I've got code: 888 102 700 C20 when starting a NIM install. (Tried the online search results and it hasn't worked)
The OS is AIX 7100-03-02. The lpp_source and spot were defined as such:
The 888 102 700 C20 appears when loading the kernel (the bootp and tftp transfer appears to complete fine):
How can I run stuff in debug mode or access the kernel messages during initial network NIM boot to get more information on the error? How can I get more information as to what's wrong or what is happening here?
The 7100-03-02 lpp was defined based on AIX 7100-03-00 DVD image then the copied lpp_res was updated using the fixpack bff's (to 7100-03-02). That process completed without an issue and checks on the spot/lpp were fine.
Cheers,
DH

I would first consider if the hardware & firmware version supports AIX 7. You can get the hardware boot codes from a search on the IBM site using this tool:-
Search for "three digit display AIX". The meaning of these codes is more or less fixed over all sorts of hardware. "888" means "system dump", "102" is a system halt. "700 c20" is the reason for this happening, in this case a program interrupt (700) where the kernel debugger exited without finishing the dump (c20).
Here is one site of many describing three-digit-codes in general and this one in specific.
Yes I saw that link and went over it as well as others so have an idea what the code means. When starting the NIM network install with debug mode, I get this:
AIX Version 7.1
Starting NODE#000 physical CPU#001 as logical CPU#001... done.
Illegal Trap Instruction Interrupt in Kernel
.kexitx+000430 tweqi r0,0 r0=0
Earlier I already had installed AIX 7.1 on the hardware and it was working and still is working fine. But new installs fail now. I did do the installs through NIM earlier as well but with a lower 7.1 TL and SP level. Tried to use a TL02 SP3 level with 7.1 and it produced the same code. So thinking the way the NIM was redone could be the issue but feel I'm missing bits and pieces of information off the NIM that could move this further for me. Like I said, I upgraded the 7100-03-00 DVD image to 03-02 from the fixpacks so not sure if things got mixed up in that somehow. How can I check for that? Or perhaps there's something messed up with the HMC profile that I can check for vm02 as it's virtualized through a VIO?

Its is just gut feeling, but maybe you need to update some microcodes to support new OS versions?
Do installs of the old TLs/SPs still work or do they produce the problem too?
I want to install single RPM from LPP on NIM system without doing it interactively (with single non-interactive command), so I 'got' that command from smitty this way:

Hello,
Is it possible to install up-to-date vios in one NIM operation ?
For example I have vios v2.1 DVD and current vios version is v2.2.1.3(we update to fixpack v2.2.1.1_FP25 and apply service pack 2.2.1.3-FP25-SP01)
I know it's possible if we install AIX using NIM - we just update... (0 Replies)
Hi all,
I have created VIO Server which serves 3 lpars. All of them are on VLAN ID 50.
From one lpar I installed and set up NIM master server called testAIX1.
I have created client and allocated resources to it:
testAIX1:/ > lsnim -l test_lpar
test_lpar:

Has anyone ever done this and is it easy to do with SLES9/10? All I can find so far is this link

Can you still use all the feature of autoyast etc?
