# SDS - Troubleshooting Hunt Group and Ring Group Data Distribution Errors

Symptom | Probable Cause | Solution
Data distribution alarm is generated. Data distribution errors related to resilient hunt groups or ring groups are displayed in the SDS Distribution Errors form. | Remote (secondary) controller does not support hunt group or ring group resiliency. The controller that you have selected as the secondary is not running the required software: 3300 ICP Release 7.0 (or later) for hunt group resiliency or Release 8.0 (or later) for ring group resiliency. | Install the required software on the secondary controller, or select a different controller that is running the required software as the secondary controller. Then, delete the distribution error updates.
Hunt group or ring group already exists on remote (secondary) controller. When you enable resiliency for a group in the Hunt Groups or Ring Groups form, the system adds the group data to the secondary controller. If a group with the same pilot number already exists on the secondary controller, the add group operation fails. | To fix this problem, you must Delete the hunt group or ring group from the secondary controller and then retry the updates from the SDS Distribution Errors form, or Disable resiliency for the hunt group or ring group, delete the corresponding error updates, and leave the two hunt or ring groups separate, or Perform a synchronization of the hunt group or ring group data from the primary controller to the secondary controller.
SDS failed to delete the Remote Directory Number ( RDN) entry for the hunt group or ring group pilot number from the secondary controller's Remote Directory Numbers form. Because the RND entry could not be deleted, SDS could not update the secondary controller with the hunt group or ring group data. | Manually delete the RDN entry for the hunt group or ring group pilot number from the secondary controller's Remote Directory Numbers form. Then, retry the updates from the SDS Distribution Errors form.
Hunt group or ring group member does not exist on (remote) controller. If you add a member to a resilient hunt group or ring group and the directory number of the member is not programmed as a RDN or a device on the secondary controller, the update fails and SDS generates a distribution error. | Log into the secondary controller and program the DN of hunt group or ring group member into the Remote Directory Numbers form. Then, log into the primary controller and retry the updates from the SDS Distribution Errors form.
A new device was added to a resilient hunt group or ring group in the Group Administration Tool. Because the member is not programmed as a RDN on the secondary controller, the update fails and SDS generates a distribution error.
