I am trying to use the vmchange command on a Solaris master server to reset
some of the media properties in my media database to their default values
(as reported by vmquery).  This command works:

         vmchange -vltsent "01/09/2003 13:40:25" -m 000001

But this command does not:

         vmchange -vltsent "00/00/0000 00:00:00"

(It just prints out the usage for the vmchange command.)

Also, this command works:

         vmchange -vltname "IronMountain" -m 000001

but this command does not:

         vmchange -vltname "" -m 000001

(I get this message:  Could not change media ID 000227: invalid offsite
location (142).)

It seems like vmchange is doing some sort of parameter validation and is
choking on "00/00/0000 00:00:00" and "" as parameters.  I suppose I could
use vmchange so set these values to a valid, but meaningless, value (e.g.
"01/01/1970 00:00:00", but I really want to set these values back to their
defaults.  Don't ask why, I just do.  :)  I've used the strings command to
look through the vmchange binary to see if there are any undocumented
options that I could use, but came up empty.  

So, can anyone tell me how I can use vmchange (or another command) to set
the vault name, vault sent and vault return values back to their defaults?  

Thanks,
