Abstract
A computer implemented method, apparatus, and computer program product for obtaining an absolute path name for an open file system object. A file descriptor for the open file system object is identified in response to a process in a first software partition opening a file system object to form the open file system object. The absolute path name for the open file system object is cached in a path name field in a file structure associated with the file descriptor for the open file system object. The absolute path name for the open file system object in the path name field is used during migration of the first software partition to restore the open file system object in a second software partition.
