Techniques are provided for processing an Input/Output (I/O) request. At least one data block is allocated for use in completing the I/O request. A current operations record is stored for the I/O request. It is determined whether the I/O request has been completed within a specified period of time. In response to determining that the I/O request has not been completed within the specified period of time, the allocated at least one data block is fenced.

Fencing of resources allocated to non-cooperative client computers

A mechanism is provided for a failed computer system to send a report of the failure to a remote site without dependency on a service processor or maintenance processor. The computer system is capable of reporting system failure to a remote site independent of whether the system may be successfully rebooted. The system includes a CPU, and, coupled to the CPU, a non-volatile control store, a main memory, a storage device storing a computer operating system, and a data modem. Firmware is resident in the non-volatile control store of the main computer system for reporting system failure to a remote site independent of whether the system may be successfully rebooted by reloading the operating system into main memory. The firmware is invoked upon occurrence of a non-recoverable error and provides for assembling failure-related information, establishing communication with the remote site, and transmitting the failure-related information to the remote site.
