Displaying default and mount point attributes

Use the showattr command to display the default attributes or the attributes that have been set for a specific mount point of the z/OS NFS server. If you specify a mount point, showattr shows the attributes for the mount point, including the overriding values. For descriptions of the attributes, see Initialization attributes for the z/OS NFS server and Mount command syntax and examples.

If you omit the hostname, you must specify the /localpath.

The following is an example of the showattr command.

showattr mvshost1 /u/smith/mnt

Make sure that your version of the showattr command matches the release of NFS that you are using. Otherwise, the NFS server attributes will not display.

These examples show different ways you can use the showattr command.

Figure 1 shows a showattr command with just the hostname (mvshost1 in this example) specified. The attributes for the server are displayed.
