The returned status is not always sufficient to distinguish between a network that is<br />

down and a host that is down. See the "No route to host" message.<br />

Action<br />

Check the network routers and switches to see if they are disallowing these packet<br />

transfers. If they are allowing all packet transfers, check network cabling and<br />

connections.<br />

Technical Notes<br />

The symbolic name for this error is ENETUNREACH, errno=128.<br />

NFS getattr failed for server <strong>string</strong>:<br />

RPC: Timed out<br />

Cause<br />

This message appears on an NFS client that requested a service from an NFS server<br />

whose hardware is failing. Often the message "NFS read failed" appears along with<br />

this message. If the server were merely down or slow to respond, the "NFS server<br />

not responding" message would appear instead. Data corruption on the server<br />

system is possible.<br />

Action<br />

Because this message usually indicates server hardware failure, initiate repair<br />

procedures as soon as possible. Check the memory modules, disk controllers, and<br />

CPU board.<br />

performance in the System Administration Guide, Volume II.<br />
