Embodiment Construction

[0012] figure 1 is a block diagram of exemplary components of electronic device 100 that can identify software problems. The electronic device may be a computer, such as a storage processor, such as 102 or 132, and may receive and store data from a host server, such as hosts 128 and 158, and retrieve and transmit the data to host servers 128 and 158. 158.

[0013] Storage processor 102 has memory 104 , processor 112 , logic circuitry 120 , and input / output (I / O) unit 126 . Memory 104 has a set of memory locations, some of which are used to store data obtained from memory dump operations in memory sectors 106 . Memory sector 108 is used to store data obtained from OS kernel 118 , and memory sector 110 is used to store consolidated data from memory dump 106 and OS kernel memory 108 . The consolidated data in memory sector 110 may be an overlay of two memory sectors, or it may be a value calculated from various forms of analysis such as may be created by logic circuit 120 . P...

Abstract

Embodiments of the present invention generally relate to including kernel object information in user dumps. Specifically, an improved method of analyzing software problems may include obtaining and storing data elements selected from operating system kernel data prior to performing a memory dump. The method of obtaining the selected kernel data may include creating a thread dedicated to collecting the data and storing it in a memory location for analysis after a memory dump. The operating system kernel data can be analyzed in conjunction with prior art dump data to identify the root cause of software problems.

Description

Background technique [0001] The storage arrays in a data storage system are controlled by storage processors that process data storage and data access requests from host computers. A storage processor is a computer with software designed to process input and output requests from other computers or electronic devices that require access to large memory capacities. [0002] In a storage processor, computer software programs may not always perform exactly as intended, and there may be problems or malfunctions in the software that require correction or correction. Following these guidelines, consider handle leaks that occur because the pool of available file handles is exhausted after the file handle is not returned to the pool after use. The storage handler adds a file handle to the file to simplify handling and tracking the file while it is in the storage handler. When a file is deleted from the storage processor, it is assumed that software in the storage processor causes the...
