CPIO Backup End of Media
I'm having problems getting backups working on SCO OpenServer 5.7.
using the following command:
find / -depth -print | cpio -ocvB -O /dev/rct0
some files are backed up then the following error is reported:
Reached end of medium on output.
Device /dev/rct0: Change to part 2 and press RETURN key. [q] q
The tape device is DDS4 (20Gb) and there is only 3Gb of data on the machine so there should be plenty of room on a single tape.
I've tried a different tape drive with the same issue so I don't think it's a hardware problem.
Any help would be appreciated.

AMMT(8) System Manager's Manual AMMT(8)
NAME
ammt - Amanda version of mt
SYNOPSIS
ammt [ -d ] [ -f|-t device ] command [ count ]
DESCRIPTION
Ammt provides just enough of the standard mt command for the needs of Amanda. This is handy when doing a full restore and the standard mt
program has not yet been found.
Ammt also provides access to the Amanda output drivers that support various tape simulations.
See the amanda(8) man page for more details about Amanda. See the OUTPUT DRIVERS section of amanda(8) for more information on the Amanda
output drivers.
OPTIONS
-d Turn on debugging output.
-f device
Access tape device device. If not specified, the TAPE environment variable is used.
-t device
Same as -f.
command count
Which command to issue, and an optional count of operations.
COMMANDS
Each command may be abbreviated to whatever length makes it unique.
eof|weof count
Write count (default: 1) end of file marks (tapemarks).
fsf count
Skip forward count (default: 1) files.
bsf count
Skip backward count (default: 1) files.
asf count
Position to file number count (default: 0) where zero is beginning of tape. This is the same as a rewind followed by a fsf count.
rewind Rewind to beginning of tape.
offline|rewoffl
Rewind to beginning of tape and unload the tape from the drive.
status Report status information about the drive. Which data reported, and what it means, depends on the underlying operating system, and

EOT Indicates the drive is at end of tape.
