So it was writing direct to tape.  And after the initial failure
did not retry.  Sounds like the same situation Jeff Allison
describes in the thread "spanning tapes".

I wonder what is the best approach to a "failed" dump.  Note, it is
not a failed taping such as would occur if the taping were coming
from the holding disk.  The reason for the dump failure was tape
related, but the dump did fail.

Is it reasonable to restart the entire dump of the DLE?
Are there any other "dump" failures that are retried?

GH pointed out that Jeff's total dump time was over 15 hours.
As the failed DLE was the only large (and I think only remote)
DLE, most of those 15 hours were spent on the one dump.  Should
another 15 hours be expended on the retry of a failed dump?

Just soliciting opinions.
