Description Jure Pečar 2019-07-18 11:58:41 UTC

Description of problem:

I'm exploring the bare metal openshift options, so far with no luck. Deploying openshift requires some nodes to be installed with CoreOS. On one type of hardware I have (IBM HS23 blades) network card is not recognized (Emulex, be2net driver) and installation cannot pull the image. On another type of hardware I have (Dell R410) raid controller is not recognized and no disks are available for installation to proceed.

Version-Release number of selected component (if applicable):
4.1.0

How reproducible:
With this hardware, always.

Steps to Reproduce:
1. Find random old hardware
2. Try deploying CoreOS on it
3.

Actual results:
Installation fails.

Expected results:
Installation should succeed.

Additional info:
There is no HCL provided for CoreOS as is for RHEL so I cannot tell in advance what hardware do I need for baremetal openshift deployment to work.

Comment 1 Colin Walters 2019-07-18 12:42:29 UTC

RHEL CoreOS *is* RHEL.  This type of thing is exactly why the name includes RHEL. There is no separate HCL.

If those devices aren't on the RHEL HCL, they aren't supported.  I know several old hardware RAID controllers were indeed dropped from RHEL 8 (which RHCOS currently tracks).

Comment 2 Jure Pečar 2019-07-18 13:09:29 UTC

Ok, so you're saying that RHEL8 HCL applies to RHCOS 4.1? Valid answer, but I would like to see it mentioned somewhere in the documentation.

With that, I can happily recommend that we trash most of our old hardware, since it's not usable even for the lab ;)

Comment 3 Colin Walters 2019-07-18 13:18:16 UTC

Yes...this does need to be documented.  And I think it's another argument for having the underlying OS version clearly exposed too.

Adding Ben Breard to the discussion.

Hi Steve Milner,

Please find my question at comment 6 ( I kept it private because it has RH internal only URL ).
And Would you please give me any news on this bz ?

I am grateful for your help and clarification.

Thank you,

BR,
Masaki

Comment 9 Micah Abbott 2019-11-08 22:25:53 UTC

Customers should reference the RHEL 8 HCL when evaluating infrastructure to run OCP/RHCOS.
