ITEM: DD1556L
Network boot leds 511 622 then blank
Question:
Env:
AIX 4.2
RISC E30 (server CW) SP High Node
sysback 4.1.1.5
Problem:
When the customer tries to do a network boot from the E30
onto the High Node it hangs on these leds 511 622 then blank
Action Taken:
It appears to be failing on the cfgcons command
I will make sure the customer has installed all the
needed filesets on the E30 to support his serial adapter
on the High node.
devices.mca.dee6
Standard I/O (dee6) Adapter Software
devices.mca.df5f
Standard I/O (df5f) Adapter Software
devices.mca.fed9
Standard I/O (fed9) Adapter Software
devices.mca.f6fe
Standard I/O (f6fe) Adapter Software
devices.sio.sa.rte
bos.rte.tty
These were all installed on the E30, reboot and the boot image
recreated, which still did not fix the problem.
I made sure the customer did not have a symbolic link
of /etc/objrepos/Config_Rules to /usr/lib/Config_Rules
I had the customer put the network boot into debug mode:
How to debug a network boot...
-------------------------------
REQUIREMENTS
Sysback 3.3.2+
Any Ascii Terminal
STEPS TO BE DONE ON THE SERVER SYSTEM
-------------------------------------
1. cd /usr/sbin
2. cp mksbnetboot mksbnetboot.org
3. vi mksbnetboot
Search on bosboot (It should be found on your second hit)
Change:
bosboot -a -d $DEVICE -p $tmp_proto -b $BOOTIMAGE \\
-k $bootdir/unix_$kernel -T $platform
To:
bosboot -Ia -d $DEVICE -p $tmp_proto -b $BOOTIMAGE \\
-k $bootdir/unix_$kernel -T $platform
(Add a -I (upper case i) flag to the command)
Save the file
4. Create your boot image:
/usr/sbin/mksbnetboot -B -d'ethernet' -T'rs6k' -k mp
(if your client is using a ethernet network)
5. nm -x /usr/lib/boot/unix_mp | grep enter_dbg
Example output:
enter_dbg D 0x001801f4 0x0004
Write down the second fields number
From the example above write this number down.
1801f4
STEPS TO BE DONE ON THE CLIENT SYSTEM
-------------------------------------
6. Start the network boot on the High Node
7. After the bootp and tftp are done the ascii terminal will display
the kernal debugger information.
Type this from the command prompt:
> st 1801f4 2
> g
The console (cfgcon command) is not getting configured. It is
failing with this error message:
cfgcon: console is not defined and no candidate terminals were
detected
Looking through the debug output it seems to fail on these entries
a great deal

It appears that the customer is able to do a NIM boot from
this source /source/aix/420
I had the customer send me this information:
--------------------------------------------
lslpp -L > CW.lpp.list (list of fileset installed on the E30)
ls /source/aix/420 > lpp.source (list of filesets in the lpp
source used by NIM booting)
I noticeds these filesets on the control workstation at different levels than
in the user SPOT.
What is on the control workstation (E30):
-----------------------------------------
devices.mca.8f97.com 4.2.1.0 Common SSA Adapter (8f97)
devices.ssa.IBM_raid.rte 4.2.1.0 SSA Raid Manager Software
devices.ssa.disk.rte 4.2.1.0 SSA DASD Software
The matching filesets are at 4.2.0.0 level in the NIM SPOT
This could be our problem. The customer has 8 SSA adapters
installed on the system.
I had the customer remove those filesets above, reboot and
rebuild the network boot image which fixed the problem.
Action Plan:
Closing with customer approval
