Troubleshooting an NDMP Internal Error

Description

Backup or restore fails with an internal error.

Cause

NDMP internal errors are indicators of a file system not being

 

accessible or a NAS volume not being available.

Workaround

If the backup application cannot connect to a NAS appliance:

 

1

Log in to the NAS Manager or open a remote terminal to

 

 

the appliance.

 

2

On the NAS Manager, go to Data ProtectionNDMPNDMP

 

 

Configuration page. In NAS CLI, go to Data

 

 

ProtectionNDMPConfiguration menu.

 

3

Verify that NDMP is enabled. If NDMP is enabled, go to step 5.

 

 

– On the NAS Manager, the Enabled check box should be checked.

 

 

– In the NAS CLI, type view and ensure that State is set

 

 

to Enabled.

 

4

If NDMP is not enabled, enable it. For more information, see

 

 

"Backing Up and Restoring Data" on page 114.

 

5

Verify that backup application IP address is configured in NDMP.

On the NAS Manager, the DMA server list should include the IP address of the backup application.

In the NAS CLI, type view and ensure that the DMA Servers list includes the IP address of the DMA application trying to access the NAS appliance.

If the backup appliance can connect to a NAS appliance but cannot log in, use backup_user as the user name for the NDMP client, while setting up the NDMP backup/restore in your backup application. The default password for NDMP client is Stor@ge!
