Configure LAN Gateway Functionality

Enable LAN Gateway Functionality for a Single-Node System

You will need to perform the following 2 steps to configure the single-node system as a functioning StorNext LAN Gateway.

Step 2: Add the "diskproxy=server" Mount Option to a Single-Node System

Access the root shell of the system. See Access the System Command Line.
At the prompt, enter the following command to open the /etc/fstab file.
vi /etc/fstab
At the prompt, add the diskproxy=server mount option to the gateway's file system:

CLI Example

snfs1 /stornext/snfs1 cvfs rw 0 0 → snfs1 /stornext/snfs1 cvfs rw,diskproxy=server 0 0

Important

If you are configuring a managed file system, stop the TSM processes before unmounting the file system.

At theprompt, enter the following:
TSM_control stop
At the prompt, enter the following to save the /etc/fstab file:
:wq
At the prompt, enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
At the prompt, enter the following command to verify that the file system is mounted and that the diskproxy=server mount option is present:
/bin/mount
CLI Example Output
/dev/cvfsctl2_snfs1 on /stornext/snfs1 type cvfs (rw,diskproxy=server,sparse=yes)
At the prompt, enter the following command to restart the TSM process, as needed.
TSM_control start

Enable Gateway Functionality for a Dual-Node System

You will need to perform the following 2 steps to configure the dual-node system as a functioning StorNext LAN Gateway.

Step 1: Define the Gateway Interface and Web Hosts for a Dual-Node System

Access the root shell from each node of the system. See Access the System Command Line.
From the primary node, enter the following command to load the configuration file in edit mode:
/usr/cvfs/bin/sndpscfg -e
At the prompt, enter the following to identify the network interface to use as the gateway, making sure to delete the # comment preceding it.
interface bond1 address <interface_IP_address>
CLI Example
interface bond1 address 0.20.86.100
Set tuning parameters, as needed. See the StorNext 6 Tuning Guide.
At the prompt, enter the following command to open the /usr/cvfs/config/sngateway_config file.
vi /usr/cvfs/config/sngateway_config
Within the /usr/cvfs/config/sngateway_config file, do the following to define the server nodes responsible for collecting and processing the gateway metrics values:
1. For the web_service_host_1= value, enter the IP address of the primary node, or of the single-node system.
2. For the web_service_host_2=value, enter the IP address of the secondary node.
Note: You can view the gateway metrics statistics in the Gateway Metrics Report in the StorNext GUI of the host MDC/system.
At the prompt, enter the following to save the /usr/cvfs/config/sngateway_config file:

:wq

At the prompt, enter the following to copy the revised /usr/cvfs/config/sngateway_config file to the secondary node.
scp /usr/cvfs/config/sngateway_config
stornext@<hostname>:/usr/cvfs/config
Note: You need to perform this step because the /usr/cvfs/config/sngateway_config file is not automatically synchronized automatically between the two nodes.

Step 2: Add the "diskproxy=server" Mount Option to a Dual-Node System

Access the root shell from each node of the system. See Access the System Command Line.
From the primary node, enter the following command to open the /etc/fstab file.
vi /etc/fstab
At the prompt, add the following mount option to the gateway's file system:

diskproxy=server

CLI Example

snfs1 /stornext/snfs1 cvfs rw 0 0 → snfs1 /stornext/snfs1 cvfs rw,diskproxy=server 0 0

Important

If you are configuring a managed file system, stop the TSM processes before unmounting the file system.

At theprompt, enter the following:
TSM_control stop
At the prompt, enter the following to save the /etc/fstab file:
:wq
Enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
On the secondary node, enter the following command to open the /etc/fstab file.
vi /etc/fstab
Verify that the diskproxy=server option displays in the /etc/fstab file.
It could take up to 2 minutes for the primary node to synchronize with the secondary node .
Enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
From both nodes, enter the following command to verify that the file system is mounted and that the diskproxy=server mount option is present:
/bin/mount
CLI Example Output
/dev/cvfsctl2_snfs1 on /stornext/snfs1 type cvfs (rw,diskproxy=server,sparse=yes)
From the primary node, enter the following command to restart the TSM process, as needed.
TSM_control start

Disable Gateway Functionality for a Single-Node System

Log on to the single-node system. See Access the System Command Line.
At the prompt, enter the following command to open the /etc/fstab file.
vi /etc/fstab
Remove the diskproxy=server mount option to the gateway's file system.

CLI Example

snfs1 /stornext/snfs1 cvfs rw,diskproxy=server 0 0 → snfs1 /stornext/snfs1 cvfs rw 0 0

Important

If you are configuring a managed file system, stop the TSM processes before unmounting the file system.

At theprompt, enter the following:
TSM_control stop
At the prompt, enter the following to save the /etc/fstab file:
:wq
At the prompt, enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
At the prompt, enter the following command to verify that the file system is mounted and that the diskproxy=server mount option has been removed:
/bin/mount
CLI Example Output
/dev/cvfsctl2_snfs1 on /stornext/snfs1 type cvfs (rw,sparse=yes)
At the prompt, enter the following command to restart the TSM process, as needed.
TSM_control start

Disable Gateway Functionality for a Dual-Node System

Log on to both nodes of a the system. See Access the System Command Line.
From the primary node, enter the following command to open the /etc/fstab file.
vi /etc/fstab
Remove the diskproxy=server mount option to the gateway's file system.

CLI Example

snfs1 /stornext/snfs1 cvfs rw,diskproxy=server 0 0 → snfs1 /stornext/snfs1 cvfs rw 0 0

Important

If you are configuring a managed file system, stop the TSM processes before unmounting the file system.

At theprompt, enter the following:
TSM_control stop
At the prompt, enter the following to save the /etc/fstab file:
:wq
At the prompt, enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
On the secondary node, enter the following command to open the /etc/fstab file:
vi /etc/fstab
Verify that the diskproxy=server option no longer displays.
It could take up to 2 minutes for the primary node to synchronize with the secondary node, after which time the diskproxy=server option should no longer display in the secondary node's fstab file.
Enter the following commands to unmount and remount the file system:
umount /<directory path for file system>
mount <file system name>
CLI Example
umount /stornext/snfs1
mount snfs1
On each node, enter the following command to verify that the file system is mounted and that the diskproxy=server mount option has been removed:
/bin/mount
CLI Example Output
/dev/cvfsctl2_snfs1 on /stornext/snfs1 type cvfs (rw,sparse=yes)
From the primary node, enter the following command to restart the TSM process, as needed.
TSM_control start
