mkdev tape problem

SCO 5.0.5

Our system hiccuped last week during mkdev tape command.
Actually was at the point where it generated a kernel to reflect the new scsi tape I was trying to add and the system appeared to hang and we aborted the process.

starting fresh no tape devices defined.
run mkdev tape define 1 scsi tape device
regen the kernel and reboot
and 3 tape devices appear (0,1,2).
Can not delete device 1 or 2 but deleting device 0 deletes all 3.

Must be value stuck somewhere in the system anyone know where to look or how to fix this ? THANK YOU

tapeinfo - report SCSI tape device info SYNOPSIS
tapeinfo -f <scsi-generic-device> DESCRIPTION
The tapeinfo command reads various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It issues raw commands directly to the tape drive, using either the operating system's SCSI generic device ( e.g. /dev/sg0 on Linux, /dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems. One good time to use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API, 'tapeinfo' will report a more exact description of what went wrong. Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information. OPTIONS
The first argument, given following -f , is the SCSI generic device corresponding to your tape drive. Consult your operating system's doc- umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0). Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls them. Under Linux, "cat /proc/scsi/scsi" will tell you what SCSI devices you have. BUGS AND LIMITATIONS
This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT). AVAILABILITY
tapeinfo is currently being maintained by Eric Lee Green <> formerly of Enhanced Software Technologies Inc. The 'mtx' home page is and the actual code is currently available there and via CVS from . SEE ALSO
