NAME
servers - map server names to numbers

DESCRIPTION
Each file server has a file, /vice/db/servers, which maps server names to numbers. The server numbers are 8 bit numbers so a maximum of 256 servers can be supported. Once a server number has been assigned, it may not be reused. You should not reassign a server a new id without initializing the server. The server numbers are used in too many places, probably the most important is in the creation of volumes. The server creating a volume uses its server number as the first byte of the four-byte volume identification number in order to ensure uniqueness. NOTE: Replicated volume numbers must also be unique, so we reserve part of the range, 0-127 (0-7F hex), for this purpose. Real server numbers must not be allocated from the other subrange, and vice-versa. The format of the file is the full server name (e.g. mahler.coda.cs.cmu.edu) followed by a tab and then the servers number. Any line beginning with a " is considered a comment and is ignored. The following is an example servers file:

MAHLER.CODA.CS.CMU.EDU          201
GRIEG.CODA.CS.CMU.EDU           204
HAYDN.CODA.CS.CMU.EDU           205
WAGNER.CODA.CS.CMU.EDU          206
DEBUSSY.CODA.CS.CMU.EDU         212
SCARLATTI.CODA.CS.CMU.EDU       214
ROSSINI.CODA.CS.CMU.EDU         215
PUCCINI.CODA.CS.CMU.EDU         216
GERSHWIN.CODA.CS.CMU.EDU        218
SCHUMANN.CODA.CS.CMU.EDU        219

FILES
/vice/db/servers

BUGS
The server numbers and replicated volume prefixes are pulled from the same number space. Separation is enforced only by convention. This file and /vice/db/hosts should be combined.
