RP7410 crashes when slave core I/O added

I have 2 Rp7410's that are doing the exact same thing so I don't think it is a bad core I/O. I built the systems with 2 cells fully populated and a single core I/O with no errors. when I added the second (slave) core I/O it crashed during boot. There were no erros until I tried to boot. Also, there were no fault lights afterwards. I am completely stumped. I have swaped out every part possible with the same results. The strange part is that the systems are fine until I try to boot.
thanks,
Craig

Re: RP7410 crashes when slave core I/O added

We are talking about core I/O sets. Each set consists of an MP card and LAN card. So you have to add 2 components as a second core I/O.

Can you confirm this?

Hope this helps!

Re: RP7410 crashes when slave core I/O added

In other words:

one core I/O set consists of a MP card (not a PCI card) and a LAN card (PCI card).

two core I/O sets are 2 MP cards and 2 PCI cards per server.

Hope this helps!

Torsten.

Re: RP7410 crashes when slave core I/O added

yes, I installed the second MP into the top slot and the LAN/SCSI card into 0/1 (bay 0, slot 1). I don't need to attach or change any of the ribbon cables, do I? I also swapped MP's (master and slave positions) with the same results. Works with one installed but not 2

Re: RP7410 crashes when slave core I/O added

There are 2 different types of sets. They must not be mixed in one system.
What type do you have?

Another point is firmware.
get and post

GSP:CM> sysrev

Hope this helps!

Torsten.

Re: RP7410 crashes when slave core I/O added

Hi Craig,

Can you check the MPs SL logs to see if some info being logged there?

Do you see the Master LED of both MPs lit up ( which is not correct )?

Re: RP7410 crashes when slave core I/O added

Hi Craig,

You have tried to swap the MP, but have you tried to swap the LAN Core I/O? The panic is showing I/O system hangs.

My guest, it is either the Lan Core I/O or the I/O Backplane could be defected

Regards,
Sandy

Re: RP7410 crashes when slave core I/O added

Is this server sharing disks with another? Make sure the SCSI addresses on the bus, whether shared or dedicated, are unique. Also check for improper SCSI termination or none at all.

Re: RP7410 crashes when slave core I/O added

What happens with 2 MP and 1 LAN card?

The second LAN is an option, so it works with only 1 LAN card (part of the core I/O set).

Does it work?

Hope this helps!
Regards
Torsten.

Re: RP7410 crashes when slave core I/O added

the disks are not being shared. Can you set the scsi ids on the internal drives? I swapped out the MP's and the Lan/scsis. Logs show nothing out of the ordinary. Do I have to change any of the interanl cabling? I just can't believe that this is a hardware issue because I have duplicated the error in both systems. I think it has something to do with the drives but I can't pin it down. I have 10+ years experience in HP hardware and I am banging my head against the wall on this one!

Re: RP7410 crashes when slave core I/O added

Oh, and I have tried to bring it up with one LAN/SCSI and to MPs with the same results..

Re: RP7410 crashes when slave core I/O added

I summarize:

You switched the power off and installed a second MP to the upper slot. One LAN card is inserted in the most right, one in the most left slot. The system is failing.
You did try with 2 MPs and 1 LAN card in the most right slot. Same result. Right so far?

Hope this helps!
Regards
Torsten.

Re: RP7410 crashes when slave core I/O added

that is correct. I also did soft resets to the MPs and full shutdowns. Also, pulled the batteries on the MPs to blow away any image that was saved on them and I even started completely over by running the cc command and brought the system back to one cell, two procs, one set of mem and one drive. And always came back to the same point. Everything works great until the second mp is installed.

Re: RP7410 crashes when slave core I/O added

Please try this:

Shutdown the OS, *don't* power off the system.
Install the second MP now.
Reset the system and try to boot.

Re: RP7410 crashes when slave core I/O added

If you have installed additional drives in the 2 lower slots pull them as they be causing bus faults.

Would you please update your thread?
Could be interesting.

Hope this helps!

Re: RP7410 crashes when slave core I/O added

Sorry, was out of the office... I pulled the bottom drives and tried to come up with the lan/scsi in and out. Still crashing. I have been running the systems without the slave core in. they work just fine without them. Can someone tell me the latest firmware rev? Maybe that's the problem...
Torsten.
Acclaimed Contributor

Re: RP7410 crashes when slave core I/O added

Latest firmware is revision 6.5

Go to the MP:CM> and do sysrev

Should look like this:

MP:CM> sysrev
Cabinet FPGA and Firmware revision report
System Backplane : GPM FM OSP
------- ------- -------
1.002 1.002 1.002
PCI Backplane : LPM HS

FPGA MP

Master Core IO : 2.008 4.025

Did you try to insert the MP while the OS is down but power switch is on?

Hope this helps!

Torsten.
