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