Table 7 describes the NFS client daemons and their functions.

Table 7 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.

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” (page 36)

(Required)

• “Enabling an NFS client ” (page 36) (Required)

• “Mounting remote directories ” (page 36) (Required)

• “Changing the default mount options” (page 40) (Optional)

• “Unmounting (Removing) a mounted directory” (page 40) (Optional)

• “Disabling NFS client capability” (page 41) (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 21).

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

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
