E3439 Cmd Rej: Standby TDM in unknown upgrade mode

The TDMs have upgrade phase indicators. The upgrade command expects the disks to be in certain phases before executing a specific action. This message appeared because the standby TDM is not in the correct phase.

Recovery

1. Display the current database status. Enter the act-upgrade:action=dbstatus command.
2. Follow the recovery procedure in the upgrade procedure documentation, or contact My Oracle Support. See My Oracle Support (MOS).
