Action/
Possible Failing FRU
If the system is not connected to
an active network or if the target
server is inaccessible (this can also
result from incorrect IP parameters
being supplied), the system will still
attempt to boot. Because time-out
durations are necessarily long to
accommodate retries, the system
may appear to be hung.
Restart the system and access the
firmware SMS utilities. In the
utilities check:
v Is the intended boot device
correctly specified in the boot
list?
v Are the IP parameters correct?
v Verify the network connection
(network could be down).
v Have network administrator
verify the server configuration for
this client.
v Attempt to "ping" the target
server using the SMS "Ping"
utility.
Refer to checkpoint E174.
