Open System Services NFS Management and Operations Guide

Effect
Attempted operation fails.
Recovery
The recommended action depends on the cause of the error:
If dynamically allocated memory was unavailable, retry the operation after a reasonable
period of time.
If an internal table is full, the only recourse is to perform an operation that makes space
available in the table or to periodically retry the operation until some other operation causes
space to become available.
MNT1 Error 13
Access permission denied. The caller does not have the access permission
necessary to mount a file system.
Cause
An attempt was made to mount a fileset but the current access permissions of the specified mount
point caused the mount attempt to be denied. There are several possible reasons access is
denied:
The mount point was not exported to the caller.
The caller specified a host name to which the mount point was exported, but the host name
was not valid for the specified Internet address of the caller.
Effect
Attempted operation fails.
Recovery
The recommended action depends on the cause of the error:
If the mount point was not exported to the caller, either the caller must change to a netgroup
or host machine to which the mount point is exported or the system administrator must add
the caller to a netgroup to which the mount point is exported.
If the host name specified by the caller does not match any known Internet address for that
host name, the caller must change to a host whose name is recognized.
MNT1 Error 16
Device busy. The specified file system was already mounted.
Cause
There are several possible causes for the device-busy error:
An incorrect object name was specified.
The SERVER object was configured with an incorrect local mount point.
More than one server was configured with the same local mount point and an attempt was
made to start a server with the same local mount point as a server that was already started.
That is, although multiple SERVER objects can be defined with the same local mount point,
only one SERVER object can actually service that mount point.
Effect
Attempted operation fails.
