If the radio buttons for the HA group and devices are grayed out and you cannot select them for readiness check or installation in Cisco Firepower Management Center (FMC), there are a few possible reasons and solutions you can try:
Verify HA Configuration: Ensure that your HA configuration is correctly set up in the FMC. Check that both devices are added to the HA group and their HA status is active.
Verify Device Connectivity: Confirm that both devices are properly connected and reachable from the FMC. Ensure that network connectivity is established between the FMC and the FTD devices.
Check Device Licensing: Ensure that both FTD devices have valid licenses applied. In some cases, if the licenses are expired or not correctly installed, it can cause the devices to be grayed out in the FMC. Verify the licenses and reapply them if necessary.
Check Device Registration: Make sure that both FTD devices are registered with the FMC. If the devices are not registered or have connectivity issues with the FMC, they may appear grayed out. Check the registration status and resolve any registration issues.
Verify FMC and FTD Software Versions: Check that the software versions of the FMC and FTD devices are compatible. Incompatible software versions can cause issues with device management and gray out the radio buttons. Update the software versions if necessary to maintain compatibility.
Review Device Health: Ensure that both FTD devices are in a healthy state. Check the device health status and address any reported issues. If a device is experiencing problems, it may prevent you from selecting it for readiness check or installation.
If you have tried these steps and the radio buttons for the HA group and devices are still grayed out, it may be helpful to review the FMC logs for any relevant error messages.
