USS_CLIENT_MOUNTS

Description:

This check will generate an exception when a file system is found that is function shipping but could be mounted locally.

Reason for check:

File systems should not function ship if they can be mounted locally to avoid performance degradation.

z/OS V1R10 and later.

User override of IBM® values:

The following shows the default keywords for the check, which you can override on either a POLICY statement in the HZSPRMxx parmlib member or on a MODIFY command. This statement may be copied and modified to override the check defaults:

BPXH065E One or more file systems that should be locally mounted are    
available through a remote system.                                      
                                                                        
  Explanation:  Check USS_CLIENTS_MOUNTS found one or more file systems 
    that are should be locally mounted.  This condition occurs in a     
    shared file system configuration.  The file system was intended to  
    be mounted locally but either the local or the owning physical file 
    system has become inactive.  The file system is made available      
    through a remote mount on the owning system.                        
                                                                        
  System Action:  The file system is available through the remote system
    for processing.                                                     
                                                                        
  Operator Response:  N/A                                               
                                                                        
  System Programmer Response:  The file system should be accessible     
    through a local mount.  Determine why it is not and correct the     
    situation.  The original mount of the file system may have failed   
    because the file system is not accessible from the local system.    
    The file system may have been correctly mounted and subsequently    
    converted to a remote mount if the physical file system is no longer
    active.                                                             
    If the physical file system is TYPE(NFS), make sure that TCPIP is   
    operational on this system.                                         
                                                                        
    Otherwise, it may be necessary to unmount the file system and then  
    mount it again.
