Information About This Version Known Problems and Workarounds GDS Required for X.500 Cell Name If a cell is configured with an X.500 style cell name (e.g., c=us/o=hp/ ou=cssl) Enhanced DFS will work only if GDS is also configured in the cell and all GDS (and DCE) daemons are running. UDP/IP Required Enhanced DFS 3.0 requires the User Datagram Protocol of the Internet Protocol suite (UDP/IP). Enhanced DFS will not function across an IP router which filters out UDP traffic. Nearly all IP routers are configured to permit UDP traffic, so this restriction will not pose a problem for most sites. Using the HP-UX mkdir -p Command Care must be taken when choosing pathname arguments to the HP-UX mkdir -p command, which tries to create each directory in the path you specify. Thus: mkdir -p /.../xyz.abc.com/fs/users/kk/dir fails because nothing can be created in the CDS part of the name space ( /... and /.../xyz.abc.com). In most installations, however, /: is a link to /.../ xyz.abc.com/fs; the command: mkdir -p /:/users/kk/dir works (assuming the correct UNIX permissions) because the first directory mkdir -p tries to create is users. Visibility of Global Cell Name Space The Enhanced DFS name space is visible to HP-UX file system commands such as cd and ls. However, the global cell name space only becomes visible as names are used on the system. For example, $ ls /... does not show any subdirectories the first time it is used. However, $ ls /.../mycell (where mycell is a cell name) followed by, $ ls /... 23
