Abstract
An approach is provided for collecting data for diagnosing a failure of a computer hardware device. After an indication of the failure of the computer hardware device that results in a full system crash is received, an address translation table of a central processing unit (CPU) of the computer hardware device is collected. A format of call stack frames of an operating system (OS) image of the computer hardware device is retrieved. Based on the collected address translation table and the retrieved format of the call stack frames, the call stack frames are retrieved and output to a computer file. Retrieving the call stack frames is performed by a service processor external to system processing units running OS images via a hypervisor of the computer hardware device. The service processor does not require an ambulance logical partition managed by the hypervisor.
