Follow the repair action listed
for checkpoint E151.
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.
