Issue



When attempting to browse Network Data Management Protocol (NDMP) filer or NAS resources "An error was encountered while attempting to browse the contents of /vol/vol0. The function is not implemented" is returned in Backup Exec for Windows Servers.


Error



"An error was encountered while attempting to browse the contents of /vol/vol0. The function is not implemented."

The symptoms can be easily identified using an SGMON log, as shown in Figure 3 and Figure 4.
Note: Be sure to start the Sgmon prior to browsing the resource. For information on the Sgmon utility please see Related Documents.

As seen in the Sgmon log, NDMP version 3 is running on the remote filer.

The exact error is seen in the Sgmon log:
       Error : "Call is not supported"
 According to ndmp.org, that error corresponds to: NDMPNotSupported, /* Call is not supported*/ .
 


Environment



With the introduction of Symantec Backup Exec 11d for Windows Servers, the Backup Exec NDMP Option allows the use of the Network Data Management Protocol (NDMP) to initialize and control backups and restores of Network Attached Storage (NAS) devices such as NetApp filers.

This issue can occur when trying to browse an NDMP Filer resource, even though user has installed a valid License Key for the NDMP option and the filer has been successfully added under the NDMP devices tab. (Figure 1 & 2)
