fdmns(4)fdmns(4)NAMEfdmns - contains file domain names and devices
The fdmns directory ensures access to file domains by providing sym‐
bolic 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 direc‐
tory 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 sys‐
tem 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.
