwani) why I have to try 231 for Major Number? From where do you get this number?
Also , If I try uma utility I get the same error:
Cannot open exchanger control device ( not a scsi II Exchanger)

Re: Autochanger with C1537A and Omniback : cannot open exchanger control device
I have remade the special file with
mknod /dev/rmt/0pick 203 0x013100
and now it seems to be working.
Thanks to all you for the answers, Mauro
