| 3 | sysid - Lists file server machine interface addresses registered in VLDB | |
| 4 | ||
| 5 | =head1 DESCRIPTION | |
| 6 | ||
| 7 | The F<sysid> file records the network interface addresses that the File | |
| 8 | Server (B<fileserver> process) registers in the Volume Location Database | |
| 9 | (VLDB) for the local file server machine. | |
| 10 | ||
| 11 | Each time the File Server restarts, it builds a list of interfaces on the | |
| 12 | local machine by reading the F</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 removes | |
| 15 | from the list any addresses that appear in the | |
| 16 | F</usr/afs/local/NetRestrict> file, if it exists. The File Server records | |
| 17 | the resulting list in the binary-format F<sysid> file and registers the | |
| 18 | interfaces in the VLDB. | |
| 19 | ||
| 20 | When the Cache Manager requests volume location information, the Volume | |
| 21 | Location (VL) Server provides all of the interfaces registered for each | |
| 22 | server machine that houses the volume. This enables the Cache Manager to | |
| 23 | make use of multiple addresses when accessing AFS data stored on a | |
| 24 | multihomed file server machine. | |
| 25 | ||
| 26 | =head1 CAUTIONS | |
| 27 | ||
| 28 | The F<sysid> file is unique to each file server machine, and must not be | |
| 29 | copied from one machine to another. If it is a common practice in the cell | |
| 30 | to copy the contents of the F</usr/afs/local> directory from an existing | |
| 31 | file server machine to a newly installed one, be sure to remove the | |
| 32 | F<sysid> file from the new machine before starting the C<fs> trio of | |
| 33 | processes, which includes the B<fileserver> process. | |
| 34 | ||
| 35 | A maximum of 15 file server interface addresses can be registered in the | |
| 36 | VLDB. | |
