Does this problem always occur or only when your default directory is set to a
search list (e.g. SYS$SYSROOT:[SYSMGR] on a VAXcluster). In the latter case the
problem does not only occur for tapes, but also for disk directories. I do not
completely understand the problem. But try the following commands when you have
a cluster:

$       SET DEFAULT SYS$SYSROOT:[000000]
$       DIRECTORY SYS$SYSDEVICE

You will also see each file listed twice.
