<P>Lists file server machine interface addresses registered in VLDB
|
||
|
<P><STRONG>Description</STRONG>
|
||
|
<P>The <B>sysid</B> file records the network interface addresses that the
|
||
|
File Server (<B>fileserver</B> process) registers in the Volume Location
|
||
|
Database (VLDB) for the local file server machine.
|
||
|
<P>Each time the File Server restarts, it builds a list of interfaces on the
|
||
|
local machine by reading the <B>/usr/afs/local/NetInfo</B> file, if it
|
||
|
exists. If the file does not exist, the File Server uses the list of
|
||
|
network interfaces configured with the operating system. It then
|
||
|
removes from the list any addresses that appear in the
|
||
|
<B>/usr/afs/local/NetRestrict</B> file, if it exists. The File
|
||
|
Server records the resulting list in the binary-format <B>sysid</B> file
|
||
|
and registers the interfaces in the VLDB.
|
||
|
<P>When the Cache Manager requests volume location information, the Volume
|
||
|
Location (VL) Server provides all of the interfaces registered for each server
|
||
|
machine that houses the volume. This enables the Cache Manager to make
|
||
|
use of multiple addresses when accessing AFS data stored on a multihomed file
|
||
|
server machine.
|
||
|
<P><STRONG>Cautions</STRONG>
|
||
|
<P>The <B>sysid</B> file is unique to each file server machine, and must
|
||
|
not be copied from one machine to another. If it is a common practice
|
||
|
in the cell to copy the contents of the <B>/usr/afs/local</B> directory
|
||
|
from an existing file server machine to a newly installed one, be sure to
|
||
|
remove the <B>sysid</B> file from the new machine before starting the
|
||
|
<B>fs</B> trio of processes, which includes the <B>fileserver</B>
|
||
|
process.
|
||
|
<P>Some versions of AFS limit how many of a file server machine's
|
||
|
interface addresses that can be registered. Consult the <I>IBM AFS
|
||
|
Release Notes</I>.
