This topic provides information on the parameters
in the NFS Gateway Mount Parameters page. The parameters are available in
the following tabs:
General
NFS/RPC
Log
Additional
Server Name
Displays the name of the server.
NFS Gateway Status
Indicates the NFS Gateway status, which can be Running or Stopped.
Volume Name
Name of the volume that you are mounting. Range: 2 to 15 characters.
The volume name is mandatory when you are mounting a new volume.
You can view and modify
the volume name when editing a dismounted volume. However, you cannot modify
this field when editing a mounted volume; you can only view the volume name.
Remote IP Address/Hostname
The IP address or hostname of the NFS server from where you are importing the shared directory.
The remote IP address or hostname is mandatory if you are mounting the volume for the first time after the NFS Gateway is loaded.
You can view and modify the remote IP address when editing a dismounted volume. However, you cannot modify this field when editing a mounted volume; you can only view the remote IP address/hostname.
Remote Path
The absolute path of the shared directory in the NFS server.
The remote path is mandatory if you are mounting the volume for the first time after the NFS Gateway is loaded.
You can view and modify the the remote path when editing a dismounted volume. However, you cannot modify this field when editing a mounted volume; you can only view the remote path.

of shared paths on the remote server.
Volume entry in gystart.ncf
Specifies whether to add the mounted volume to the gystart.ncf. Default = Unchecked (not added). If unchecked, the volume is only mounted but not added to the gystart.ncf.
Code Page
Specifies the code page in which the files are created/accessed on the NFS Gateway volume. This should ideally match the code page of your client system. If you leave this field as blank, the default code page of your NetWare server will be used.
NFS Version
Specifies the NFS protocol version the volume is imported
over. The valid values available in the drop-down list are 2 or 3. Default
= 3.
We recommend using NFS version 3 because the NFS Gateway is optimized for
this.
You can view and modify the NFS version when editing a dismounted volume.
However, you cannot modify this field when editing a mounted volume; you can
only view the NFS version.
If NFS version 3 is not supported by the NFS Server, then the volume is mounted with NFS version 2.
Read Size
Specifies the read transfer buffer size in KB. Valid values = 4, 8, 16, 32. Default = 32.
If you enter a value other than 4, 8, 16, or 32 but within
the range of 4 to 32, 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 any invalid value
the default value of 32 KB is used.
This parameter is applicable only for NFS version 3. If the NFS version is 2, then a value of 4 KB is used.
The least value among the largest UDP packet size (Parameter in monitor.nlm > Server Parameters > Communication) set on NetWare, NFS Server read preferred size and the readsize is used for read transfer.
To ensure that the read transfer buffer size is 32 KB of data:The read size value used for RPC calls depends on the maximum UDP packet size defined by the system and the preferred read size of the NFS server. Therefore, the read size in use might differ from the value given by the user.
Write Size
Specifies the write transfer buffer size in KB. Valid values = 4, 8, 16, 32. Default = 32
If you enter a value other than 4, 8, 16, or 32 but within the range of 4 to 32, 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 any invalid value, the default value of 32 KB is used.
This parameter is applicable only for NFS version 3. If NFS version 2 is specified, then a value of 4 KB is used.
The least of value among the largest UDP packet size(Parameter in monitor.nlm > Server Parameters > Communication)set on NetWare, NFS Server write preferred size and the writesize is used for write transfer.
To ensure that write transfer buffer size is 32 KB of data:
The write size value used for RPC calls depends on the maximum UDP packet size defined by the system and the preferred write size of the NFS server. Therefore, the write size in use might differ from the value given by the user.
Max Outstanding Packets
Specifies the maximum number of outstanding packets to
a UNIX* machine. This value is for a UNIX machine or NFS server irrespective
of the number of Gateway volumes mounted. Range: 1 to 2147483647. Default
= 8.
For example, if the maxOutstandingPackets = 64, then a maximum of 64 requests will be waiting for a response from the NFS server. If two NFS Gateway volumes refer the same NFS server, then the value specified in the volume mounted first is shared between the first and second volume.
The actual value of maxOutstandingPackets for RPC calls vary according to network behavior, with the value given by the user taken as the maximum value.
Mount UID
The UID used for mounting the shared path. Range: 0 to 2147483647. Default = 0.
The NFS Gateway also uses this parameter for the UID, when NLM programs running on the server access the NFS Gateway volume with the NCP Connection Number = 0.
Mount GID
The GID used for mounting the shared path. Range: 0 to 2147483647. Default = 1.
Anon UID
The UID used for users without a UNIX profile in eDirectory. Default = 55555. Range: 0 to 2147483647. The gateway also uses this parameter for the user with UID=0 in the UNIX profile when root access is not given to the NetWare® server.
Anon GID
The GID used for users without a UNIX profile in eDirectory. Default = 55555. Range: 0 to 2147483647.
Force Anon Uid/Gid
Specifies whether to force all NFS requests to go with Anon UID and Anon GID. Default = Unchecked (not enforced).
RPC Timeout
The time interval (in seconds) that the Gateway waits for a response from remote server. Range: 1 to 2147483647. Default = 1.
If Dynamic RPC Timeout is enabled, then the actual timeout value used for RPC calls varies according to network behavior, with the value given by the user taken as the minimum value.
RPC Retries
Number of times each RPC request is retried, if the reply
for a request does not come within the rpcTimeOut period.
Range: 1 to 2147483647. Default = 3.
With every RPC retry, the value of the rpcTimeOut for that packet is doubled. For example, if the rpcTimeOut is set as 1, then in the second attempt of RPC request, the value of rpcTimeOut doubles to 2.
Dynamic RPC Timeout
Specifies whether to dynamically set RPC timeouts based on network behavior. Default = Checked (Dynamic RPC timeout is enabled).
Dynamic MOP
Specifies whether to dynamically set the value of MOP (Max Outstanding Packets)based on network behavior. Default = Unchecked (Dynamic MOP is not enabled).
Log Level
Specifies the logging level to be enabled for the volume. Default = 1 (Errors).
0, 1, 2, 4, and 8 are the available log levels in the drop-down list. The
values indicate the following:
0 = None
1 = Errors
2 = Warning, Errors
4 = Info, Warning, and Errors
8 = Debug, Info, Warning, and Errors
The logLevel = 8 is not recommended in typical cases. Use this only
for debugging purposes.
If a logging level is not specified here, the logLevel specified with the
nfsgy is used.
Log Verbose
Specifies whether to log verbose information. Default = Unchecked (Disabled).
If log verbose is not specified here, the value specified with the nfsgy is used.
Shadow Volume
Specifies the name of the volume where shadow files are
to be stored. The shadow files are stored in shadowVolume:\gateway directory.
The NFS Gateway does not load if the volume specified is not available. If
shadow volume is not specified here, the shadow volume specified with the
nfsgy is used.
Dir. Comp. Frequency
Time (in seconds) after which all the cached shadow file contents for this directory are invalidated. 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.
Umask
File mode creation mask for files and directories created from the NFS Gateway. Default = 022. Valid Range: 000 - 777. This value must be octal.
Read Only
Specifies if the gateway volume is read-only or read/write. Default = Unchecked (Read/Write is enabled).
Toss Metadata
Invalidates or retains file metadata immediately after the file is closed. Default = Unchecked (noTossMetadata or retain is enabled).
Lowercase UNIX names
Forces the file or directory created from NetWare to have lowercase filenames on UNIX. Default = Unchecked (Not enforced).
Show Dot Files
Specifies whether or not to show the dot files (beginning with dot(.)) of the remote machine. Default = Checked ( Dot files are displayed).
OK
Saves the parameter changes you make.
Refresh
Refreshes this user interface with the volume parameters from the NFS Gateway back end and shared path list from the remote server.
Cancel
Discards the changes and returns to the NFS Gateway mounted volumes page.
