Last Modified: Feb 17, 2021

Bug Tracker

Affected Product:  See more info
BIG-IQ DNS(all modules)

Known Affected Versions:
5.4.0, 5.4.0 HF1, 5.4.0 HF2

Opened: Feb 04, 2021
Severity: 3-Major

Symptoms

BIG-IQ checks 7 pieces of information to determine if a DNS sync group is healthy or not. One of the pieces of information is broken due to a BIG-IP known issue. In the Devices -> BIG-IP Clusters -> DNS Sync Groups UI, the sync group status is shown as "Waiting for initial data collection"

Impact

This may give the user false positive status information.

Conditions

BIG-IQ manages BIG-IP devices running version 14.x.x or 16.x.x.

Workaround

Use the following three steps to double check if the DNS_Sync_Group is healthy or not. 1: Use the Rest API to check and find out what is not healthy: GET https://{big-IQ}/mgmt/cm/dns/current-config/sync-group-health/{ID} Due to this bug, you will notice the information below in the response. { ... "code": "DEVICE_SERVICE", "color": "BLUE", "message": "Waiting for initial data collection" ... } 2. Go to the BIG-IP device and check if the following 4 services are running: "mcpd", "gtmd", "big3d", "tmm" For example, using the following Linux shell command shows the mcpd is running: # bigstart status |grep mcpd mcpd run (pid 7077) 233 days 3. If all 4 services are running on BIG-IP, it suggests that the issue reported is a false positive, and no action needs to be taken.
