Boot

Problems

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Depending

on

the

boot

device,

a

checkpoint

may

be

displayed

on

the

operator

panel

for

an

extended

period

of time

while

the boot image is retrieved

from

the

device.

This is particularly true for Tape and Network boot attempts.

If

the checkpoint/code i

displayed

for an extended time there

may be a problem loading

the

boot

image

from

the device. If booting from CDROM

or

Tape,

watch

for

“activity”

on

the

drive's

LED

indicator. A blinking LED means that

the

loading

of either

the

boot image

or

 

 

additional

information

required

by

the

operating

system

being

booted

is

still

in

 

progress.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For

network

 

boot

attempts,

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 still attempts to boot and because time-out durations are

necessarily

long

to accommodate retries,

the system

may appear to be hung.

1. Restart

the

system and get to the

Firmware SMS

utilities. In the utilities check:
