Drobo 8D - Enabling or Disabling Dual Disk Redundancy

Drobo 8D User Guide 87
1.5.1 Enabling or Disabling Dual Disk Redundancy
Dual Disk Redundancy protects the Drobo 8D in the event of two simultaneous drive failures.
Although it provides additional protection, it requires more disk space. To learn more about how
much more disk space is required, see Determining Drive Space Requirements.
Note:
Enabling dual disk redundancy will not erase your data.
To use Dual Disk Redundancy, you will need a minimum of three drives. The option will not
be available to you if you do not have a sufficient number of drives or capacity. First, you may
need to Adding Drives.
On enabling Dual Disk Redundancy, Drobo will go through Data Protection (indicated by
yellow and green blinking lights). Do NOT remove the drives or power down the Drobo until
the Drive Bay lights turn solid green.
To enable or disbale dual disk redundancy:
1. In Drobo Dashboard on the All Drobos page, select the Drobo device for which you would like to
enable or disable Dual Disk Redundancy.
2. Click the Drobo Settings option on the Navigation menu, and click General. The General Settings
page opens.
