This operand is used to specify a replacement for one of the NFS control data sets. This applies to either the lock data sets or the mount handle data base data sets. When the z/OS NFS server determines that one of the control data sets has become unusable, it will write a warning message to the operator console requesting that the broken data set be replaced. Rename or delete the broken data set, allocate a new data set with the original name, and issue the MODIFY Addds command to enable the new data set. If the ddname does not match one of the valid control data set ddnames that has been freed, an error message is written. If the system programmer chooses not to replace the broken data set, the server will continue processing with the remaining data set. If a different data set name is used, the corresponding data set name in the NFS server startup procedure must be changed. Enter the operand as follows:

>>-+-MODIFY-+--mvsnfs,addds=ddname(dsname)---------------------><
   '-F------'                                

where

ddname

is the ddname of the NFS server control data set that is to be replaced. The valid ddnames are: FHDBASE, FHDBASE2, LDBASE, LDBASE2.

dsname

is the name of the lock data set or mount handle data set to be enabled for use by the z/OS NFS server.
