NFS Services Administrator's Guide (B1031-90072, March 2011)

procedure calls that enable the client to transparently access the filesystem on the server’s disk. To
users, these mounted remote directories appear as if they are a part of the local filesystem. An
NFS client can also be an NFS server. NFS filesystems can also be automounted using AutoFS.
For information on how to automount a filesystem, see Chapter 3: “Configuring and Administering
AutoFS” (page 47).
NFS Client Configuration Files and Daemons
This section describes the NFS client configuration files and daemons.
Configuration Files
Table 6 describes the NFS configuration files and their functions.
Table 6 NFS client configuration files
FunctionFile Name
Contains the list of filesystems that are currently mounted./etc/mnttab
Contains the default distributed filesystem type./etc/dfs/fstypes
Contains the list of filesystems that are automatically mounted at system boot time./etc/fstab
Daemons
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.
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” (page 34)
(Required)
• “Enabling an NFS Client ” (page 34) (Required)
• “Mounting Remote Directories ” (page 35) (Required)
• “Changing the Default Mount Options” (page 38) (Optional)
• “Unmounting (Removing) a Mounted Directory” (page 38) (Optional)
• “Disabling NFS Client Capability” (page 39) (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 20).
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.
