NFS File Transfer Protocol
NFS allows the ViewStation to perform transparent file access over
the network. The ViewStation dynamically mounts the filesystem and then
transfers the file; it does not use a static mount.
The
HDSware tape may be loaded on any filesystem on any host available to
the ViewStation. There are two ways to handle NFS processes - one for
Sun OS 4.1.x (or BSD types) and one for Solaris 2.x (or Sys V R4.x
types). The NFS functions are the same, but the syntax and file names
are different.
For Sun OS 4.1.x and BSD type UNIX:
To use NFS, you must export the filesystems and/or directories
the ViewStation requires. For example, suppose you loaded the HDSware
tape in the /home/HDS filesystem.
First, verify that the /home/HDS directory is listed in the
/etc/exports file.
If filesystem access needs to be restricted to the
ViewStation, add the ViewStation's name to the access list for the
desired filesystem. For example (in the /etc/ exports file):
/home/HDS -access=hdssun5:hdsfx2
Thus, only hdssun5 and
hdsfx2 have mount privileges to the /home/HDS filesystem. A read-only
flag may also be added for these hosts' access permission. /home/HDS -access=hdssun5:hdsfx2,
ro
Check the transfer block size. The ViewStation uses a
8192 byte block size by default. If 8192 is too large for your network
environment, you must set the correct value in the ViewStation's
configuration file, which is /hds-fx/config/config.fx.
The ViewStation resource is: HDSsetup.NFS.block.size:
8192 (permitted values are 128 to 8192)
Finally, run the command to export the filesystem:
exportfs -a

arguments.
For Solaris 2.x and Sys V R4.x type UNIX:
To use NFS, you must export the filesystems and/or directories
the ViewStation requires. For example, suppose you loaded the HDSware
tape in the /home/HDS filesystem.
First, add this line to the /etc/dfs/dfstab file.
share -F nfs -oro -d "For HDS X Terminals" /home/HDS
Note that this line sets "read-only" permission, and has a
"-d" comment line argument.
Check the transfer block size. The ViewStation uses a 8192
byte block size by default. If 8192 is too large for your network
environment, you must set the correct value in the ViewStation's
configuration file, which is /hds-fx/config/config.fx.
The ViewStation resource is: HDSsetup.NFS.block.size:
8192 (permitted values are 128 to 8192)
Finally, run the command to export the filesystem:
shareall
