</PRE>
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>fs getclientaddrs</B> 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.
|
|
<P>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
|
|
accessible.
|
|
<P>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.
|
|
<P>The <B>fs setclientaddrs</B> reference page 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.
|
|
<P><STRONG>Cautions</STRONG>
|
|
<P>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
|
|
reply.
|
|
<P>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
|
|
<B>fs setclientaddrs</B> command to change the list and then rebooting
|
|
each relevant File Server immediately.
|
|
<P>The displayed list is not necessarily governing the behavior of a given
|
|
File Server, if an administrator has issued the <B>fs setclientaddrs</B>
|
|
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.
|
|
<P>The list of interfaces does not influence the Cache Manager's choice
|
|
of interface when establishing a connection to a File Server.

|

</DL>
|
|
<P><STRONG>Output</STRONG>
|
|
<P>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.
|
|
<P><STRONG>Examples</STRONG>
|
|
<P>The following example displays the two interfaces that the Cache Manager is
|
|
registering with File Servers.
