IBM General Parallel File System for AIX: Data Management API Guide

Functions that provide a file handle as an input argument

[EINVAL]

The format of the file handle is not valid.

Note:

This error is returned without attempting to locate any object that is referenced by the handle. The EINVAL error code is to be distinguished from the EBADF error code, which, as specified in the XDSM standard, indicates that the object does not exist or is inaccessible. Thus, GPFS provides a refinement, distinguishing between format and access errors related to handles.

[EPERM]

DMAPI is disabled for the file system that is referenced by the file handle.
