Issue



 

When attempting a NDMP restore the job fails with an Authentication error after mounting the media.  The same network logon account "ndmp" or "root" used for the restore job is being used for the NDMP backup jobs which complete successfully.

 


Error



 

0xe000fe29 - Authentication failed on connection to the server. Make sure that the user account has the appropriate permissions and that the password was typed correctly. Final error category: Security Errors

 (Also seen following error in some cases)

0xe0009b61 - The logon account that was provided does not have valid credentials. Ensure that the user name and password are correct, and then try again.


Environment



 

Backup Exec 2010/R2/R3

Netapp DATA Ontap Release 7.2.7
Netapp DATA Ontap Release 7.3.2P7

Netapp DATA Ontap Release 8.0.1.
 

 


Cause



 Backup Exec SGMON Debug Log reports the following: 

BENGINE: [ndmp\ndmpcomm]      - ERROR: 4 Error: Connection has not been authorized
BENGINE: [ndmp\ndmpcomm]      - ERROR: sending message 0xf362: not supported.
BENGINE: [ndmp\ndmpcomm]      - ERROR: ndmpSendRequest failed:
BENGINE: [ndmp\ndmpcomm]      - ndmpFreeMessage: message:0x901
BENGINE: [ndmp\ndmpclient]    - getAuthenticationError: ERROR returning: 0x17, 23


Solution



 1) In the restore job properties go to Resource Credentials tab and specify a logon account which has permissions on the filer. By default the logon account is empty when you create a restore job. Specify this account for the NDMP device and all the volumes underneath. Once you specify a logon account for one job, subsequent restore jobs will pickup the same account for the restore.

2) Check the "root" account if it can be used on putty sessions for SSH/Telnet session and successfully log into the Netapp Filer.

3) On the filer add the Backup Exec Media Server to the trusted host file.
   A) Login to the NetApp filer via SSH or Telnet, then on command line enter:
     
   options trusted.hosts hostname1,hostname2,...,newhostname

   NOTE: Please consult the Netapp Data ONTAP System Administration Guide.  No space between the comma and the newhostname.  Newhostname would be the Backup Exec Media Server name or IP.  These settings can also be modified from FilerView (under Security > Configure) or with Netapp System Manager (under Filer > Security > Password/RSH/Trusted Hosts).

 4) Run the NDMP restore job.
