fdmns - contains file domain names and devices
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 root system 512 Nov 24
18:35 scratch/ drwxr-xr-x 2 root system 512 Nov
24 18:35 usr/
./scratch: total 0 lrwxr-x--- 1 root system 10
Oct 23 15:13 dsk10c@ -> /dev/disk/dsk10c lrwxr-x--- 1
root system 10 Oct 24 11:33 dsk11c@ ->
/dev/disk/dsk11c lrwxr-x--- 1 root system 9 Oct
13 18:29 dsk8c@ -> /dev/disk/dsk8c
./usr: total 0 lrwxr-x--- 1 root system 9 Oct
24 10:52 dsk2g@ -> /dev/disk/dsk2c lrwxr-x--- 1
root system 9 Nov 24 10:35 dsk9c@ ->
/dev/disk/dsk9c
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.
