A Share folder on the NAS cannot be mounted from IBM AIX (error code: 1831-011).

Question:

A Share folder on the Ciphertex NAS can not be mounted from IBM AIX (error code: 1831-011).

Answer:

1. On AIX, type “showmount –e IP_of_NAS” to ensure the directory is actually exported on the NAS.
2. The NAS will do port checking and requires the NFS client to use a reserved port.
    For this situation, type “nfso –o nfs_use_reserved_ports=1” on AIX.
3. If the mount is going to be permanent, On AIX 4.x and 5.1, the command above should be added to the startup scripts. On AIX 5.2 and above, use “nfso –p –o nfs_use_reserved_ports=1”.
