Systems, methods and a computer program product are provided to permit the identification of all of the devices of a specified domain in a multi-domain environment. All communication among the domain devices is in-band having the advantage that no additional cabling is required. A control center between host devices and the domains receives an in-band command from an initiating device in a specified domain, the command being transmitted in response to the activation of a triggering device on the initiating device. Upon receipt of the command, the control center broadcasts an in-band command to each of the other devices in the domain directing the other devices to activate an indicator on each of the other devices. With the indicators on the devices in the specified domain activated, an administrator is able to identify those devices and thus focus his search for the faulty device only on those devices within the domain.

An apparatus, system, and method are disclosed for bad block remapping. A bad block identifier module identifies one or more data blocks on a solid-state storage element as bad blocks. A log update module writes at least a location of each bad block identified by the bad block identifier module into each of two or more redundant bad block logs. A bad block mapping module accesses at least one bad block log during a start-up operation to create in memory a bad block map. The bad block map includes a mapping between the bad block locations in the bad block log and a corresponding location of a replacement block for each bad block location. Data is stored in each replacement block instead of the corresponding bad block. The bad block mapping module creates the bad block map using one of a replacement block location and a bad block mapping algorithm.

A headless computer entity having a plurality of disk drives operates to self restore to a known state, upon failure of either a system disk drive containing an operating system of the computer entity, or failure of a data disk drive containing application data. Depending upon whether the system disk and / or the data disk are replaced by a replacement disk, the computer entity configures itself with either deletion of application data on the data disk, or with deletion of application data on both the system disk and the data disk. The computer entity determines whether a new replacement disk has been installed by comparing a signature of the system disk with a signature of the data disk. If a replacement disk is detected, then the digital signatures are set by the computer entity such that the system disk and data disk have a self consistent set of hardware specific digital signatures. Application data is returned to a known good state after deletion.

An aspect of the present invention simplifies the implementation of custom atomic transactions. A program logic (implementing a custom atomic transaction) may request a unique transaction identifier from a programming environment. The program logic may then specify a task procedure, corresponding roll-back procedures, and the transaction identifier using an interface provided by the programming environment. The programming environment keeps track of the specified roll-back procedures. The information maintained by the programming environment may be used to execute the roll-back procedures if the atomic transaction is to be aborted. As the programming environment keeps track of the roll-back procedures to be executed, the implementation of atomic transactions may be simplified.

Techniques to ascertain physical cabling connections of electronic systems are provided for situations where there are numerous systems interconnected by a very large number of electrical or optical cables. A cable identifying code is inserted into a message sent from a local endpoint system to remote endpoint system over the identified cable. Each intermediate system that is in the interconnection path between the two endpoint systems of interest appends its code for the cable connected to the I / O port from which the message will egress that system and be sent to the next system along the path. The remote endpoint system receives the message which now contains codes for all the cables transited along the path, extract the codes, and thereby determines the exact cabling used in the interconnection of the two endpoint systems.
