Data Domain: How to Reinitialize and Sanitize SDPM | NVRAM

Applies to:

• DD9910, DD9410, DD6410, DD9910F systems after NVRAM (VOSS) module replacement.
• PowerProtect Data Domain systems that use SDPM on a VOSS module.
• iDRAC Event: SDPM7108 - Critical Diagnostic Event (Sanitize Required)
• All supported Software (DDOS) versions

Required Actions:

Reinitialize the SDPM:

1. Reboot the system
2. Access the system BIOS <F2>: System BIOS > Memory Settings > Persistent Memory
3. Set Sanitize All NVDIMMs to Enabled

3. Set SDPM Memory Size to 32 GB

4. Confirm SDPM sanitization and reboot.

5. Allow the system to reboot to DDOS
6. Verify the SDPM by checking for NVRAM failure alerts and ensuring the file system is enabled.

   • # alerts show current
     -- There should be no outstanding alert relating to the NVRAM subsystem.
     Caution: It may take one to two minutes for the system to clear the NVRAM failure alert.
     
     # system show nvram
     Note: The battery must be at least 80% charged for the file system to start.
     
     # filesys status
     -- The Filesystem should be Enabled & Running

These actions can also be completed in iDRAC:

• Configuration > BIOS Settings > Memory Settings > Persistent Memory
  • Set 'Sanitize All NVDIMMs' to <ENABLED>
    • Ensure 'SDPM Default Memory Size' is set to <32GB>
    • 
  • Select APPLY. Then OK.
  • Select 'At Next Reboot' (Bottom of the page)
• Proceed to reboot the DD unit (e.g. using DD-CLI: #system reboot)
