GFSA572E

Explanation
 After initialization, the z/OS NFS server did
not receive the domain name of the host name from DNS  which is needed
to perform NFSv4 mounts. In the absence of a domain name, subsequent
NFSv4 mounts will be rejected with GFSA571E message. In the message
text: 
 hostname
The host name for which the z/OS NFS server was unable to get
a domain name. 
funcname()
The name of the function that did not return the domain name.

System action
 z/OS NFS server processing continues.

System programmer response
 This message has two system programmer
responses.
 If it is preceded by GFSA556I console message, then the z/OS NFS
server cannot get a domain name because of inoperable  DNS. If customer
intends to use NFSv4 protocol operations, ensure the DNS resolver
is active. If not active, restart DNS and then the z/OS NFS server.

In the absence of GFSA556I console message, correct the DNS data
content. This content should reflect the correct domain  names. Restart
the z/OS NFS server.
