Symptome

Network Data Management Protocol (NDMP) is a protocol used to control data backup and recovery communications between primary and secondary storage in a heterogeneous network environment. This article lists common NDMP error codes and messages that may be encountered during NDMP operations on Network Attached Storage (NAS) hardware. These error codes do not come from the backup application, but are from the NDMP protocol directly. They may appear in backup logs but are messages that are sent from the NAS to the backup solution over the NDMP protocol.

 

 

Note: The list provided below is not all-inclusive and may not cover every possible NDMP protocol error.

 


NDMP Error Codes and Descriptions

Code Description
NDMP_DEVICE_BUSY_ERR The specified drive or hardware is already in use.
NDMP_DEVICE_OPENED_ERR NDMP is attempting to open more connections than are allowed.
NDMP_NOT_AUTHORIZED_ERR This error is returned if an NDMP request is issued before the connection has been authenticated.
NDMP_PERMISSIONS_ERR The connection has been authenticated, but the credentials used lack the necessary permissions.
NDMP_DEV_NOT_OPEN_ERR An attempt was made to access the NDMP protocol without first opening a connection to it.
NDMP_IO_ERR A drive has returned an input or output (I/O) error when attempting to read or write to or from the NAS.
NDMP_TIMEOUT_ERR The current operation has timed out.
NDMP_ILLEGAL_ARGS_ERR The request contains an illegal argument.
NDMP_NO_TAPE_LOADED_ERR There is no tape in the drive.
NDMP_WRITE_PROTECT_ERR The NAS hardware or drive is write protected.
NDMP_EOF_ERR An unexpected end of the file was encountered.
NDMP_EOM_ERR The tape or destination drive has run out of space (the End of Media Mark was encountered).
NDMP_FILE_NOT_FOUND_ERR The requested file was not found.
NDMP_BAD_FILE_ERR A bad file descriptor generated an error.
NDMP_NO_DEVICE_ERR A request was made to a tape drive that does not exist.
NDMP_NO_BUS_ERR The specified SCSI bus cannot be found.
NDMP_NOT_SUPPORTED_ERR Either the NDMP protocol is not supported, or only a subset of the protocol is supported.
NDMP_XDR_DECODE_ERR A message cannot be decoded.
NDMP_ILLEGAL_STATE_ERR A request cannot be processed in its current state.
NDMP_UNDEFINED_ERR A nonspecific error has occurred.
NDMP_XDR_ENCODE_ERR There was an error encoding a reply message.
NDMP_NO_MEM_ERR

There was an error due to memory allocation on the NAS hardware.
NDMP_DATA_HALT_INTERNAL_ERROR

Error signifies that an internal NAS issue caused the data operation to unexpectedly stop.

 

Ursache

The NDMP service running on the NAS hardware generates the NDMP error codes listed above. These errors indicate various issues that can occur during the backup or recovery process. For example, when an NDMP operation on NAS hardware fails with the error code NDMP_NO_MEM_ERR, it indicates that the NDMP service encountered a memory allocation error. This could be due to insufficient system resources or memory leaks within the NDMP service on the NAS device.

Lösung

If you encounter an NDMP error, follow these steps:

  1. See the error code descriptions to understand the nature of the issue.
  2. Perform initial troubleshooting based on the error code received.
  3. If the issue persists, contact the vendor of your NAS device for further assistance.

The hardware vendor’s support team has the necessary expertise and resources to help resolve the issue.
