SCO UNIXWare Backup Tape Stuck

We have a SCO UnixWare system version 7.1.3, running a front end ERP system on a Compaq/HP Proliant ML370 server.

Compaq ProLiant ML370 Server

I change the tape everyday to do a daily back up. When I pressed the eject button last night it failed to spit the tape out.....HELP.

1) Is this now buggered ?
2) Is there a command that can eject the tape ?

What tape drive is it? DLT?, DAT? or what?

Its a DAT Format.

Most DAT drives allow you to press and hold the ject button for several seconds to forceably eject the tape.

The tape may also be "locked" in the drive by a SCSI command (which can be left in place when a job aborts). If you reboot the system, the SCSI adapter will issue a SCSI bus reset before the bus is scanned for devices. At that point it may be possible to eject the tape by pressing the button.

Many SCO O/S's do include the command "tape" for various operations. Try:

Code:
tape unload

and

Code:
tape help

or
Code:
tape -help

If none of that works then it will probably mean taking the covers off the DAT drive and finding the little wheel which you need to turn several thousand times to eject the tape.

I tried those commands but got this msg:

# tape unload
Invalid command: unload

tape usage: tape [-<type>] <command> [device]
type: c (non-SCSI) or s (SCSI)
Cartridge tape commands:
reten - retension the tape
erase - erase and retension tape
reset - reset controller and drive
rewind - rewind tape controller
rfm - skip to next file

So I tried

# tape reset:

UX:tapecntl: ERROR: Device open failure.
UX:tapecntl: ERROR: Please check tape or cables are installed properly.
Operation may not be valid on this controller type.

# tape rfm gives:

UX:sh: ERROR: ^C^Ctape: Not found

Looking at your post how about:

Code:
tape -s reset /dev/rct0

(I assume /dev/rct0 is your tape device?)

I get the same message:

UX:tapecntl: ERROR: Device open failure.
UX:tapecntl: ERROR: Please check tape or cables are installed properly.
Operation may not be valid on this controller type.

How can I identify what my tape device is ? I mean how can I tell if it is indeed /dev/rct0 ?
