Mount command syntax and examples
Use the TSO MOUNT command to make a connection between a mount point on your local file system and one or more files on a remote AIX, UNIX, , or other file system. The MOUNT command can only be used by a z/OS superuser.
- Specifies the name of the file system to be added to the file system hierarchy. This operand is required. The file system name specified must be unique among previously mounted file systems. It may be an arbitrary name up to 44 characters in length of a filesystem. You can enclose file_system_name in single quotes, but they are not required.
- Specifies the type of file system that performs the logical mount request. The NFS parameter must be used.
- Specifies the path name of the mount point directory, the place
within the file hierarchy where the file system is to be mounted.
The local_mountpoint specifies the mount point path name. The name
can be a relative path name or an absolute path name. The relative
path name is relative to the current working directory of the TSO/E
session (usually the home directory). Therefore, you should usually
specify an absolute path name. A path name is case-sensitive, so enter
it exactly as it is to appear. Enclose the path name in single quotes.
Note: The mount point must be a directory. Any files in that directory are inaccessible while the file system is mounted. Only one file system can be mounted to a mount point at any time.
- Specifies the type of access for which the file system is to
RDWR specifies that the file system is to be mounted for read and write access. RDWR is the default option.
READ specifies that the file system is to be mounted for read-only access.
- PARM('hostname:"path_name,server_attributes", client_attributes')
- Specifies the hostname of the remote NFS server, the path name
of the UNIX file or MVS data set to be mounted, the server attributes,
and the client attributes.
See Initialization attributes for the z/OS NFS server for descriptions of the server attributes, including the mvsmnt processing attribute to be used with mount commands using the NFS version 4 protocol. The
client_attributesused on the PARM parameter are the same as the NFS client attributes, although some attributes cannot be used on the mount. See Table 1 for a list of the parameters that can be used to specify client attributes on the MOUNT command.
path_name and server attributes are delimited with double quotes. path_name and server attributes are not parsed for validity by the z/OS NFS client. path_name is defined as the characters between the first double quote and the first comma before the server attributes. server attributes is defined as the characters between the first comma after the path_name and the second double quote.
If the path_name has no colon and if no server attributes are specified then the double quotes can be omitted. Enclose the entire string in single quotes. path_name is defined as the characters between the colon after the hostname and the first comma before the client_attributes. Any syntax errors that occur after the colon and before the first comma can cause the mount to fail. If the automount facility is being used, the single quotes should not be specified.

for details about the TAG keyword. Note: When TAG is specified, xlat(Y) must not be specified; otherwise, mount will fail.
