A method for detecting an un-bootable first computer is described. A failed first computer initiates a boot procedure, and the boot procedure is controlled by boot firmware of the first computer. A virtual interface is established by the boot firmware, the virtual interface having boot status data written therein as the failed computer boots. A second computer reads the boot status data in the virtual interface using a remote direct memory access procedure to access data in the virtual interface. The second computer determines, in response to the boot status data, if the boot procedure of the first computer failed, and if it failed performing a failover routine; and if it succeeded allowing the failed computer to complete its boot procedure. Another connection between the first computer and the second computer is opened, in response to the boot procedure succeeding, using higher level software than the boot firmware. |
