Summary

Configuration needed to perform a NDMP backup of an EMC Isilon with DPX.

 

Symptoms

OneFS prevents NDMP backups by default. Before you can perform NDMP backups, you must enable NDMP backups and configure NDMP settings.

 

Resolution

    Login to OneFS UI management and follow the instructions below 1 to 7

 

  1. Click Data Protection > Backup > NDMP Settings.
  2. In the Service area, click Enable.
  3. Next specify a port through which data management applications (DMAs) access the cluster, or the DMA vendor that OneFS is to interact with, in the Settings area.  Click Edit settings.
    1.  In the Port number field, type 10000.
    2.  From the DMA vendor list, select generic.
  4. Click Add administrator to add an NDMP user account through which your DMA can access the cluster.
    1. In the Add Administrator dialog box, in the Name field, type a name for the account.
    2. In the Password and Confirm password fields, type a password for the account.
    3. Click Submit.
  5. On the NDMP Proxy server, you will need to modify the SSNDMPC registry key so we can communicate to the EMC Isilon using v3 of the NDMP protocol. You need to set it to v3 since the EMC Isilon doesn’t respond properly to all of the v4 commands.
    1. HKEY_LOCAL_MACHINE\SOFTWARE\Syncsort\BackupExpress\ <NDMP Proxy Server Name Here>\0\SSNDMPC
    2. Your data Value may read: --filehistory=local --loglog
    3. Change it to read: --filehistory=local --loglog -xpmax 3
  6. After making this change, you need to cycle the DPX Cmagent agent on NDMP Proxy server
    1. Note: This should be a unique NDMP proxy server not used for any other backups.
  7. Add the EMC Isilon to the DPX enterprise.
    1. From the DPX home page, select Configure > Enterprise.
    2. Select the enterprise, and then select the Node Group to which you want to add the Data Mover. Click Add Node.
    3. When the page refreshes, type the Logical Node Name, Resolvable Node Name or IP address, Client node, Port 10000, User Name, and the Password that you created under steps 3 and 4.
    4. Click TEST to verify that the correct authentication with the Data Mover, and click Apply.
