Not especially. Apparently afs 3.3 added supprt in the vlserver for
allowing clients to change their addresses. AFS 3.4 made this automatic.
The AFS 3.4a release notes say:
// AFS 3.4a makes the vos changeaddr command obsolete. File server
// machine addresses are registered automatically with the VL Server each
// time the File Server restarts.
It was suggested by jweiss that it was necessary to rm a file
prior to starting the fileservers to make this function. While this
sounded vaguely familiar at the time, I can't find any documentation
of it now, and a cursory glance at source didn't yield anything.
Here's the section on 'vos changeaddr' from the 3.4a relnotes,
which are left in there from the 3.3 relnotes.
// The vos Commands 12.8. The vos changeaddr Command
//
// AFS 3.3 Changes The vos changeaddr command changes a file server's IP
// address. Changing the IP address of a file server was a difficult task
// in earlier versions of AFS. After changing the IP address, you had to
// run the vos syncserv and vos syncvldb commands. Then you had to issue
// the vos remsite command to remove site information associated with the
// ReadOnly volumes under the old IP address. A new vos command, vos
// changeaddr, allows you to change a simple file server's IP address
// easily.
//
// Note: If you are using AFS 3.4a VL servers, the vos changeaddr command
// has no
//
// effect on file server addresses. AFS 3.4a VL servers automatically
// register the IP addresses of file server machines upon restarting the
// fileserver process.
//
// The syntax of the new command follows:
//
// vos changeaddr -oldaddr <original IP address> -newaddr <new IP
// address> [-cell <cell name>] [-noauth] [-localauth] [-verbose] [-help]
//
// Arguments:
//
// -oldaddr Specifies the old IP address of the file server whose IP
// address you are changing. -newaddr Specifies the new IP address of the
// file server. -cell Specifies the cell in which to run the command; the
// default is the local cell. Do
//
// not use this flag with the -localauth flag; the -cell argument and the
// -localauth flag are mutually exclusive.
//
// -noauth Tells the Volume Location (VL) servers to assign the identity
// system:anyuser
//
// to the issuer.
//
// -localauth Constructs a server ticket using a key from the
// /usr/afs/etc/KeyFile file. Do
//
// not use this flag with the -cell argument; the -cell argument and the
// -localauth flag are mutually exclusive.
//
// -verbose Tells the Volume and VL servers to report on what they are
// doing as they
//
// execute the command.
//
// The vos Commands -help Prints the online help for this command. All
// other valid options specified with
//
// this option are ignored.
//
// Note: This command does not change IP addresses contained in any
// protection groups
//
// that you have defined with the pts creategroup command. Use the pts
// rename command to change IP addresses in existing groups.
//
// Changing the IP address of a Ubik database server involves additional
// changes. Refer to the AFS System Administrator's Guide for more
// information.
//
// Examples: The following command changes the IP address of a simple
// file server from 128.21.16.214 to 128.21.16.221:
//
// % vos changeaddr -oldaddr 128.21.16.214 -newaddr 128.21.16.221
// -localauth
