PROG/BACKUP on Alpha OpenVMS fails with Progres Error (43)

DRAFT COPY - Currently under review and edit.

INTRODUCTION:
=============

On OpenVMS when writing blocks to a tape media, you must first
initialze the tape with a label and mount it for access. As the
Progress backup utility tries to accomplish this automatically,
there have been occasions where this must be done manually. Below
shows some of the errors you are likely to encounter if Progress
is unable to write to the tape.

PROGRESS ERROR NUMBER: ERROR TEXT:
====================== ===========================================

(43) Cannot find or open file <device> errno = #


POSSIBLE CAUSE OF ERROR:
========================

The tape device may not be initialized properly. Possible error
numbers you will see are:

errno = 9 %SYSTEM-S-ACCVIO, access violation, reason mask=!XB,
virtual address=!XL, PC=!XL
errno = 16 %SYSTEM-W-BADPARAM, bad parameter value

To find out the errno value on OpenVMS, use the following command
substituting the ERRNO number you received.

$ write sys$output f$message(ERRNO)

DOES THE ERROR INDICATE CORRUPTION: IF SO, WHAT TYPE
======================================== =========================

NO.

CORRECTIVE MEASURES:
====================

Initialize and mount the 4mm or 8mm DAT tape before using the
Progress backup command.

For example:

$ init <devicename> <labelname>
$ mount <devicename> <labelname>
$ prog/backup demo <devicename>

REFERENCES TO WRITTEN DOCUMENTATION:
