/etc/auto.master

The /etc/auto.master file contains the directory or directories that the automount facility will monitor. It also contains an associated MapName file that contains the mount parameters.

Figure 1 is an example of a /etc/auto.master file. It specifies that the automount facility is to manage the /u directory. If someone using kernel services tries to access a directory in the /u directory, the automount facility automatically mounts the data set based on the MapName policy in Figure 1.

Figure 1. Example of an /etc/auto.master file. It is named /etc/u.map.

/u                /etc/u.map

The name of the map file can be specified as a data set name. The data set name must be specified as a fully qualified name and can be uppercase or lowercase. Single quotation marks are not needed. For example:

/u //sys1.parmlib(amtmapu)
