Configuring NAS server connections (HNAS server only)

Snapshot Administration Guide for Hitachi NAS Platform

Part Number

This utility allows you to specify the VSS connection information for each NAS server or cluster. The utility also displays any NAS server connections that have been configured.

Server connections are configured using the Manage NAS Server Connections utility, shown in this section. You can start this utility during the VSS Hardware Provider installation (by selecting Manage Hitachi NAS Platform connections for VSS provider on the last dialog of the installation program) or after installation through the Windows Start menu.

To configure a VSS connection for a NAS server, specify the information in the Add Connection area (Server Address, Server Port, Supervisor Name, and Password) and click Add. This creates a unique VSS credential (discussed in VSS Credentials), which is saved on the target NAS server and on the VSS host. Once added, the NAS server's IP address or DNS name appears in the Server column of the Server Connections list in this dialog. The Status column lists the status of the VSS credential.



Server Connections

This table lists the DNS name or IP address of all configured NAS servers, along with their status. This table has two columns: Status and Server.

The Server column lists the DNS name or IP address of all NAS servers that have had their connection information specified through this utility (that is, NAS servers for which this host has a VSS credential). If a non-default port number was used when the VSS credential was created, then that number is shown following the server's DNS name or IP address.

The Status column lists the status of the VSS credential. A status is provided only after the server has been tested (by selecting the server and clicking Test). The possible status values are blank (no test run), OK, or Fail.

A status of “Fail” indicates that the VSS host cannot connect to the NAS server. If this occurs, make sure your NAS server is running and that you can PING the server. You can also use the mscfg vss and vss-account CLI commands to ensure that VSS is enabled, and that the NAS server's copy of the credential has not been removed.

Server Address

Specify either the IP address or the DNS name of the NAS server or cluster.

Server Port

Leave blank to use the VSS default port (202). If the server has been configured to use a non-default VSS management port, specify that port number.

Supervisor Name

Specify the name of a management account with supervisor privileges on the NAS server. (The supervisor name is not saved by the VSS Hardware Provider.)


Specify the password of the Supervisor Name provided. (The password is not saved by the VSS Hardware Provider.)


Verifies that the selected server and its VSS credential are still valid. The test establishes a connection to the NAS server's "VSS management server" and sends a loopback message to verify functionality. The test returns either OK or Fail, which is displayed in the Status column.


Removes the selected NAS server's credential. The credential is removed from the VSS host, and, if server connectivity is possible, the credential is also removed from the NAS server.


Displays help information.


Displays version information.


After filling in the fields in the Add Connection area, clicking Add creates a unique VSS credential for the NAS server. The credential is saved on the NAS server and on the VSS host (the system running the VSS Hardware Provider).


After adding one or more connections, clicking OK closes the dialog. While entering information in the Add Connection area, clicking OK steps you through the fields, and pressing Escape on the keyboard closes the dialog.
