Setting up a new service machine

The service machine should have the name FMthrong, e.g throng FMALEPH, FMDELPHI, etc. The FATMEN servers may have any names, provided that suitable NAMES file entries are established. The account created requires a 191 disk of sufficient size to maintain the expected file catalogue information. Some 800 bytes are required per file catalogue entry, thus for a catalogue containing 15000 files, about 20 cylinders are required. A 193 disk is required for maintaining journal information. This disk should be at least 5 cylinders.

Table:  Mini-disks required for FATMEN service machines

 +-191--+-Disk-for-FATMEN-RZ-file,-log-file-and-------------------------+
 |      | PROFILE EXEC. The profile exec contains only one     |
 |      | line - 'EXEC FATPROF' 20 cylinders is normally       |
 |      | sufficient for an initial allocation for this disk.           |
 |      |                                                               |
 | 192  | Link to the disk containing the server code and EXECs. At     |
 |      | CERN, these are kept on the 191 disk of userid FATMEN.        |
 | 193  | Disk for keeping journal files. About 5 cylinders are         |
 |      | normally required. These files are created automatically by   |
 |      | the server following each update and are named                |
 |      | FATyyjjj FZhhmmss, e.g. FAT90001 FZ120000   |

On CERNVM, the FATMEN service machines are monitored and controlled by the FATONE machine. Any new service machines must be registered by running the FATMEN exec on the 191 disk of this machine, as shown below.

               Modifying the list of FATMEN servers
                                  

defaults list fatmen       /* list current list of FATMEN servers */
FMALEPH FMCNDIVR FMDELPHI FMCHARM2 FML3 FMOPAL FMCPLEAR CPDELPHI
defaults set fatmen fmep03 /* add new FATMEN server */
fatmen (edit               /* edit list of FATMEN servers */
