Opened: Aug 12, 2020

Severity: 2-Critical

Symptoms

Sometimes, when vCMP guests or F5OS tenants are started after the host has been upgraded, the guests or tenants may enter an unhealthy state due to clusterd constantly restarting.

Impact

-- This issue might prevent the guest or tenant from servicing traffic if the system fails to load the config and clusterd keeps restarting. -- During startup of the guest or tenant, the following message is logged to /var/log/ltm: err mcpd[6519]: 0107146f:3: Self-device state mirroring address cannot reference the non-existent Self IP ([IP address]); Create it in the /Common folder first. -- /var/log/ltm shows clusterd constantly restarting. -- One or more slots are in INOPERATIVE state, while the host shows slots as RUN/Healthy.

Conditions

-- vCMP guest or F5OS tenant has Mirroring IP configured. -- vCMP guest or F5OS tenant is powered on after vCMP host upgrade. -- vCMP guest or F5OS tenant is powered on and receives a new license file from the host during startup.

Workaround

-- To avoid the issue before it occurs: 1. Prior to shutting down vCMP guests or F5OS tenants before host upgrade, ensure guests or tenants have free space in the /var partition. 2. Ensure any license updates (e.g., reactivation) are applied before shutting down the vCMP guest or F5OS tenant. 3. Issue 'tmsh save sys config' on the vCMP guest or F5OS tenant. 4. Issue 'ls /var/db/mcp*' and confirm the presence of mcpdb.bin and mcpdb.info in the /var/db directory. 5. Proceed with vCMP guest or F5OS tenant shutdown and host upgrade as per standard F5 recommended process. -- To mitigate after the issue has been experienced on a vCMP guest or F5OS tenant: 1. Set the vCMP guest or F5OS tenant to the Configured state and wait for it to complete transition to Configured. 2. Set vCMP guest or F5OS tenant to Deployed state. 3. Review startup logs and confirm 'Self-device state mirroring address cannot reference the non-existent Self IP' message is no longer present. 4. Review /var/log/ltm and confirm clusterd is no longer restarting. 5. If issue persists, delete and recreate the vCMP guest or F5OS tenant.
