       fs_getclientaddrs - Displays the client interfaces to register


       fs getclientaddrs [-help]

       fs gc [-h]

       fs getcl [-h]


       The fs getclientaddrs command displays the IP addresses of the
       interfaces that the local Cache Manager registers with a File Server
       when first establishing a connection to it.

       The File Server uses the addresses when it initiates a remote procedure
       call (RPC) to the Cache Manager (as opposed to responding to an RPC
       sent by the Cache Manager). There are two common circumstances in which
       the File Server initiates RPCs: when it breaks callbacks and when it
       pings the client machine to verify that the Cache Manager is still

       If an RPC to that interface fails, the File Server simultaneously sends
       RPCs to all of the other interfaces in the list, to learn which of them
       are still available. Whichever interface replies first is the one to
       which the File Server then sends pings and RPCs to break callbacks.

       fs_setclientaddrs(1) explains how the Cache Manager constructs the list
       automatically in kernel memory as it initializes, and how to use that
       command to alter the kernel list after initialization.


       The File Server uses the list of interfaces displayed by this command
       only when selecting an alternative interface after a failed attempt to
       break a callback or ping the Cache Manager. When responding to the
       Cache Manager’s request for file system data, the File Server replies
       to the interface which the Cache Manager used when sending the request.
       If the File Server’s reply to a data request fails, the file server
       machine’s network routing configuration determines which alternate
       network routes to the client machine are available for resending the

       The displayed list applies to all File Servers to which the Cache
       Manager connects in the future. It is not practical to register
       different sets of addresses with different File Servers, because it
       requires using the fs setclientaddrs command to change the list and
       then rebooting each relevant File Server immediately.

       The displayed list is not necessarily governing the behavior of a given
       File Server, if an administrator has issued the fs setclientaddrs
       command since the Cache Manager first contacted that File Server. It
       determines only which addresses the Cache Manager registers when
       connecting to File Servers in the future.

       The list of interfaces does not influence the Cache Manager’s choice of
       interface when establishing a connection to a File Server.


           Prints the online help for this command. All other valid options
           are ignored.


       The output displays the IP address of each interface that the Cache
       Manager is currently registering with File Server processes that it
       contacts, with one address per line. The File Server initially uses the
       first address for breaking callbacks and pinging the Cache Manager, but
       the ordering of the other interfaces is not meaningful.


       The following example displays the two interfaces that the Cache
       Manager is registering with File Servers.
