During some system reboots, the OS is loaded from the storage device to the host memory. If the device on which the OS image resides is remote and needs to be accessed through network connections using a Niantic NIC HBA, you might see the following error message:
Timeout waiting for Tx completion 10G full duplex link up. Link down, restarting network initialization 10G full duplex link up. Timeout waiting for Tx completion 10G full duplex link up
In this case, the OS will not be avaialble.
Recovery: If you see the preceding messages, issue a "send break" as describe in ILOM documentation at: Oracle ILOM User’s Guide for System Monitoring and Diagnostics Firmware Release 3.2.x.
The host console should drop to the OBP prompt, and at the OBP prompt, you can issue the "reset-all" command.
Workaround: This issue occurs intermittently, and the root cause is still under investigation. If you encounter this it, contact your authorized Oracle Service provider to see if a fix is available.
