rp7410 IODC ENTRY_INIT failed, boot problems

[klb]

Hello,

I have an rp7410 ( only one cell ) that recently went down with power issues on the IO Chassis.  This was traced to a bad VRM and a bad PCI Brick.  I now have no Faults in the ps listing from the MP and the Cell joins the partition without issue. 

The BCH errors on BO PRI with IODC ENTRY_INIT failed.  I've seen status= -8 and -4.  The internal disks have green lights and appear to be functioning properly.  

What could be causing this?  I know there was a good, running OS ( 11.11 ) on the main boot disk prior to our power issues and this ~may~ have been mirrored to the secondary boot disk.  When I do a BO ALT or a BO HAA, I get "bad LIF MAGIC" error.

Another oddity is that sometimes a SEA will return 3 paths and sometimes only 2.  Here are all three with notes:

P0 1/0/0/3/0.6 
P1 1/0/0/3/1.2          -- This one is the one that sometimes does NOT show up on an SEA
P2 1/0/1/0/0/1/1.6

Can you guys point me to a document that might help me troublshoot this further and/or determine the cause?  I'm particularly interested in decoding those status values.

I've attached a file, session.txt, containing MP listings of stuff and an attempted boot with associated errors.

Any help here is appreciated, thanks,

Note also that a BO 1/0/0/3/1.2 gives the same IODC error with status=-8

Accordintg to that document, our error ( status = -8 ) is telling us that the boot disk has not completed its power up and/or selftest.  

The disks are showing good green lights on the front of the 7410 and appear to be functioning properly.  We're going to do the test procedure in the document ( boot and watch for access lights on the disk(s) ).

Any other tips or ideas as to why we might get status = -8 and what else we can do to troubleshoot further?

Thanks again,

Hi,

Thank you very much for the update. My Suggestions would be:

1) Please follow the "Troubleshooting Steps" provided in that document.

2) If the issues is still persist, Please log a Hardware call with " HP Solution Center"

Continue to get IODC ENTRY_INIT failed with -8 when attempting to boot from the PRI device, but get bad LIF magic when trying to boot from ALT and/or the DVD.  We do have a bootable media in the DVD drive.

SEA finds both internal disks and the DVD, but any attempt to boot from those devices fails with the errors mentioned.

Anybody on the board have further suggestions?  We're going to pay T&M to HP to fix this and I want to make sure they don't just start throwing expensive parts at it.  What are the next diagnosis steps that I can perform here to get to the cause of the problem.  BTW, don't think it is failed drives because all internal drives didn't fail at the same time I'm pretty sure!  

We reseated the Mass Storage Backplane, the Cell board, all PCI cards, including the LAN/SCSI card.  No Joy.  Prior to getting to this point, we had trouble with one of the VRMs on the PCI backplane and the PCI power brick, both of which were replaced.  After getting past these power issues, we now cannot get past BCH due to the above problems.

The disks blink green a bit after being plugged in but that's it.  No access at boot time.

Thanks,

Bad LIF Magic means the system cannot read the disk as bootable.  Is the DVD HP-UX Install media that you know boots otherwise?

In regards to the primary boot disk, it is behaving as a bad disk might.  Without the ability to boot into another environment this is tough to confirm.  Something to try...

Move the primary disk to the alternate disk location, reset the partition and try again.  if the same symptoms follow the disks you are likely dealing with a disk issue.   As far as the DVD goes (assuming you know the media is good), could this be a seperate issue?  Can you attach another DVD drive to test?

Lastly, is to utilize an Ignite server on the network and boot from the network.  if you can get into an HP-UX installation utility you can scan the HW to see what disks are seen at that level.
