Use the showattr command to display the default attributes
or the attributes that have been set for a specific mount point.
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.
If you omit the hostname, you must specify the /localpath.
Table 1 shows examples of the showattr
command for some clients.
Table 1. Examples of the
showattr command for clients| Client Environments |
Command Examples |
|---|
| AIX, UNIX |
showattr mvshost1 /u/smith/mnt |
| z/OS |
showattr mvshost1 /u/smith/mnt |
| Solaris |
showattr mvshost1 /u/smith/mnt |
| Linux |
showattr mvshost1 /u/smith/mnt |
Make sure
that your version of the showattr command matches the release of the
z/OS NFS that you are using. Otherwise, the z/OS NFS server attributes
do not display.
These
examples show different ways you can use the showattr and mount commands.
Figure 1 shows
a showattr command with just the host name ( mvshost1 in
this example) specified. The attributes for
the server are displayed. Figure 1. Displaying server attributes# showattr mvshost1

Figure 2 illustrates the showattr command
being used to display the attributes for the z/OS host named mvshost1 as
well as the mount point, /u/smith/mnt.
Figure 3 also illustrates
the specified options: a second showattr command, where the client
user specifies /u/smith/mnt in addition to mvshost1.
This shows the user's specified settings at
that mount point, rather than the settings in the attributes data
set. Figure 2. Displaying
mount point attributes. The client user changed the space(100,10),
blks, and binary attributes to space(5,0), trks, and text for the
mount point /u/smith/mnt, and then specified that
mount point in the second showattr command.# mount mvshost1:"smith,text,space(5,0),trks" /u/smith/mnt
# showattr mvshost1
