Overriding data set creation attributes

When you create an MVS file, default file creation attributes are applied, unless you override them. The attributes are passed to the z/OS host.

Data set creation attributes are controlled in the following ways, in increasing order of priority.

Default server data set creation attributes
Default installation data set creation attributes, specified by the system administrator in the attributes data set
DFSMS data class attributes
Data set creation attributes specified in the mount (or nfs link) command
Data set creation attributes specified in the mkdir, vi (edit), or cp (copy) commands (highest priority)

The z/OS NFS server does not support the following data class attributes.
