Abstract: A method and apparatus for locating an un-located asset in a computer center including a plurality of assets connected together by a network. The method comprises the steps of host asset of the computer center, obtaining an address for the un-located asset; and sending a command from the host asset to the un-located asset, through the computer center network, for the un-located asset to produce a signal for physically locating the un-located asset. Preferably, the method further comprises the steps of sending a request from the host asset to the un-located asset, through the computer center network, for the un-located asset to confirm that the un-located asset is in the computer center; and in response to receipt of said request, the un-located asset sending a signal to the host asset to confirm that the un-located asset is in the computer center.

Abstract: A system is provided for monitoring signals transmitted over one or more optical serial interface channels in an ESCON environment. A formatter card mounts on bus connector in a general purpose tracing tool (GPT) and intercepts optical I/O signals being transmitted between a host processor and, a peripheral device. The signals are decoded into trace data words which are then partitioned into ESCON transaction frames and mapped into a block of GPT frames. The GPT block is stored on the formatter card and transmitted to the GPT when the GPT can accept the data. Data received by the GPT is interleaved with data from other formatter cards attached to other I/O channels (both ESCON and non-ESCON) and is displayed or printed in time-correlated format for analysis. Data can also be stored for later review.
