Severity: 2-Critical


In few deployment environments, if a device is configured to be part of a device-group before the ASM startup has finished initializing, then it may miss the initial sync from its peer, and not re-request it until another event happens in the system.


The devices are out of sync until another action occurs and the sync is requested again.


Devices are in an auto-sync ASM enabled device-group and a new device is brought into the device-group while initializing the device settings.


Restarting ASM on the affected device or causing another sync event will resolve the issue.
