Hi,

We could try to help you here, but we would need a lot more of information... Without going into details, maybe some more obvious steps to avoid the problem(s) and help you getting ready:

• Is there another computer you can try on?
• What Network connection you are using, home? Work? Maybe a firewall is interfering?
• Is there any security enabled like Secure Boot?
• what is the "sha256 " checksum of the iso you used (to verify its integrity): sha256sum rhrexboot.iso

Note: I just used  an iso downloaded a few days ago, and my checksum is:

eda73a25d7d9b5eb51273c1773ee08297d17fb4430200125f3432d2f31ab594f

(I assume that the version I just downloaded is not corrupted and was not updated since then). If our checksum matches, it is unlikely to be about a corrupted iso.

The dm raid errors seems to indicate something is not going on with your raid drivers/controllers. If true, we would have collect more technical information and send it to the relevant team.

Cheers,

my answers:
Network connection used is at home via modem/router supplied by my internet provider. Not using WiFi. it's a simple router without firewall that supplies dhcp IP to any device that requests it. Again no firewall enabled or running - no ports blocked. There is no security enabled - no Secure Boot.
I ran a sha256 checksum against the downloaded iso file using windows certUtil and confirmed it matches your checksum exactly -
eda73a25d7d9b5eb51273c1773ee08297d17fb4430200125f3432d2f31ab594f. I even downloaded the iso several times, confirmed the hash and have the same result.
I am using simple SATA hard drives on my computer - no physical RAID controller - no RAID configured in bios. which brings up another question - why would the process be trying to TOUCH my hard drives? It's booting off of a 16 gig usb device - it shouldn't be configuring RAID for nothing but the usb device.

Hi @douradoden,

• The checksum should be indicating that your iso is not corrupted. 

• About the question about touching your hard drive(s)- Who said the Remote Exam environment is actually touching your hard drive(s)? I said the error message seems to indicate something- as a hint on initiating a technical investigation. I spoke about some hardware components based on the error message. Having said that, when a Live USB environment boot from a computer, it does access some part of the hardware, like CPU, memory, Keyboard, etc... Since it boots from a specific partition on the live usb, it does not access the hard drive data (which is a rather different thing than a hardware raid controller anyway).

Anyway, you could try on any other computer, to have more information about your live usb (if you have that option). You could also provide detailled technical information so we can check with the team creating the Live Exam Environment). We would need screen capture of the problem, all technical info on the computer (brand, version, components, etc...), same for your 16GB USB key. Description on how you are booting... Anything that can help.

Cheers,

"About the question about touching your hard drive(s)- Who said the
Remote Exam environment is actually touching your hard drive(s)?"

YOU SAID IT said it thats who. You said:"The dm raid errors seems to
indicate something is not going on with your raid drivers/controllers"
in a previous response.
Heres the link:
https://learn.redhat.com/t5/General/Questions-about-getting-ready-for-your-Red-Hat-remote-exam/m-p/1...
So you see YOU SAID IT!
I posted a simple question about RedHat's remote exam usb boot process
not working requesting a solution and now you want to argue with me?
The question is what is the dm raid set job trying to do - why is it
throwing a seg fault?
If you have no clue then bump it up to another engineer.

Hi!

There are some news about that after 1 October there will be new objectives in EX200 like containers and openshift. Is this true ?

[vishals]

Hi @AJ17 ,

Yes, Both training (RH124 and RH134) and the exam (EX200) is being updated to include container and OpenShift content. You can read more about it here.

Best Regards,

[AJ17]

Thank you for your answer!

It means, the last day for the Old Ex200 exam (without containers and openshift) will be 30th September?

[vishals]

Hi @AJ17 ,

That is correct. The RHCSA EX200v8 exam has to be scheduled by September 30th to take the exam without container content.
(Note that these changes do not affect the RHEL7 EX200 exam)

Best Regards,

Hi @vishals there are not a transitional period?  I think if the course with the new kubernetes content is launches by 1 October and I schedule an examn of ex200 these day 1 October is very dificult to have the new knowledge by this day. Whats the date when te new content was available on the rol?
