Hi all,
I'm freshman in this forum. I'm here to ask for your help. A case about Sun Fire V490. But, before starting to ask, I want to tell you the story.
Last week, I was told about a failed V490 in Da Nang City (Vietnam). It could NOT boot. After diagnosing it remotely, I found that the problem may be on the Centerplane Board. So, I took a Centerplane from a running V490 in Ho Chi Minh City and flied to Da Nang City. After replacing the centerplane, the V490 in Da Nang showed the errors :
1:0>ERROR: TEST = Run POST from Memory
1:0>H/W under test = CPU1, All CPU1 Memory
1:0>Repair Instructions: Replace items in order listed by 'H/W under test' above.
1:0>MSG = Incorrect checksum detected!!
Expected: ae51
Observed: 119
1:0>END_ERROR
It was NOT the errors before centerplane replacing.
OK. I called to Ha Noi City and they sent me another V490 the following day. I took the Centerplane from it and put it in the V490 in Da Nang. Problem was solved !
So, obviously, the centerplane caused the errors. But, it was abnormal when I take my Centerplane back to Ho Chi Minh City, put it in the V490 in my site, it showed exactly the errors I saw in Da Nang :
1:0>ERROR: TEST = Run POST from Memory
1:0>H/W under test = CPU1, All CPU1 Memory
1:0>Repair Instructions: Replace items in order listed by 'H/W under test' above.
1:0>MSG = Incorrect checksum detected!!

I don't know why and how this errors could occur ! Please advice !
The V490 in Da Nang was NOT able to see the two internal FC disks. So I thought that the problem may be on the disk backplane or the data cable from the disk backplane to the centerplane or the diskbackplane power cable or the centerplane. I replaced everything of those but the centerplane, the errors were NOT changed. But when I replaced the centerplane (with the one from HCM City - my site), the errors were what you see in the previous post. And with the centerplane from HN City, everything's OK.
Those errors came from the POST level. I can't reach the ok prompt nor the OS.
Yes, there are differences. The V490 from Da Nang and Hanoi are exactly the same, with two CPU/memory boards; two 1,35 GHZ CPUs and 4 GB of RAM per board. The V490 from HCM has one CPU/memory board with two 1,5 GHZ CPU and 8 GB of RAM. The OPB version of the HCM's V490 is lower than HN's and DN's.
I don't think the NVRAM caused the errors. It's located on the I/O board, not the centerplane. Just remember, the V490 was running smoothly before i took the centerplane out for testing in Da Nang.

i'm trying to remember but i feel as if the obp may need to be upgraded because of the cpu difference. are the obp levels the same on both boxes (if you can remember).
i was saying to swap the new nvram with the old nvram so that you keep your old settings.
No, i think you might have misunderstood the situation. The V490 in HCMC ran fine. But I took it centerplane away, and when i put it back, it does NOT run anymore. There's no change in the system.
Is it possible that the centerplane was wrecked in transporting ? Or when i plugged it in the V490 with different CPU/Memory board, it was dumped ?
I'd thought of upgrading OBP. But how can I do it, while I can't pass the POST level ?
