Cause

There was a typo and the Default network settings during the initial deployment. The post configuration for the Default Network has validation for the DNS server entries, but the initial deployment does not do a validation. The validation is failing on the typo and not allowing the settings to be changed.

Resolution

The DNS Servers may be updated using the PowerProtect /usr/local/brs/puppet/manifests/extdata/common.json configuration file. Ensure that there are no backups or restore jobs running in the environment as it requires a PowerProtect Appliance reboot to apply the changes.

  • Validate there are no active backups or restore sessions.
  • Open an SSH session to PowerProtect Data Manager and authenticate with the admin account.
  • Confirm the current settings of the common.json configuration file: cat /usr/local/brs/puppet/manifests/extdata/common.json
  • Open the common.json configuration file and edit the dnsServers values: vi /usr/local/brs/puppet/manifests/extdata/common.json

command output 

  • Confirm the current settings of the common.json configuration file: cat /usr/local/brs/puppet/manifests/extdata/common.json
  • Restart the PowerProtect Appliance: sudo reboot
  • Allow the PowerProtect Appliance to fully initialize
  • Confirm that the Default network settings were properly updated.
