OS: Tru64 Unix - Ver 4.0f - DEC 3000(M800).
When I tried to erase some tapes (std DDS(1) 125) on a newly reinstalled OS with the following command ...
# mt -f /dev/nrmt0h erase
And returned the following error ...
Dev erase 1 failed - no such device or address
Little confused as we (myself and a college) were able to vdump the contents of the /var directory to tape with success.
Any suggestions ??? Will try the dd if=/dev/random of=/dev/tape obs=x in the meantime.

I'm using tar and so far so good, but how can I view ALL files without having to fast forward and rewind the tape? Let's say I append 100 files onto the tape. Having to fast forward 100 times until I find the file I want is kinda tedious. (3 Replies)

MT(1) GNU CPIO MT(1)
NAME
mt - control magnetic tape drive operation
SYNOPSIS
mt [-V] [-f device] [--file=device] [--rsh-command=command] [--version] operation [count]
DESCRIPTION
This manual page documents the GNU version of mt. mt performs the given operation, which must be one of the tape operations listed below,
on a tape drive.
The default tape device to operate on is taken from the file /usr/include/sys/mtio.h when mt is compiled. It can be overridden by giving a
device file name in the environment variable TAPE or by a command line option (see below), which also overrides the environment variable.
The device must be either a character special file or a remote tape drive. To use a tape drive on another machine as the archive, use a
filename that starts with `HOSTNAME:'. The hostname can be preceded by a username and an `@' to access the remote tape drive as that user,
if you have permission to do so (typically an entry in that user's `~/.rhosts' file).
The available operations are listed below. Unique abbreviations are accepted. Not all operations are available on all systems, or work on
all types of tape drives. Some operations optionally take a repeat count, which can be given after the operation name and defaults to 1.
eof, weof
Write count EOF marks at current position.
fsf Forward space count files. The tape is positioned on the first block of the next file.
bsf Backward space count files. The tape is positioned on the first block of the next file.
fsr Forward space count records.
bsr Backward space count records.
bsfm Backward space count file marks. The tape is positioned on the beginning-of-the-tape side of the file mark.
fsfm Forward space count file marks. The tape is positioned on the beginning-of-the-tape side of the file mark.
asf Absolute space to file number count. Equivalent to rewind followed by fsf count.
seek Seek to block number count.
eom Space to the end of the recorded media on the tape (for appending files onto tapes).
rewind Rewind the tape.
offline, rewoffl
Rewind the tape and, if applicable, unload the tape.
status Print status information about the tape unit.
retension
Rewind the tape, then wind it to the end of the reel, then rewind it again.
erase Perform long erase of tape. If count is 0, perform short erase of tape (some devices do not support this).
mt exits with a status of 0 if the operation succeeded, 1 if the operation or device name given was invalid, or 2 if the operation failed.
OPTIONS
-f, --file=device
Use device as the file name of the tape drive to operate on. To use a tape drive on another machine, use a filename that starts
with `HOSTNAME:'. The hostname can be preceded by a username and an `@' to access the remote tape drive as that user, if you have
permission to do so (typically an entry in that user's `~/.rhosts' file).
--rsh-command=command
Notifies mt that it should use command to communicate with remote devices instead of /usr/bin/ssh or /usr/bin/rsh.
-V, --version
Print the version number of mt.
