Configuring a Distributed LAN Client Server

To configure a StorNext client as a distributed LAN client, edit mount options in the /etc/fstab file.

1Stop the StorNext client. At the command prompt, type:

/etc/init.d/cvfs stop

2Configure the client to mount a file system as a distributed LAN client. To do this, edit the /etc/fstab file so that it contains the following line:

<file system> <mount point> cvfs rw,diskproxy=client 0 0

where <file system> is the name of the StorNext file system and <mount point> is the directory path where the file system is mounted.

3Start the StorNext client. At the command prompt, type:

/etc/init.d/cvfs start

To configure a StorNext client as a distributed LAN server, edit mount options in the /etc/fstab file, and then configure distributed LAN server options.

1Stop the StorNext client. At the command prompt, type:

/etc/init.d/cvfs stop

2Configure the client to mount a file system as a distributed LAN server. To do this, edit the /etc/fstab file so that it contains the following line:

<file system> <mount point> cvfs rw,diskproxy=server 0 0

where <file system> is the name of the StorNext file system and <mount point> is the directory path where the file system is mounted.

3Change to the /usr/cvfs/bin/ directory.

4Launch the StorNext distributed LAN server configuration utility. At the command prompt, type:

./sndpscfg -e

Note: To get help for the sndpscfg utility, at the command prompt, type: ./sndpscfig -h

The distributed LAN server configuration utility appears (figure 36).
