Save Redundant Gateway Pair Configuration

Whenever configuration changes are made to the VMA SAN Gateway, always save the

configurations so they will be persistent. This can be performed using either the VMA SAN Gateway

CLI interface or the web interface:

• If using the CLI interface, issue the ‘write memory’ command

• If using the web interface, click on the red ‘Commit Changes’ button at the top center of the

window.

Backup the Redundant Gateway Pair Configuration

It is also recommended for disaster recovery of the VMA SAN Gateway configuration file, that you

create a copy of the gateway configuration file and upload it to a production or maintenance server

to be included in the regular data backup of that server. When required to recover the gateway

configuration file you can restore it to the server and then from the gateway issue a ‘fetch’ to

retrieve it back to the gateway. You only need to backup the active gateway configuration of the

gateway currently showing ‘master’ status.

First create a copy of the current active configuration on the ‘master’ VMA SAN Gateway to a

configuration file, using the configuration write command:

# configuration write to <file-name>

Next step is to copy the saved gateway configuration file to the production or maintenance server

using the configuration upload command so that it can be included in regularly scheduled

data backups:

# configuration upload <file-name> scp://<user-login>[:<password>]@<server

IP>/<target-directory>[/<file-name>]

When required to recover the gateway configuration file, you can retrieve the restored configuration

file from the production or maintenance server by issuing the configuration fetch command:

# configuration fetch scp://<user-login>[:<password>]@<server-IP>/<source-

directory>/<source-file-name> [<gateway-file-name>]

After the gateway configuration has been ‘fetched’, activate the restored configuration with the

‘configuration switch-to’ command as follows:

# configuration switch-to <file-name>

Configure connected Host Servers

After the pairing process of the redundant pair VMA SAN Gateways, connected Host servers must

be configured to use multi-pathing (a.k.a. MPIO) across FC links to both paired gateways in order to
