My thought process was this: there was one volume (the un deletable volume) a=
ssociated with the oldaddr and no volumes with the newaddr. There were also n=
o protection groups containing either machine address. The oldaddr is on a s=
ubnet that I can't get access to so by changing oldaddr to newaddr which us o=
n a reachable subnet I was hoping to do a syncserv to clear out the phantom e=
ntry.

This wasn't one of the caveats mentioned in the man page. Had I known that I=

vos delentry doesn't work-- I tried that a bunch of times before I posted to=
 the list. Heres the error I get:

Could not delete entry for volume 536988828
You must specify a RW volume name or ID (the entire VLDB entry will be delet=
ed)
VLDB: no such entry
Deleted 0 VLDB entries

Thanks!
