Openscape 4000 V8 R2 Booting Issue – System Always Boots as CCB

[Ashraf Aziz]

Dear team members.

I am currently working with a system running Openscape 4000 V8 R2 (please see the attached image for reference).

I am facing the following issue:

1. Both HD1 and HD2 have crashed and are no longer booting.
2. I had a single hard disk in the CCB processor, and the system could successfully boot from this hard disk using either the CCA or CCB processor without any problems.
3. I cloned the original disk using HDClone software, and now I have three identical hard disks that are all functioning correctly.

Current Issue:
Despite having identical working hard disks, the system always boots as CCB.
I would like to know the steps required to ensure the system boots as CCA.

Your assistance on this matter would be highly appreciated.

Best regards,
Ashraf Aziz

I would boot CCB and then start Node Replacement on CCB from the Platform Portal. It should be more or less self-explaining.

* Start Node Replacement
* Boot the broken CCA Node…

Yes I have try node replacement but system waited one hour after CCA wad not able to communicate with target node CCB
I connect cables Eth4 To Eth4 and Eth6 To eth6

Note My both processes are Booted as CCB


Please advise

Node Replacement should work also with a completely empty SSD, Node Replacement should flush it completely.

Not sure about the ethernet cables for now, but afair the corosync LAN would be the important one. I assume it is defined in the firstinstall…xml. Maybe doublecheck the settings there as well.

What does Node Replacement log say?

Sorry, have no clue on this anymore.

Next i would check the network… tcpdump on the interface or connect Lan cables to a network switch and trace there. See if you see any communication at all via corosync?? Dunno, just a thought.

It could be the BIOS of the DSCXL is set to boot from HD before network.

Node Replacement is the correct way to recover this. Or reinstall as CCA from a USB stick.

It needs a keyboard and screen on the processor, reboot, into BIOS, check config, watch what happens when it reboots with node replacement running on the other node.

"Despite having identical working hard disks, the system always boots as CCB.". Of course it boots as CCB. All three hard discs are CCB discs. If you want a CCA processor you have to create a CCA disc.

Messing around with this when you don't know what you're doing is a good way to corrupt the DB and then you'll have neither CCA nor CCB.

Thanks for your advice,
I do have networking switches but
I have no idea how to check corosync communication,
