SYSID(5)		      AFS File Reference		      SYSID(5)

       sysid - Lists file server machine interface addresses registered	in

       The sysid file records the network interface addresses that the File
       Server (fileserver process) registers in	the Volume Location Database
       (VLDB) for the local file server	machine.

       Each time the File Server restarts, it builds a list of interfaces on
       the local machine by reading the	/var/openafs/NetInfo 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
       /var/openafs/NetRestrict	file, if it exists. The	File Server records
       the resulting list in the binary-format sysid file and registers	the
       interfaces in the VLDB.

       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.

       The sysid 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	/var/openafs directory from an
       existing	file server machine to a newly installed one, be sure to
       remove the sysid	file from the new machine before starting the "fs"
       trio of processes, which	includes the fileserver	process.

       A maximum of 15 file server interface addresses can be registered in
       the VLDB.
