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 \&\fI/var/lib/openafs/local/NetRestrict\fR file, if it exists. The File Server records the resulting list in the binary-format \fIsysid\fR file and registers the interfaces in the \s-1VLDB.\s0 .PP When the Cache Manager requests volume location information, the Volume Location (\s-1VL\s0) 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 \s-1AFS\s0 data stored on a multihomed file server machine. .SH "CAUTIONS" .IX Header "CAUTIONS" The \fIsysid\fR 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 \fI/var/lib/openafs/local\fR directory from an existing file server machine to a newly installed one, be sure to remove the \&\fIsysid\fR file from the new machine before starting the \f(CW\*(C`fs\*(C'\fR trio of processes, which includes the \fBfileserver\fR process. .PP A maximum of 15 file server interface addresses can be registered in the \&\s-1VLDB.\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBNetInfo\fR\|(5), \&\fBNetRestrict\fR\|(5), \&\fBvldb.DB0\fR\|(5), \&\fBfileserver\fR\|(8) .SH "COPYRIGHT" .IX Header "COPYRIGHT" \&\s-1IBM\s0 Corporation 2000.
