Question

Error

Vmount:operation not permited

Answer

--------------------------------------------------------------------------------

Environment

AIX versions 4.x and 5.x

Sometimes Linux NFS servers would do port checking and require, the NFS client use a reserved port.

Nfso-o Nfs_use_reserved_ports=1

If The mount is going to being permanent, then the change needs to survive across a reboot. The NFS option must be changed permanently. On AIX 4.x and 5.1, the command above should is added to the startup scripts (POSSIBLY/ETC/RC.NFS). On AIX 5.2 and above, the change can is made permanent by adding THE-P flag.

Nfso-p-O Nfs_use_reserved_ports=1
