Exemplary embodiments of the invention provide a technique to validate physical cabling and logical path before provisioning volume. In accordance with an aspect, a computer comprises a memory storing software and a processor executing the software. The software is operable to: identify first server port and second server port forming redundant ports of a server and first storage port and second storage port forming redundant ports of a storage system; and check whether a redundant relationship is formed by at least one of (i) a physical connection between the first server port and the first storage port and a physical connection between the second server port and the second storage port, or (ii) a logical connection between the first server port and the first storage port and a logical connection between the second server port and the second storage port.

Method and apparatus of redundant path validation before provisioning

A parser uses SAX-like APIs for efficiency and provides DOM-like APIs for simplicity and convenience. The parser can read an XML document, for example, and parse its contents into a set of abstract information containers called nodes. The nodes are used to represent the structure and content of the document, which allows applications to read and manipulate the information in the document while not having to explicitly understand XML syntax. After a document is parsed, the nodes can be explored in any direction; they are not limited to straight-through text file processing.
