IPAddress

Mandatory

IP Address of the NFS Server you are importing the shared directory from.

This parameter is mandatory unless the volume was previously mounted with the required syntax, and nfsgy.nlm has not been unloaded after that.

shadowVolume

sys:

Specifies the name of the volume where shadow files are to be stored.

The shadow files are stored in shadowVolume:\gateway directory.

The gateway volume will not be mounted if the specified shadowVolume is not available.

If not specified, the shadow volume specified with the nfsgy command is used.

Do not use the mounted Gateway volumes as ShadowVolume when mounting another volume using gymount. For example, if vol1 is a mounted NFS Gateway volume, then do not execute the following:

gymount vol2 -shadowVolume vol1

IMPORTANT:  Do not dismount or deactivate the volume that shadowVolume points to when NFS Gateway is loaded. Doing so results in deactivation of volumes imported by NFS Gateway.

mountUid

0

UID used for mounting the shared path.

Valid Range: 0 to 2147483647

The NFS Gateway also uses this parameter for UID, when NLM^TM programs running on the server access the NFS Gateway volume with NCP^® Connection Number = 0.

anonUid

55555

UID used for users without a UNIX profile in eDirectory^TM.

Valid Range: 0 to 2147483647

The NFS Gateway also uses this parameter for a user with UID = 0 in the UNIX profile when root access is not given to the NetWare server.

rpcTimeOut

1

Time interval (in seconds) that the gateway waits for a response from the remote server.

Valid Range: 1 to 2147483647

If the network is heavily loaded or remote NFS Server is slow in responding to NFS requests, set a high value for this parameter. You might use a value of 6 seconds which is used by some of the other NFS clients.

If the network is moderately loaded or remote NFS server is fast enough to the responses to NFS queries from NFS Gateway, the default value of one second is sufficient.

We recommend you try a set of values to fine tune this parameter value for your network settings.

dirCompFreq

0

Time (in seconds) after which all the cached shadow file contents for this directory are invalidated.

Valid Range: 0 to 2147483647

The default value of 0 indicates that cache is not invalidated until there is a change in the directory content in the NFS server.

readOnly | readWrite

readWrite

Specifies if the Gateway volume is read-only or read/write.

readSize

32

Specifies the read transfer buffer size in KB.

Valid values = 4, 8, 16, 32

If you enter a value other than 4, 8, 16, or 32 but within the range of 4 - 32, then the lower valid value nearest to the value you enter is used.

For example, if you enter 10, then 8 is used.

If you enter an invalid value outside the range of 4 - 32, the default value is used.

This parameter is applicable only for NFS version 3. If the NFS version is 2, then the value 4 KB is used.

The NFS Gateway checks three values and uses the lowest to determine the actual read size to use. The three values are:

1. Largest UDP Packet Size (Parameter in monitor.nlm > Server Parameters > Communications).
2. The preferred read size as specified by the remote NFS Server
3. The readSize specified on the gymount command.

To ensure that read transfer buffer size is 32 KB of data, ensure that:

• NFS Server has a read preferred size = 32 KB
• Set the NFS Gateway gymount parameter readsize = 32 KB
• Set the largest UDP packet size on NetWare = 33280 (32768 for data +512 for headers)

maxOutstandingPackets

2147483647

Specifies the maximum number of requests to an individual NFS server that can be concurrently outstanding before the NFS Gateway pauses in sending requests to that particular NFS server. An outstanding packet is an NFS request to which no reply has been received, nor has the time out period expired.

For example, if the maxOutstandingPackets = 64, then a maximum of 64 requests can be waiting for a response from an individual NFS server.This is irrespective of the number of Gateway volumes imported from that NFS server. If two or more NFS Gateway volumes are imported from the same NFS server, then the value specified in the first gymount command is used. That value is treated as a pool and shared between the two or more gateway volumes.

If two NFS Gateway volumes refer the same NFS server, then the value specified in the volume mounted first is used between the first and second volume together.

Valid Range: 1 to 2147483647

IMPORTANT:  Use the value of 1 for this parameter with caution because it might negatively impact the performance of the NFS Gateway. The value of 1 means each NFS request must be answered by the remote NFS server before the NFS Gateway sends another request. This increases processing overhead, so use this value only when the network is highly saturated with traffic or when the remote NFS server is unusually slow in responding.

logLevel

1

Specifies the logging level to be enabled for the volume.

0, 1, 2, and 4 are the valid log levels. The values indicate the following:

0 = None (Logging is disabled)

1 = Errors

2 = Warning , Errors

4 = Info, Warning, and Errors

If not specified, the logLevel specified with the nfsgy command is used.
