Open System Services NFS Management and Operations Guide

There are several possible reasons why access is denied:
• The permissions kept by the NFS file system do not allow the caller to access the file.
• The security attributes do not allow the caller to access the file.
• The file type is not a type supported by the OSS NFS subsystem (for example, an SQL table).
Effect
Attempted operation fails.
Recovery
The recommended action depends on the cause of the error:
• If access is denied because of the NFS access permissions, either the caller must change
to a user ID that is recognized as valid for accessing the file, or the NFS access permissions
must be changed (by a user with appropriate permission) to allow the caller access.
• If access is denied because of security settings, either the caller must change to a user ID
that is recognized as valid for accessing the file or the security settings must be changed
(by a user with appropriate permission) to allow the caller access.
NFS2 Error 16
Device busy. The caller attempted to remove a directory while the
directory was in use.
Cause
An attempt was made to remove a directory on which another fileset is mounted.
Effect
Attempted operation fails.
Recovery
Corrective action is application-dependent. First, the pathname and directory structure should
be examined to ensure that the pathname is correct. If the pathname is incorrect, correct the
pathname and retry the operation. If the pathname is correct, the fileset mounted on the specified
directory must be unmounted before the directory can be removed. Filesets should be unmounted
only when absolutely necessary, because unmounting a fileset makes all directories and files
within that fileset inaccessible.
NFS2 Error 17
File exists. The specified file already exists.
Cause
An operation was attempted that assumed the absence of a particular file when, actually, the
file was present.
Effect
Attempted operation fails.
Recovery
Corrective action is application-dependent. Either retry the operation using the name of a file
that does not exist or, prior to retrying the operation, delete or rename the existing file.
NFS2 Error 19
No such device. The caller attempted to perform an operation on a
nonexistent device or to perform an illegal operation on a valid device.
Cause
Either an attempt was made to perform an operation on a device that does not exist or the
attempted operation is illegal on the specified device (such as a write operation to a read-only
device).
