NFS Services Administrator's Guide (B.11.31.04) March 2009

Table 2-6 NFS client daemons
FunctionDaemon Name
Supports record lock and share lock operations on the NFS files.
rpc.lockd
Maintains a list of clients that have performed the file locking operation
over NFS against the server. These clients are monitored and notified in
the event of a system crash.
rpc.statd
Following are the tasks involved in configuring and administering an NFS client.
• Configuring the NFSv4 Client Protocol Version (Optional)
• “Deciding Between Standard-Mounted Directories and Automounted Directories”
(Required)
• “Enabling an NFS Client ” (Required)
• “Mounting Remote Directories ” (Required)
• “Changing the Default Mount Options” (Optional)
• “Unmounting (Removing) a Mounted Directory” (Optional)
• “Disabling NFS Client Capability” (Optional)
Configuring the NFSv4 Client Protocol Version
IMPORTANT: The nfsmapid daemon must be running on both the NFS server and
the client to use NFSv4. For more information on how to configure the NFSv4 server
protocol version, see “Configuring the NFSv4 Server Protocol Version ” (page 29).
By default, the version of the NFS protocol used between the client and the server is
the highest one available on both systems. On HP-UX 11i v3, the default maximum
protocol version of the NFS server and client is 3. The default minimum protocol version
of the NFS server and client is 2.
To configure the NFS client to enable it to mount filesystems using protocol version 4
(NFSv4), follow this step:
Set the value of the NFS_CLIENT_VERSMAX variable to 4 in the /etc/default/nfs
file, as follows:
NFS_CLIENT_VERSMAX = 4
The NFS_CLIENT_VERSMAX variable specifies the maximum version of the NFS
protocol for communication.
You can also configure the client protocol version to NFSv4 by specifying vers=4 while
mounting the directory. For example, to set the client protocol version to NFSv4 while
mounting the /usr/kc directory, enter the following command:
mount -o vers=4 serv:/usr/kc /usr/kc
For more information on NFSv4, see nfsd(1m), mount_nfs(1m), nfsmapid(1m), and
nfs4cbd(1m).
