NAME

fdmns − contains file domain names and devices

DESCRIPTION

The fdmns directory ensures access to file domains by providing symbolic links to every volume in the file domain.  The mkfdmn, rmvol, and addvol utilities automatically manage the fdmns directory.  Each file domain is described by its own subdirectory within the fdmns directory. 

Back up the fdmns directory structure regularly using the vdump utility or any other backup utility (dump, tar, cpio). If the contents of the fdmns directory are deleted or corrupted, restore the directory from your most recent backup tape.  You must also restore the fdmns directory after installing a new version of the operating system. 

Always keep a hardcopy record of each file domain and its associated volumes in case a backup copy of the fdmns directory is unavailable. If you have a record, you can reconstruct the fdmns directory structure. The following is a sample fdmns directory:

total 2
drwxr-x---2 rootsystem512 Nov 24 18:35 scratch/
drwxr-xr-x2 rootsystem512 Nov 24 18:35 usr/
 ./scratch:

lrwxr-x---1 rootsystem10 Oct 23 15:13 dsk10c@ -> /dev/disk/dsk10c
lrwxr-x---1 rootsystem10 Oct 24 11:33 dsk11c@ -> /dev/disk/dsk11c
lrwxr-x---1 rootsystem 9 Oct 13 18:29 dsk8c@ -> /dev/disk/dsk8c
 ./usr:
total 0
lrwxr-x---1 rootsystem 9 Oct 24 10:52 dsk2g@ -> /dev/disk/dsk2c
lrwxr-x---1 rootsystem 9 Nov 24 10:35 dsk9c@ -> /dev/disk/dsk9c

RESTRICTIONS

Do not remove or modify the contents of this directory. If the fdmns file becomes corrupted, you can no longer access (or mount) any fileset in the file domains.
