inquiry /dev/iXOS_SCSI0/4,0
0000002 /dev/iXOS_SCSI0/4,0 is TOSHIBA's CD-drive "CD-ROM XM-
3501TA"
0000003 ProRevL 1875, Firmware 07/06/95
If you encounter a “Bad file number” error, you should check for known
devices by
inquiry /dev/iXOS_SCSI?/*
Alternatively you may try to attach a drive in a jukebox as a single device
to check if this drive is alright.
The same procedure as for drives applies to SCSI changers/robots as
well, except that you can't use them as single drives of course.
If your jukebox has a changer which is adressed by a serial line, you
should check for logfile errors of type either
tty_open(xxx) - No such file or directory
or in case of NSM jukeboxes
nsm_recv(): got 0 bytes garbage:
which are caused by an incorrect robot line in the device file.
Please make as well sure for NSM jukeboxes that the robid is correct -
check their manual for the details.
You should check the manual of your jukebox as well to ensure that the
order of drives in the device file corresponds exactly to the ordering which
the changer has in mind. This is a common cause of problem, and some-
times the manual are not very valuable in this respect.
If you changed CDs in the jukebox manually or nothing else helps, you
should stop the server, delete the save file of the corresponding jukebox
and start the server again. This will cause the jukebox to rescan all slots.
9.3 Problems with CDs
A CD is labelled as bad CD, although it can be read perfectly well on
other CD drives
In most cases this is due to the fact that you exceeded the number of CDs
given in your licence file. All excess CDs simply can not be addressed by
jukeman.
Moreover any CD not which does not comply to the iso9660 standard or
its extensions Rock Ridge or Joliet is labelled as bad CD as well.
