i tried to remove the old ip address. it displayed the following message.
[root@afs ~]# vos changeaddr 117.108.x.x -remove
Could not remove server 117.103.x.x from the VLDB
VLDB: volume Id exists in the vldb

at this moment, could i use "vos remove 117.108.x.x a  cfliu" to
remove the old ip address entries on by one? i'm not sure will this
affect the new ip address afs server or not? :$

or should i use "vos delentry"? sorry for my dump questions. thank you agai=
n!

best, sam
